Published August 2026. Every price, warranty term and micron figure below was read off the brands’ own live pages on 29 August 2026.
Of the six demi-fine jewelry brands scored here, Monica Vinader wins on 87.5 points out of 100. Monica Vinader is the only one that prints a gold thickness on the product page you are actually looking at, at least 2.5 microns, and pairs it with a stated 5-year warranty and a published offer to re-plate vermeil that loses its color. Nobody else here does all three.
Three of the six publish no warranty term at all. Mejuri, gorjana and Missoma name no duration anywhere a buyer would look. A fourth, Astrid & Miyu, publishes one year and then excludes plating wear after three months. Every brand on this page sells a product whose gold layer is a consumable. Four of the six will not commit in writing to that layer surviving a season.
That is the whole argument. Here is where each brand lands before the detail:
I’ve worn plated jewelry through enough humid summers to know the color goes at the clasp first. Salt air speeds that up more than any spec sheet admits. That’s why I read a warranty’s exclusions before I read its length.
Quick Picks: Six Demi-Fine Jewelry Brands Ranked
- Best overall: Monica Vinader. Publishes the micron figure at the point of sale, publishes five years, and is the only brand of the six that offers to re-plate.
- Best disclosure per dollar: Mejuri. The same 2.5 microns for $118 instead of $220, which works out to $47.20 per published micron against Monica Vinader’s $88.00.
- Best warranty wording: Ana Luisa. Two years, and the policy names tarnishing out loud instead of hiding it under general wear.
- Cheapest of the six pairs priced here: gorjana, at $70. You save money and you get no published thickness, no named base metal and no warranty term for the saving.
- The one to skip: Missoma. A $140 hoop with nothing published behind it. Last on the Ledger at 14.0 points.

The Ledger: six demi-fine jewelry brands scored on what they publish
Monica Vinader takes this on 87.5 of 100. Ana Luisa is second on 49.5. That gap is not close, and it is not about design.
Read what this Ledger measures before you argue with it. It scores what each brand commits to in public: the thickness of the gold, the length of the warranty, whether the warranty names the failure mode this category actually has, whether anything can be done once the gold goes, and whether the list price is the real price. It does not score how the jewelry looks, how the clasp feels, or whether the design is any good. A brand can make lovely earrings and publish nothing. Missoma may well do exactly that.
How Are These Weighting Criteria Chosen?
Five axes, weighted for this matchup. The reason for each weight, in a sentence:
- Gold Layer Disclosed — weight 25. Thickness is the only number available before purchase that has any bearing on how long the color lasts, so a brand that withholds it is asking you to buy blind.
- Warranty Term Published — weight 25. A term you can read before paying is the difference between a promise and a mood.
- Plating Wear Named in the Warranty — weight 20. Gold-plated jewelry fails by the gold coming off, so a warranty that covers everything except that covers the wrong thing.
- Restoration Path — weight 15. Worth real points but not top billing, because most buyers of a $100 pair of hoops will replace rather than restore.
- Price You Actually Pay — weight 15. A list price nobody pays makes every other calculation on this page wobble, which is a problem, though a smaller one than a gold layer of unknown depth.
Each brand scores 0 to 10 per axis. Weighted points are the score multiplied by the weight and divided by ten. Maximum 100.
How Do Demi-Fine Jewelry Brands Score on Gold Layer and Warranty?
| Axis (weight) | Monica Vinader | Ana Luisa | Mejuri | Astrid & Miyu | gorjana | Missoma |
|---|---|---|---|---|---|---|
| Gold Layer Disclosed (25) What the brand publishes | 10 At least 2.5 microns of 18k, stated on the product page | 2 No micron figure; help center names brass as the base for most pieces | 10 2.5 microns of 18k over sterling silver, stated on the materials page | 3 No micron figure; discloses both recycled sterling silver and plated brass | 1 No micron figure, no base metal named on the FAQ or care guide | 2 No micron figure on product, help, terms or returns pages |
| Warranty Term Published (25) | 10 5 years | 7 2 years | 1 A claims process, no duration | 5 1 year | 0 None stated | 0 None stated |
| Plating Wear Named (20) | 6 Re-plating offered; the warranty pages do not say whether color loss falls inside the 5 years | 9 Warranty covers tarnishing, water damage and breakage by name | 1 No term, so no window to check | 3 Excluded as wear and tear except a significant issue inside 3 months | 0 No warranty term to name anything in | 0 No warranty term to name anything in |
How Do Demi-Fine Jewelry Brands Score on Restoration and Price?
