Why SheerGem?

Quality you can verify. Promises we'll keep. Impact that lasts.

SheerGem exists because moissanite deserves a brand that takes it seriously.

For decades, moissanite has been treated as a budget option — a stand-in for diamond, sold on price, certified by no one in particular, set in plated metal, shipped in a generic box. The category trained people to expect less.

We started SheerGem to build the version of moissanite that doesn't ask you to settle on anything. Not the stone, not the setting, not what your purchase stands for. Below is what that means in practice — the four standards we hold every piece to, and the things we explicitly refuse to do.

Quality you can verify

Every SheerGem stone is graded against the SHEER standard by the International Gemological Institute — the same lab that certifies fine diamonds. Not by us. Not by an in-house gemologist. Not by a lab whose name nobody recognizes.

The SHEER standard tests five criteria: superior cut, hueless halation, exceptional fire and brilliance, ethically sustainable sourcing, and a risk-free guarantee. Less than 10% of the moissanite available today earns it.

Every stone ships with its IGI report. Every report is verifiable on IGI.org. The certificate isn't marketing — it's proof, issued by an independent third party with a century of gemological credibility behind it. If you've ever wondered whether a moissanite brand's quality claims are actually true, this is what verification looks like.

Promises we'll keep

The SheerPromise is six commitments we publish in advance and intend to honor for the life of every piece you buy from us.

A lifetime warranty against any damage. One-year returns with free shipping both ways. Lifetime trade-up credit at 110% toward a future piece. Lifetime cleaning and inspection. The 5% SheerLift contribution on every order. And our sustainability standards, kept by exception only when there are no exceptions.

We publish these in plain language because the jewelry industry has spent generations using fine print to limit liability. Our six commitments have no fine print to read. They mean what they say.

Impact that lasts

5% of every SheerGem order funds a microloan through Kiva to a woman building her own business. When she repays — and 96% of Kiva borrowers do — we lend the money again. To another woman. And again when she repays.

That mechanic is why we picked microloans over donations. A donation gets spent once. A microloan compounds. Your single purchase doesn't help one woman; it keeps lifting, forever.

SheerLift is the layer of the brand that doesn't get easier to copy as we grow. Quality can be matched if a competitor spends the money on certification. Promises can be matched if a competitor commits to them in writing. A sustained, named-borrower impact program with monthly transparency and quarterly reporting takes years of consistent commitment to build credibility for. We started it on day one because we intend to be doing it on day ten thousand.

A community we belong to

Every SheerGem customer is part of SheerHer — the community of women who chose this brand because they were done explaining themselves. Done explaining why they picked moissanite. Done explaining why they self-purchased instead of waiting. Done explaining why they cared about where things came from.

SheerHer is where featured borrower stories live, where we publish quarterly impact reports, and where customers post their pieces. It's a name for a thing that already existed: the woman who buys SheerGem isn't apologizing for her choices.

What we won't do

It's easier to know what a brand stands for from what it refuses than from what it claims.

We won't ship moissanite that doesn't meet the SHEER standard, even if it would lower our price. We won't issue our own certificates — only IGI's. We won't use plated or filled metal in any setting; only solid recycled gold and platinum. We won't run hype-driven engagement-ring marketing or compete on emotional pressure. We won't reduce the SheerLift percentage. We won't add fine print to the SheerPromise. We won't feature a borrower we haven't actually funded once we're past launch month.

And we won't pretend any of this is easy or finished. We're early. We're going to make mistakes. When we do, we'll fix them publicly and fast.

The short version

Most moissanite brands compete on price. We compete on standards — the gem we won't ship, the promise we won't soften, the impact we won't reduce.

SheerGem is the version of moissanite that doesn't ask you to settle on anything. That's the whole brand. Everything else is just the receipts.
