Where Does Moissanite Come From?

You found a stone that looks like a flawless diamond at a fraction of the price, and now you are asking the sensible question: what actually is it, and where does it come from? Is moissanite mined somewhere? Grown in a lab? Chipped out of a meteorite?

The short answer: every moissanite sold as jewelry today — including every stone we set — is lab-created. Natural moissanite exists, but only as microscopic crystals in meteorite fragments and a few rare rocks, far too small to cut. There is no moissanite mine anywhere on Earth. The stone in your jewelry is silicon carbide, grown on purpose in a controlled lab process — and that lab origin is exactly why it can be so clear, so colorless, and so reasonably priced.

That answer surprises people, usually in a good way. Here is the practical version of the story: how the mineral was discovered, why nature cannot supply it, how the stone in your jewelry is actually made, and what happens between the furnace and the finished piece.

The two-minute history

In 1893, the French chemist Henri Moissan — who would go on to win the Nobel Prize in Chemistry — was studying rock samples from the Canyon Diablo meteorite crater in Arizona. Inside them he found tiny, brilliantly sparkling crystals that he initially took for diamonds. They were not. Careful analysis showed they were silicon carbide, a compound of silicon and carbon that had never before been documented in nature. The new mineral was named moissanite in his honor.

The crystals themselves came from beyond Earth: silicon carbide forms around dying stars and rides here inside meteorites. It is a genuinely spectacular origin story, and we have told it in full — stars, craters, Nobel Prizes and all — in Where Does Moissanite Come From? The Space Gem Origin Story.

For a buyer, though, one detail matters more than all the romance: the crystals Moissan found were microscopic. Nobody has ever cut a wearable gemstone from natural moissanite. Which brings us to the practical question.

Why you cannot buy natural moissanite

Natural moissanite turns up in exactly two kinds of places. The first is meteorite fragments, like the Canyon Diablo material Moissan studied. The second is a small number of unusual terrestrial rocks, where it appears as microscopic grains — occasionally even as tiny inclusions trapped inside other minerals, including inside diamonds.

In every known case the crystals are minuscule and thinly scattered. There is no seam, no deposit, no concentration of the mineral anywhere that would justify a shovel, let alone a mine. That is the whole explanation for why jewelry moissanite is lab-grown: it is not a marketing choice, it is the only option there has ever been.

Two practical takeaways follow from that:

• "Natural moissanite" jewelry does not exist. If a seller claims their moissanite was mined, they are either confused or being dishonest — either way, shop elsewhere.
• Lab-created is not the budget version of moissanite. It is the only version. There is no "real" mined alternative sitting above it at a higher price.

Where jewelry moissanite actually comes from

Every gem-quality moissanite starts in a specialist crystal-growing facility, in equipment most people would describe as a very precise furnace.

The process is called thermal growth. A small seed crystal of silicon carbide goes into a sealed chamber with silicon and carbon source material. The chamber is heated to extreme temperatures under tightly controlled conditions, and vaporized material deposits onto the seed, building the crystal up one atomic layer at a time. It is slow — growing a rough crystal large and clean enough for faceting takes weeks — and it is unforgiving, which is why larger, fully colorless stones still cost more to produce than small ones.

Out of the chamber comes a rough crystal. From there, moissanite is treated exactly like any other gemstone: the rough is sawn, then cut and polished into finished stones, usually to calibrated millimeter sizes so they fit standard settings.

The commercial part of the story is short. Gem-quality moissanite first reached the market in 1998 through Charles & Colvard, the North Carolina company that developed the jewelry-grade growth process. For years it was the only producer; after the core patents expired in the mid-2010s, other manufacturers entered, cutting quality kept improving, and prices came down across the category. If you want the full economics, we broke them down in why is moissanite so cheap.

Why lab origin is a feature, not a flaw

Some shoppers hear "lab-created" and assume it means "lesser." With moissanite, the opposite is true — the lab is where its best qualities come from.

Purity you can order, not hope for

A mined stone is whatever the ground gives you, inclusions and tint included. A grown crystal is produced under controlled conditions, so producers can consistently reach high clarity and colorless-to-near-colorless grades. That is why VVS-clarity moissanite — eye-clean, with inclusions hard to find even under magnification — is the standard we set rather than a lucky find. We explain the grading in what VVS moissanite means.

A clean origin by default

No mining means none of the baggage that can come with it: no displaced earth, no murky multi-country supply chain, no question mark over where the stone came from. A lab-grown stone has a paper trail measured in weeks, not years.

A price set by production, not scarcity

Mined gems carry a rarity premium. Moissanite's price reflects what it costs to grow, cut, and set the stone — nothing more. That is why the same budget buys a dramatically bigger, cleaner look.

Still a real gemstone

Lab-created does not mean imitation. Moissanite is not pretending to be diamond; it is its own mineral with its own properties — including more fire (those colored flashes of light) than diamond, and a hardness of 9.25 on the Mohs scale, second only to diamond among common jewelry stones. It is the same silicon carbide found in meteorites, simply grown here. If you are weighing it against a lab-grown diamond — a different material at a different price — start with moissanite vs lab-grown diamond.

From furnace to finished piece

So how does a crystal grown in a chamber end up on your ear or around your neck? The chain is short:

1. Growth. The rough crystal is grown over weeks in a controlled chamber.
2. Cutting. Cutters facet the rough into round brilliants and fancy shapes, sized in millimeters. Moissanite is sold by millimeter rather than carat — a quirk that confuses everyone at first, so we untangled it in our mm-to-carat size guide.
3. Setting. A jeweler mounts each stone — in our case by hand, into solid .925 sterling silver.

That is the entire journey. Compare it with a mined stone's path through mine, sorting house, cutting operation, wholesalers, and dealers, and you can see why fewer hands also means a friendlier price.

At Jamilah Jewels, every piece uses VVS lab-grown moissanite set in .925 sterling silver — from the 4mm tennis chain, where dozens of stones sit shoulder to shoulder, to the 9mm and 12mm cluster earrings secured with screw-back fastenings, to the classic round-cut tennis bracelet. US shipping is free and insured, returns are open for 30 days, and every piece is covered by our Lifetime Guarantee.

How to know what you are buying

A quick honesty checklist, whoever you buy from:

• It should be described as lab-created. That is the correct description for all jewelry moissanite. "Natural" or "mined" moissanite is a red flag.
• Grades are producer specifications. Clarity and color descriptions on moissanite — ours included — come from the maker's growing standards rather than an independent per-stone certificate. That is normal for the category, and worth knowing.
• Expect millimeter sizing. Honest sellers quote mm, sometimes with a "diamond equivalent" carat figure for reference.
• It should test as moissanite. On a basic thermal diamond tester, moissanite reads like diamond; proper multi-testers identify it correctly. The full story is in does moissanite pass a diamond tester.