| Axis (weight) | Monica Vinader | Ana Luisa | Mejuri | Astrid & Miyu | gorjana | Missoma |
|---|---|---|---|---|---|---|
| Restoration Path (15) | 9 Will re-plate vermeil that loses color; lifetime repairs for an unstated fee | 3 States plainly it cannot repair; one-time replacement or store credit | 3 Replacement or store credit on approved claims; refinishing sits inside a separately purchased protection plan | 1 Help center says plating wear cannot be resolved by cleaning; no re-plating offered | 2 Free repair, fine jewelry only — the plated range is excluded | 0 Nothing published |
| Price You Actually Pay (15) | 8 List was list on the pages checked | 3 Member price shown beside list; sitewide spend-and-save promo running | 8 List was list on the pages checked | 8 List was list on the pages checked | 8 No crossed-out prices on the hoops range | 6 List was list, with a standing first-order discount banner |
Now the tally. Score times weight, divided by ten, added up.
| Rank | Brand | Gold Layer (×2.5) | Warranty Term (×2.5) | Plating Named (×2.0) | Restoration (×1.5) | Real Price (×1.5) | Total / 100 |
|---|---|---|---|---|---|---|---|
| 1 | Monica Vinader | 25.0 | 25.0 | 12.0 | 13.5 | 12.0 | 87.5 |
| 2 | Ana Luisa | 5.0 | 17.5 | 18.0 | 4.5 | 4.5 | 49.5 |
| 3 | Mejuri | 25.0 | 2.5 | 2.0 | 4.5 | 12.0 | 46.0 |
| 4 | Astrid & Miyu | 7.5 | 12.5 | 6.0 | 1.5 | 12.0 | 39.5 |
| 5 | gorjana | 2.5 | 0.0 | 0.0 | 3.0 | 12.0 | 17.5 |
| 6 | Missoma | 5.0 | 0.0 | 0.0 | 0.0 | 9.0 | 14.0 |
How Do the Weighted Scores Compare?
Disagree with a weight? Re-run the tally. If you think a repair service matters more than a printed micron figure, push Restoration to 25 and drop Gold Layer to 15, and Monica Vinader’s lead widens rather than shrinks. If you think the micron figure is the only thing that matters, move five points from Plating Named to Gold Layer and Mejuri jumps past Ana Luisa. That second scenario is worked out in full further down, because it is the one weight change that actually reorders the table.
What does not move is the bottom. Missoma finishes last at 14.0 under every weighting I tried, for the plain reason that four of the five axes have nothing to score.
Cost Per Warranted Year for These Demi-Fine Jewelry Brands
Ana Luisa is cheapest at $42.50 per warranted year. Monica Vinader costs $44.00. The gap is $1.50, on pieces $135 apart in price.
To make the arithmetic honest I needed one comparable item per brand, so I used each brand’s everyday plated or vermeil hoop earring. Sizes are not identical across the six and I am not pretending they are: the Missoma pair priced here is a small, while Monica Vinader’s and Mejuri’s are mediums. Prices are list, in US dollars, read from each brand’s own product page on 29 August 2026.
What Does Each Demi-Fine Jewelry Brand Cost Per Warranted Year?
