Short version: moissanite is no longer sold as a diamond substitute, it is its own category. Around 66 per cent of US buyers are open to lab created stones and 52 per cent prefer moissanite for bridal. The stone is 9.25 on the Mohs scale and will outlive the piece it sits in, which is the problem: most moissanite is set in plated metal that wears through in a year. That mismatch is where your returns come from.
What actually changed
For years moissanite sold on price. You bought it because a diamond was out of reach, and everyone in the shop knew it. That has gone.
The numbers moved first. The Knot's annual study found more than 18 per cent of engagement rings bought in 2024 had a non diamond centre stone. In 2019 it was about 8 per cent. Industry analysis for 2026 puts roughly two thirds of US buyers as open to lab created stones, and just over half as actively wanting moissanite for bridal.
Then the culture moved. In early 2026 hip hop artists started openly wearing moissanite watches and pendants instead of VVS diamonds. Once people who can clearly afford diamonds pick something else, nobody has to explain their choice any more.
The customer who walks in today is not asking whether moissanite is legitimate. They want to know which cut, which setting and which metal.
What is selling
| What | Share of demand |
|---|---|
| Round brilliant cut | About 43% |
| Minimalist everyday pieces, thin bracelets and small studs | About 41% |
| Moissanite paired with mixed metals, silver with gold or rose accents | About 33% of fashion buyers |
That last line is the one most people get wrong. The growth is not in big statement rings. It is in small pieces somebody wears every day, so the piece gets knocked about, washed, slept in, and judged on how it looks a year later.
On margin, one large US wholesaler puts retailer margins at 60 to 75 per cent. That is their number, not an independent one, but the logic holds. A moissanite looks far more expensive than it costs, so what the customer sees has very little to do with what you paid.
The part that lets it down
Moissanite is 9.25 on the Mohs scale. It will look the same in twenty years. Now look at what it usually gets set in.
- Plated brass. Buyers worked this out and will not take it any more. Solid 925 is the floor now, not something to boast about.
- Rhodium plated sterling. Better, but the plating is what makes it white, and plating wears off. It goes first at the shank and the prong tips, which are the two places a customer actually looks.
- Light prongs. A soft mount with a hard stone bends, the stone moves, and it comes back to you.
A stone that outlives its setting is a return waiting to happen. Nobody comes back and blames the plating. They blame the piece, and they blame you.
Why Argentium suits this stone
No plating, so nothing wears off. Argentium 960 is 96 per cent silver and it is white on its own, so the finish the customer buys is the metal itself.
It can be hardened. Argentium heat hardens, and the right time to do it is after casting and before the stone is set. A harder mount holds a bigger stone without the prongs easing open.
It resists tarnish. Germanium in the alloy forms a protective layer instead of the copper sulphide that blackens sterling, which matters for a piece sitting in a case for six months before it sells.
No nickel. Argentium contains no nickel, which is the other reason cheap pieces come back.
One thing the bench has to know: Argentium is brittle while hot, so it must not be moved or quenched while red. Any workshop that uses it regularly already works that way.
What to ask a supplier
- What exactly is the metal, and is it plated. A vague answer means plated.
- Is the moissanite certified, and by whom.
- Are the mounts hardened before setting.
- What is the stone size tolerance. Mixed sizes in a pavé row is what makes a piece look cheap.
- Do the findings match the body metal, or are the earring posts plated base metal.
- Will they make your design, and will they resell it to someone else.
Frequently asked questions
Is moissanite worth stocking in 2026?
The demand is there. Industry analysis puts around 66 per cent of US jewelry buyers as open to lab created gemstones, and 52 per cent as preferring moissanite for bridal. The Knot's annual study found more than 18 per cent of engagement rings bought in 2024 had a non diamond centre stone, against roughly 8 per cent in 2019. What changed recently is cultural rather than economic: in early 2026 the switch by hip hop artists from diamonds to moissanite took the stone mainstream, which removed the last of the apology attached to buying it.
What metal should moissanite be set in?
Something that outlasts the stone. Moissanite is 9.25 on the Mohs scale and will look the same in twenty years. Plated brass will not, and plated sterling will wear through at the shank and the prong tips. That mismatch is where returns come from. Argentium 960 is 96 per cent silver and needs no plating at all, so there is nothing to wear off, and it can be heat hardened before setting so the prongs stay firm.
What sizes and cuts of moissanite sell best?
The round brilliant is still about 43 per cent of the market. Beyond that, the growth is in small, everyday pieces rather than statement rings, with minimalist daily wear around 41 per cent of demand, so thin single row bracelets and small studs. Around a third of fashion buyers want moissanite paired with mixed metals, silver with gold or rose accents.
What margin do retailers make on moissanite jewelry?
One large US wholesaler puts the range at 60 to 75 per cent for retailers, which is their figure rather than an independent one. The reason the margin is wide is that the stone is cheap relative to how large it looks, so the value the customer sees is not tied to what you paid.
Is moissanite the same as cubic zirconia?
No, and conflating the two is one reason cheap moissanite has a bad name. Moissanite is silicon carbide at 9.25 on the Mohs scale, harder than any common gemstone except diamond and corundum, and it does not cloud. Cubic zirconia is 8 to 8.5, softer, and it abrades and dulls with wear. Genuine moissanite also passes a standard diamond tester, which cubic zirconia does not.
Can moissanite be set in Argentium silver?
Yes, and it suits it. Argentium can be heat hardened after casting and before the stone goes in, which raises the hardness of the mount so prongs hold a larger stone without bending. The one thing a bench needs to respect is that Argentium is brittle when hot, so it should not be moved or quenched while red.
Why do cheap moissanite pieces look cheap?
It is rarely the stone. It is thin plating over brass, loose or uneven pavé, and prongs cut too light for the stone. Buyers have moved on from mystery alloys, and solid 925 or better is now the floor rather than a selling point.
