Updated September 2026: Charles & Colvard’s Chapter 11 filing, the June 2026 sale of its assets, and GIA’s October 2025 switch to Premium/Standard lab-grown grading are all re-verified against SEC filings. GIA’s own current pages confirm the same details. Moissanite and lab-grown diamond prices are checked against current retailer ranges.
The direct answer: a 1-carat moissanite runs about $550 and a 1-carat lab-grown diamond about $850, but price isn’t the only thing that changed this year. Charles & Colvard, the company that patented moissanite as a gem and still writes the “lifetime warranty” printed on most Forever One rings, filed Chapter 11 in March 2026 and sold its assets for $2.7 million in June — to a company that sells lab-grown diamonds. Lab-grown diamonds picked up their own asterisk the same year: GIA stopped giving them specific color and clarity grades in October 2025. Both are still real, durable, dramatically cheaper alternatives to a natural diamond. Neither is quite the same purchase it was a year ago.
I’ve spent enough afternoons in salt air and sunscreen to know a ring takes more abuse at the beach than in a jewelry store. Grit and salt find every setting eventually, so actual hardness matters more than how a stone photographs under store lighting. That’s the detail I look for past the marketing copy.
The Company Behind Forever One Moissanite Filed Chapter 11 This Year
Before the hardness numbers and the price tables, it’s worth checking whether the promises stamped on the box still mean what they say. On moissanite, at least one doesn’t — not because the stone changed, but because the company did.
Moissanite vs. Lab-Grown Diamond: Which Claims Hold Up?
| Claim | Where It’s Made | What the Record Shows | Verdict |
|---|---|---|---|
| Forever One moissanite is “backed by a lifetime warranty” | charlesandcolvard.com, current homepage | Charles & Colvard filed Chapter 11 on March 3, 2026. A bankruptcy court approved a $2.7 million sale of its assets to AJS Creations on June 25, 2026. AJS Creations owns the lab-grown diamond retailer Grown Brilliance. Neither the SEC filings nor the court order say anything about existing warranty claims. | Unconfirmed. The words are still on the site. No public filing states whether the new owner will honor a warranty the old one wrote. |
| A lab-grown diamond comes with “the same 4Cs grading as a natural diamond” | common phrasing across lab-grown diamond retail sites | GIA’s own newsroom confirms it retired specific color and clarity grades for lab-grown stones effective October 1, 2025. In their place are two descriptors: “Premium” or “Standard.” A stone that misses the bar for Standard gets no report at all. | No longer true, for a GIA report. IGI has kept issuing full letter-and-number grades for lab-grown stones. The detail still exists; you just have to know which lab’s report you’re holding. |
Moissanite vs. Lab-Grown Diamond: Which Claims Don’t?
| Claim | Where It’s Made | What the Record Shows | Verdict |
|---|---|---|---|
| Moissanite “looks exactly like a diamond” | widespread retailer and marketing copy | GIA’s own gemstone education describes moissanite as showing “more than twice the fire of diamond.” It also notes a visible double image of a stone’s back facets under magnification, the specific traits jewelers use to identify it as not-diamond. | Overstated. Close in a casual glance, not identical under a loupe or bright light. |
| A moissanite or lab-grown stone is “an investment” that “holds its value” | occasional retailer marketing, and a common buyer assumption | Neither has a functioning resale market. Trade publication JCK reported lab-grown diamond wholesale prices down 96% since 2018. One gem dealer told the outlet flatly that a client’s $25,000 lab-grown ring had “no resale value” beyond the metal setting. | False for both. Buy either one to wear, not to resell. |
The wattage-label problem this site usually finds in a comparison like this is a maker fudging a number. This one is different. The number on the moissanite warranty hasn’t changed, but the company standing behind it has been through bankruptcy court, and the new owner primarily sells the competing product.