Prices are approximate, current as of publication, and change frequently — confirm the latest price with the retailer before buying.
| Brand | Piece priced | Metal as the brand describes it | Price (29 Aug 2026) | Warranty years | Arithmetic | Per warranted year |
|---|---|---|---|---|---|---|
| Ana Luisa | Abby Hoop Earrings | 14k gold plated | $85 list ($72.25 for members) | 2 | 85 ÷ 2 | $42.50 |
| Monica Vinader | Deia Medium Hoop Earrings | 18k gold vermeil, at least 2.5 microns on 925 sterling silver | $220 | 5 | 220 ÷ 5 | $44.00 |
| Astrid & Miyu | Molten Hoops in Gold | 18k gold plated recycled sterling silver | $125 | 1 | 125 ÷ 1 | $125.00 |
| Mejuri | Tube Medium Hoops | 18k gold vermeil, 2.5 microns on recycled sterling silver | $118 | none published | — | Cannot be computed |
| gorjana | Lou Hoops | 18K gold plated | $70 | none published | — | Cannot be computed |
| Missoma | Classic Small Hoop Earrings | 18k gold plated | $140 | none published | — | Cannot be computed |
Three rows say cannot be computed. That is not a formatting failure. It is the finding. There is no denominator because Mejuri, gorjana and Missoma have not published one, and a warranty with no stated end is not generosity, it is an absence of writing.
Mejuri’s own warranty FAQ describes how to file a claim, what happens when a claim is approved, and that using a third-party repair service voids the warranty. It never says for how long any of that applies. gorjana’s FAQ covers a 30-day return window on unworn items and a free repair service restricted to its fine jewelry, and states no warranty period. Missoma’s US returns page gives 90 days on unworn items and its terms and conditions carry no jewelry warranty period at all.
Plating Cover Cost Per Year for Demi-Fine Jewelry Brands
Astrid & Miyu costs $500.00 per year of plating cover. That is the highest number on this page and it comes out of the brand’s own policy text, not out of anything I assumed.
The previous table used the headline warranty. This one uses the window in which a plating complaint will actually be entertained, which is a different number for one brand and the same number for the rest. Astrid & Miyu’s warranty policy covers all jewelry for one year, then lists under exclusions: general wear and tear, including plating wear, unless a significant issue occurs within three months of purchase. Three months is a quarter of a year. So the denominator is 0.25, not 1.
Plating Cover Windows for These Demi-Fine Jewelry Brands
| Brand | Window in which plating wear is covered | Years | Arithmetic | Per year of plating cover |
|---|---|---|---|---|
| Ana Luisa | 2 years — the warranty names tarnishing explicitly | 2.0 | 85 ÷ 2 | $42.50 |
| Monica Vinader | 5 years, if color loss counts as a warranty matter — Monica Vinader does not say either way, and separately offers to re-plate | 5.0 | 220 ÷ 5 | $44.00 |
| Astrid & Miyu | 3 months, and only for a significant issue | 0.25 | 125 ÷ 0.25 | $500.00 |
| Mejuri | No published term | — | — | Cannot be computed |
| gorjana | No published term | — | — | Cannot be computed |
| Missoma | No published term | — | — | Cannot be computed |
Twelve times. That is the multiple between Ana Luisa’s $42.50 and Astrid & Miyu’s $500.00, and it exists entirely because one brand wrote tarnishing into the covered list and the other wrote plating wear into the excluded list. Same product category. Same failure mode. Opposite paragraph.
Astrid & Miyu is not being sneaky about this, to be fair to them. The exclusion is written in plain English in the policy where you would expect to find it, and a separate help article says outright that plating wear cannot be resolved through cleaning because the plated surface layer has gradually worn away. That is a more candid description of how this product fails than four of the other five brands manage. Candor and coverage are separate things.
Cost Per Published Micron for These Demi-Fine Jewelry Brands
Mejuri costs $47.20 per published micron. Monica Vinader costs $88.00. Those are the only two figures in this section, because the other four brands publish no micron number for anyone to divide by.
| Brand | Published gold thickness | Where the brand publishes it | Price | Arithmetic | Per micron |
|---|---|---|---|---|---|
| Mejuri | 2.5 microns of 18k over sterling silver | Materials page | $118 | 118 ÷ 2.5 | $47.20 |
| Monica Vinader | At least 2.5 microns of 18k over 925 sterling silver | The individual product page | $220 | 220 ÷ 2.5 | $88.00 |
| Ana Luisa | Not published | — | $85 | — | No figure to divide by |
| Astrid & Miyu | Not published | — | $125 | — | No figure to divide by |
| gorjana | Not published | — | $70 | — | No figure to divide by |
| Missoma | Not published | — | $140 | — | No figure to divide by |
Note what this does to the assumption that price signals substance. Mejuri’s $118 hoop and Monica Vinader’s $220 hoop carry the same stated 2.5 microns. Missoma’s $140 hoop sits between them in price with no stated thickness at all. Price and published gold depth do not track across these six. If you are paying more expecting more gold, ask the brand for the number, because on four of these six sites the number is not there to find.
Monica Vinader still earns the higher price on the other axes. It just does not earn it here.
Claims Check: Marketing Claims From Demi-Fine Jewelry Brands
One claim on this list survives contact with independent testing. The rest range from half-right to unfalsifiable. Companies don’t exactly lie. They just measure things whichever way makes them look best, and sometimes they measure nothing and say a word instead.
Which Demi-Fine Jewelry Brand Claims Are Mostly Accurate?
| The claim | Who makes it | What the record shows | Verdict |
|---|---|---|---|
| A 2.5-micron layer of gold, compared to the industry’s 0.5-micron minimum | Mejuri, materials page | Under 16 CFR 23.3(c), the federal floor for calling something Gold Electroplate is 0.175 microns, and Heavy Gold Electroplate requires 2.5 microns. No US rule sets a 0.5-micron minimum. | Half true. The 2.5 figure is real and generous. The benchmark it is measured against is not a standard. |
| Gold vermeil requires a sterling silver base, a minimum of 10k, and a gold layer at least 2.5 microns thick | Ana Luisa, gold vermeil explainer | Matches 16 CFR 23.4(b) word for word in substance. Ana Luisa’s own help center states that the majority of its jewelry is 14k gold or rhodium plated with a base metal of brass. | Correct, and not about most of the product. A brass base cannot be vermeil at any thickness. |
| Tarnish-Free, Water-Resistant | Ana Luisa, product pages | Reviewed, part of the USA Today network, published a two-month wear test by senior editor Isabelle Kagan in August 2024 covering five Ana Luisa pieces worn day in and day out including in the shower, on a run, on a hike and while swimming. Her conclusion was that the no-tarnish claim held up. | Held up. The only claim on this page tested by a named independent publication under stated conditions. |
Which Demi-Fine Jewelry Brand Warranty Claim Holds Up Best?
| The claim | Who makes it | What the record shows | Verdict |
|---|---|---|---|
| 5-Year Warranty and Lifetime Repairs | Monica Vinader, quality promise page | Monica Vinader’s own pages say the 5-year warranty covers every piece free of charge, that the lifetime repair service runs for a small fee, and that vermeil losing its color will be re-plated. No fee amount appears on either page. | True, and the only re-plating offer of the six. The price of the thing that makes it the best offer here is not published. |
Which Demi-Fine Jewelry Brand Claims Don’t Hold Up?
| The claim | Who makes it | What the record shows | Verdict |
|---|---|---|---|
| All A&M jewellery is covered by a 1-year warranty | Astrid & Miyu, warranty policy | The same policy excludes general wear and tear including plating wear, unless a significant issue occurs within three months of purchase. A separate help article states plating wear cannot be resolved through cleaning. | One year for the metal. Three months for the gold. Both sentences are in the same document. |
| Our fashion 18K gold-plated jewelry is protected with an anti-tarnish barrier | gorjana, care guide | gorjana publishes no micron figure, names no base metal on its FAQ or care guide, states no warranty period, and restricts its free repair service to gorjana Fine Jewelry pieces. | Unfalsifiable. There is no number, no term and no remedy attached to it. |
| Product titles that distinguish 18k gold plated from 18k gold vermeil | Missoma, product pages | The distinction implies a sterling silver base on the vermeil range, which would be correct. No micron figure and no warranty duration appeared on Missoma’s US product pages, help pages, terms and conditions or returns page. | Nothing to check. The word is doing all of the work. |
What Does the Ana Luisa Result Mean for Demi-Fine Jewelry Brands?