GIA Stopped Giving Lab-Grown Diamonds Specific Grades in October 2025
GIA’s reasoning, from its own announcement, is arithmetic rather than skepticism. Laboratory-grown diamonds are grown to spec, not mined, so the vast majority land in a narrow band of color and clarity. Tom Moses, GIA’s executive vice president and chief laboratory and research officer, put a number on it. More than 95% of lab-grown diamonds entering the market fall into that narrow range. A grading scale built in the 1940s was made for one-of-a-kind mined stones, GIA argued. It doesn’t tell a buyer much when nearly every stone submitted lands in the same few boxes.
So as of October 1, 2025, a GIA report on a lab-grown diamond reads “Premium” or “Standard” — full stop, no VS1, no F-color, no cut grade spelled out. A stone that doesn’t clear the bar for Standard gets no report at all. That’s not true everywhere. IGI, the other major lab most retailers use for lab-grown stones, has kept issuing the full 4Cs: an individual color grade, an individual clarity grade, cut, polish and symmetry, the same format it always has. The detail GIA stepped back from didn’t disappear from the industry. It just moved to a different piece of paper. A buyer comparing two lab-grown diamonds side by side needs to know which lab wrote each report before “VS1” and “Premium” can be compared at all.
Moissanite gets no comparable independent report from either lab. What ships with a Charles & Colvard stone is the company’s own documentation, not a third-party grade.
The Ledger: Five Weighted Axes for Moissanite vs. Lab-Grown Diamond
Cost per carat is the reason most people look at either of these in the first place, so it carries real weight below. It just isn’t all of it. Here’s the full tally.
Moissanite vs. Lab-Grown Diamond: Hardness and Certification
| Axis (weight) | Moissanite | Lab-Grown Diamond |
|---|---|---|
| Hardness & daily wear (20) — Mohs scale, per GIA | 17 / 20 — 9.25 Mohs, genuinely durable for daily wear, second only to diamond among gems used this way | 20 / 20 — 10 Mohs, chemically and physically identical to a mined diamond |
| Certification rigor (20) — independent third-party grading available | 4 / 20 — no independent lab report; documentation comes from the maker itself | 14 / 20 — GIA gives Premium/Standard only since Oct. 2025; IGI still issues full specific grades |
Moissanite vs. Lab-Grown Diamond: Price and Reputation
| Axis (weight) | Moissanite | Lab-Grown Diamond |
|---|---|---|
| Price per carat (30) — cheaper scores higher, the heaviest axis since it’s the reason either exists as an option | 30 / 30 — about $550 for a 1-carat stone | 19 / 30 — about $850 for a 1-carat stone, roughly 55% more per carat |
| Classic diamond look, no visible tell (15) — per GIA’s own identification notes | 7 / 15 — higher dispersion produces visible rainbow flashes and double refraction under magnification, the trait jewelers use to spot it | 15 / 15 — optically and physically indistinguishable from a mined diamond, even under a loupe |
| Company stability behind the promise (15) — can the seller make good on its own paperwork | 3 / 15 — Charles & Colvard filed Chapter 11 in March 2026 and sold its assets for $2.7 million in June; warranty continuity is unaddressed in any public filing | 13 / 15 — established retailers (James Allen, Blue Nile, Brilliant Earth) are financially stable, though JCK-reported wholesale price collapse is a real pressure on the category generally |
| Total | 61 | 81 |
Lab-grown diamond takes the tally, and it earns most of the gap on certification, the no-tell brilliance axis, and the company-stability score — not on price, where moissanite wins outright. Weight price higher relative to the other four axes if a lifetime warranty from a company that isn’t in bankruptcy court matters less to you than the sticker. That’s a defensible thing to do, and moissanite closes most of the distance. Disagree with a weight? The inputs are all above. Re-run it with your own priorities.