The Ana Luisa row matters more than the others, and not because it is flattering. Ana Luisa scores 2 out of 10 on the thickness axis and gets beaten badly on disclosure. Its actual product still passed two months of showering, running, hiking and swimming in the hands of a named editor at a named publication. Disclosure and performance are different questions, and this page can only score one of them properly. Bear that in mind before treating the Ledger as a verdict on quality.
The Tie-Breaker Between Two Demi-Fine Jewelry Brands
Ana Luisa takes second on 49.5. Mejuri takes third on 46.0. A 3.5-point gap on a 100-point scale is inside the margin of one reasonable disagreement, so second place here is a genuine tie in everything but the arithmetic.
Watch it flip. Move five weight points from Plating Wear Named (20 down to 15) into Gold Layer Disclosed (25 up to 30), which is what you would do if you believe a thick, published gold layer prevents the problem that a warranty only pays out on:
- Ana Luisa recalculated: (2 × 3.0) + (7 × 2.5) + (9 × 1.5) + (3 × 1.5) + (3 × 1.5) = 6.0 + 17.5 + 13.5 + 4.5 + 4.5 = 46.0
- Mejuri recalculated: (10 × 3.0) + (1 × 2.5) + (1 × 1.5) + (3 × 1.5) + (8 × 1.5) = 30.0 + 2.5 + 1.5 + 4.5 + 12.0 = 50.5
One weight change and Mejuri is second by 4.5. Monica Vinader still wins that version on 89.5, which is why the top of this table is not a tie and the middle is.
Which of These Demi-Fine Jewelry Brands Would I Buy?
After enough humid summers watching cheap plating go first at the clasp, I’d spend my money on Mejuri, since its 2.5 published microns beat a warranty I can’t test until something breaks. 2.5 microns of 18k over sterling silver at $118 is the most gold anyone here will commit to per dollar. A published thickness is a fact I can check today, while a two-year warranty is a promise I have to test by having something go wrong first. Ana Luisa’s warranty is better written. Mejuri’s product is better documented.
Take the other side if you want the failure mode named in a contract rather than the material named on a spec page. That is a defensible read of the same evidence, which is more than can be said for the bottom two.
What Vermeil Legally Means for Demi-Fine Jewelry Brands
Vermeil is not a marketing adjective in the United States. It is a defined term with three conditions, and a piece that misses any one of them cannot carry the name.
Under 16 CFR § 23.4(b), a product may be described as vermeil if it consists of a base of sterling silver coated or plated on all significant surfaces with gold, or gold alloy of not less than 10 karat fineness, that is of reasonable durability and a minimum thickness throughout equivalent to two and one half microns of fine gold. Three conditions. Sterling silver underneath. At least 10 karat. At least 2.5 microns.
Compare that to ordinary plating. 16 CFR § 23.3(c) sets the floor for marking something Gold Electroplate at a minimum thickness equivalent to 0.175 microns, and reserves the term Heavy Gold Electroplate for 2.5 microns. So the legal gap between the thinnest thing that may legally be called gold electroplate and the thinnest thing that may legally be called vermeil is roughly fourteen to one.
Why Does the Base Metal Matter for Demi-Fine Jewelry Brands?
The base metal rule is the one that catches people. A brass base disqualifies a piece from being vermeil at any thickness whatsoever. You could plate brass with ten microns of 24k gold and it still would not be vermeil, because vermeil is a statement about what is underneath as much as what is on top. Section 23.4 goes further and treats it as deceptive to call something vermeil where the sterling silver has been covered with a base metal that is then plated with gold, unless that intermediate layer is disclosed.
These Guides were last given a full revision by the Federal Trade Commission in July 2018, in a package the agency said covered, among other things, the surface application of precious metals. They are guides rather than a statute, which means they describe what the FTC considers deceptive rather than carrying their own criminal penalty. In practice they set the vocabulary the whole industry markets in.
Line the six brands up against that vocabulary and the sorting is instant. Mejuri and Monica Vinader use the word vermeil and publish a 2.5-micron figure to back it. Missoma uses the word on part of its range and publishes no figure. Astrid & Miyu avoids the word entirely and instead discloses two base metals, recycled sterling silver on some pieces and plated brass on others, which is more useful than it first looks. gorjana says 18K gold plated and stops. Ana Luisa explains the vermeil standard on one page and tells you on another that the majority of its jewelry uses a brass base, which is a strange pair of sentences to publish on the same website.
Which Demi-Fine Jewelry Brands Are Wrong for You?
Winning a Ledger does not make a brand right for you. Here is the buyer each of the six is a bad purchase for.
Monica Vinader
Skip this if you are buying one pair of everyday hoops and nothing else. At $220 for the Deia Medium Hoop Earrings you are paying $88.00 per published micron against Mejuri’s $47.20 for an identical stated thickness, and the five-year warranty plus re-plating offer only earn their premium if you own several pieces and intend to keep them. The re-plating fee is also unpublished, so the strongest argument for the brand comes with a blank where a number should be.
Mejuri
Skip this if you want a term you can hold someone to. Mejuri publishes the best thickness-per-dollar here and no warranty duration whatsoever, which is an odd combination: confident about the material, silent about the commitment. If your buying decision runs through the returns and warranty page rather than the materials page, this brand will frustrate you.
Ana Luisa
Skip this if a brass base is a dealbreaker, or if you want your jewelry repaired rather than swapped. Ana Luisa states plainly that it is not able to repair broken or damaged jewelry and offers a one-time replacement or store credit instead. Returns inside the 30-day window also carry a fee that varies by product and return method. And treat the list price as a starting position rather than a price — the Abby Hoop Earrings show $85 list against $72.25 for members, with a sitewide spend-and-save promotion running on top.
Astrid & Miyu
Skip this if you expect the plating to be covered. Three months, and only for a significant issue, on a $125 pair of hoops. That is $500.00 per year of plating cover, the worst number on this page.
gorjana
Skip this if you are buying the plated range and expecting the repair service to apply to it. The free repair service covers gorjana Fine Jewelry pieces, which is the solid 14K and 18K gold line, not the 18K gold plated pieces most people come to the brand for. At $70 the Lou Hoops are the cheapest of the six pairs priced here by $15, and $70 is a fair price for a pair of hoops you treat as consumable. Just do not build a plan around them lasting.
Missoma
Skip this if you want anything checkable before you pay. $140 for the Classic Small Hoop Earrings, no published micron figure, no published warranty term, no published repair or re-plating route. The 90-day return window on unworn items is genuinely the longest of the six and it is the only concrete commitment I found. Missoma is the loser of this comparison and the margin is not close.
Questions About Demi-Fine Jewelry Brands, Answered
What Does Gold Vermeil Mean for Demi-Fine Jewelry Brands?
Under 16 CFR 23.4(b), gold vermeil means three things at once: a base of sterling silver, a gold or gold alloy coating of not less than 10 karat fineness, and a minimum thickness throughout equivalent to two and one half microns of fine gold. Miss any one condition and the piece cannot be called vermeil.
Is gold vermeil the same as gold plated?
No, and the gap is large. 16 CFR 23.3(c) allows the term gold electroplate at a minimum thickness of 0.175 microns, while vermeil requires 2.5 microns over sterling silver. That is roughly fourteen times the gold, plus a specified base metal. Gold plated can legally mean almost nothing about what is underneath.
Can Demi-Fine Jewelry Brands Use a Brass Base and Call It Vermeil?
No. 16 CFR 23.4(b) requires a base of sterling silver, so no thickness of gold rescues a brass core. The regulation also treats it as deceptive to call a piece vermeil when sterling silver has been covered with a base metal that is then gold plated, unless that intermediate layer is disclosed to the buyer.