What a Carat Costs: Moissanite vs. Lab-Grown Diamond
Both numbers come from current retailer ranges rather than one seller’s list price. Moissanite and lab-grown diamond both price on a range depending on cut and clarity tier. Here’s the arithmetic, and where natural diamond sits for comparison.
| Stone | Typical 1-Carat Price | Vs. Moissanite | Resale Market |
|---|---|---|---|
| Moissanite | ~$500–$600 (call it $550) | — | None found. Too inexpensive for a functioning secondary market to exist around it. |
| Lab-grown diamond | ~$600–$1,100 (call it $850) | About 55% more per carat | Wholesale value down 96% since 2018 per JCK; consumer resale is close to zero, per the same reporting |
| Natural diamond | $3,000–$8,000, sources disagree (Blue Nile says $3,000–$5,000; Draco Diamond’s 2026 survey says $5,000–$8,000) | 5 to 15 times more, depending which range you use | Some. Estimates online for dealer or auction resale range roughly 20% to 50% of original retail, but no trade or regulatory body publishes a standard figure. Treat any number you see quoted for this, including that range, as a rough estimate, not a fact. |
The moissanite-to-lab-grown gap is real but not huge in dollar terms — about $300 on a 1-carat stone. The gap to a natural diamond is the one that actually explains why this comparison exists at all. Even at the low end of the natural range, moissanite runs roughly 82% cheaper and lab-grown roughly 72% cheaper. At the high end, both discounts run past 85%.
Extra Fire Is Also the Reason a Jeweler Can Spot It
Moissanite’s higher refractive index isn’t marketing spin. It’s a real optical property, and it’s the reason some buyers actively prefer it. GIA’s own material describes moissanite as showing more brilliance than a diamond of the same cut. It also shows roughly double the fire, the rainbow-colored flashes as light splits. In a 1-carat stone under normal indoor light, most people won’t notice. Go up in size, or into direct sun, and the effect becomes obvious enough that GIA’s own materials mention a “disco ball” look in larger stones. It isn’t a flaw exactly, but it is a different look than a diamond makes. It’s also the reason a jeweler can identify moissanite without special equipment: viewed at an angle, the extra dispersion produces a faint double image of the stone’s own back facets.
Skip moissanite if you specifically want the classic, slightly cooler diamond sparkle. It would bother you if a stone read as more colorful under bright light. Skip lab-grown diamond if saving the extra $300 a carat matters more to you than an optical match to a mined stone. Also skip it if you want a GIA report that spells out an actual color and clarity grade, not just “Premium,” and you haven’t confirmed which lab your retailer uses.
Neither Stone Resells, But Only One Company Didn’t Survive
Buy either stone assuming it’s the ring you’ll wear, not an asset you’ll liquidate. That part of the math is settled and it’s the same for both. What’s different is what happens on the seller’s side of the transaction.
Charles & Colvard’s own site now carries a banner announcing the acquisition. The homepage still advertises the Forever One lifetime warranty in the same language it used before the filing. Executive Chairman Michael Levin’s statement at the time of the Chapter 11 filing said customers “can continue to shop with confidence.” It also said operations would proceed “without interruption.” That’s a company’s statement about itself during a bankruptcy proceeding, not an independent confirmation. It also predates the June sale to AJS Creations, whose CEO has said the plan is to “operate it as a standalone brand,” with no public statement so far about whether pre-sale warranty claims will be honored.
Lab-grown diamond retailers carry a different risk. None of the major sellers checked here are in bankruptcy. But the wholesale collapse JCK reported, a 96% decline since 2018 with a 26% drop in 2025 alone, is exactly the kind of pressure that put Charles & Colvard in Chapter 11 in the first place. That’s just one link up the supply chain from the retailer a buyer actually deals with.
Buy Lab-Grown If Certification and Continuity Matter More Than Price
After enough salt-air seasons to trust hardness over a warranty, lab-grown diamond is the one I’d point a friend toward: real Mohs parity, and a retailer that hasn’t been through bankruptcy court. The roughly $300-a-carat premium over moissanite buys most of that.
Moissanite is still the right buy if the $550 price tag itself is the deciding factor. It’s also the right buy if the extra fire is a feature to you rather than a tell. Just don’t count on the “lifetime” in Forever One’s warranty meaning what it meant before March 2026. Confirm directly with whoever is selling you the ring, in writing, what the new ownership actually honors.