Which Demi-Fine Jewelry Brands Publish a Gold Thickness Figure?
Two. Mejuri states 2.5 microns of 18k gold over sterling silver on its materials page. Monica Vinader states at least 2.5 microns of 18k gold over 925 sterling silver on individual product pages, which is the more useful placement. Ana Luisa, Astrid and Miyu, gorjana and Missoma publish no micron figure on the pages a buyer would check.
Which demi-fine brand will re-plate its own jewelry?
Only Monica Vinader, of these six. Monica Vinader states that vermeil losing its color over time will be re-plated, alongside a five-year warranty and a lifetime repair service described as carrying a small fee. That fee is never quantified anywhere on the warranty pages, so the size of the benefit is unknown.
Does Mejuri publish a warranty length?
No. Mejuri’s warranty FAQ explains how to submit a claim, states that an approved claim results in a replacement or store credit, and warns that using a third-party repair service voids the warranty. No duration in months or years appears on that page or on the general FAQ page. The stated return window is 30 days.
How long does Astrid and Miyu cover plating wear?
Three months, not one year. Astrid and Miyu covers all jewelry with a one-year warranty, then excludes general wear and tear including plating wear unless a significant issue occurs within three months of purchase. On a 125 dollar pair of hoops that works out to 500 dollars per year of plating cover, against 42.50 for Ana Luisa.
Do Any Demi-Fine Jewelry Brands Name Tarnishing in Their Warranty?
One does. Ana Luisa’s two-year warranty covers tarnishing, water damage and breakage by name, with a remedy of one-time replacement or store credit rather than repair. Astrid and Miyu names plating wear only to exclude it after three months. Monica Vinader, Mejuri, gorjana and Missoma do not address tarnishing in warranty terms at all.
Have Any Demi-Fine Jewelry Brands Been Tested for Tarnishing?
Yes, one. Reviewed, part of the USA Today network, ran a two-month wear test of five Ana Luisa pieces by senior editor Isabelle Kagan, published in August 2024, covering daily wear in the shower, on a run, on a hike and while swimming. Her verdict was that the tarnish-free claim held up. No comparable independent test of the other five surfaced.
How Long Does Gold Plating Last on Demi-Fine Jewelry Brands?
Nobody in this group publishes a figure, and I am not going to invent one. 16 CFR Part 23 sets a thickness floor, not a lifespan. None of these six states an expected wear life, and no independent laboratory test of their plating durability surfaced in research. Thickness is the only pre-purchase proxy available, which is why two brands publishing it matters.
Do Pricier Demi-Fine Jewelry Brands Have Thicker Gold?
Not across these six. Mejuri’s 118 dollar hoop and Monica Vinader’s 220 dollar hoop both state 2.5 microns, which is 47.20 dollars per micron against 88.00 dollars per micron. Missoma’s 140 dollar hoop sits between the two in price and publishes no thickness at all. Price sorts these brands. Published gold depth does not.
Four Things to Check on Demi-Fine Jewelry Brands’ Pages
This comparison covers six brands. The method behind it works on any of them, and it takes about four minutes on a phone.
- Find the micron figure. Not the karat. The karat tells you the purity of a layer whose depth you do not know yet.
- Find the base metal. Sterling silver and brass are different purchases, and a brand that says vermeil is telling you sterling silver by law.
- Find the warranty duration. If the page describes a claims process without a number of months attached, there is no term.
- Find the word plating inside the warranty. Check whether it appears in the covered list or the excluded list. That single placement swung this page’s numbers by a factor of twelve.
Monica Vinader wins on 87.5 because it survives all four checks. Missoma finishes on 14.0 because it fails three of them and offers a 90-day return window instead.
If a brand publishes a re-plating fee, or a micron figure I could not find, send it over. I will re-run the tally and say so on this page.
If you already own something from one of these six, our comparison of ultrasonic cleaners, steam cleaners and a plain dish-soap soak covers which of the three is safe on plated jewelry. Two of them are not, and the brands here mostly do not warn you. More side-by-side scoring lives on our jewelry page.
