Moissanite 101
Why Moissanite Prices Vary So Much Between Sellers
With no grading system to anchor comparisons, price becomes the only visible number β and it is describing different things.

Short answer
Four causes, and the stone is rarely the main one. The metal β solid versus plated, and gram weight differences of two to one. Cut quality, which no laboratory grades in moissanite, so it varies enormously at the same stated size. Setting labour, which is most of the cost of any stone-set piece. And supply chain length. Because moissanite has no grading system to compare against, the only reliable comparisons are millimetres, gram weight and shank thickness.
Two listings, both β1 carat moissanite solitaire, 14K goldβ, at prices that differ by a factor of three. With diamonds you could at least compare reports. With moissanite there are none, so it is worth knowing what actually varies.
Cause one: the metal, almost always
The largest single variable, and the easiest to check.
A listing that says β14K goldβ is solid. One that says β14K gold over sterling silverβ, βgold filledβ, βvermeilβ or βgold platedβ is a layer over a base β a completely different object at a completely different cost. A number with no letters after it means solid.
Even between two solid 14K rings, the gram weight can differ two to one. Gold trades on a public daily market, so that is straightforwardly real money β and it is exactly the difference between a ring that holds its shape for thirty years and one that goes out of round in five.
Cause two is the one specific to moissanite: nobody grades the cut, so cut quality is invisible and varies enormously. With a diamond, an Excellent cut grade on a round is an independent assessment you can rely on. No laboratory grades moissanite cut, colour or clarity at all β the DβEβF and VVS descriptions on listings are seller assessments, not comparable between sellers. So two β6.5Β mm VVS D-colourβ stones can be a beautifully proportioned stone and a shallow one spread for size, at the same stated specification, and nothing written down distinguishes them. Cutting well costs more β more rough is sacrificed, more time is spent, and the optic axis has to be respected because moissanite is doubly refractive. That difference lands entirely in the price and nowhere in the description, which is why the only honest way to judge a moissanite is rotating video in ordinary light, and why a stone measuring larger than standard for its stated weight is a warning rather than a bargain.
Cause three: the setting labour
On anything with accent stones, this is most of the cost.
Each pavΓ© stone gets its own drilled seat and its own beads raised by hand under magnification. Forty stones is forty of those sequences. That is why the cost of a pavΓ© band is labour rather than stones, and why two visually similar rings can differ substantially depending on how carefully that work was done.
It is also why a level stone row is such a useful signal: it is the visible evidence of the invisible labour.
Cause four: how many hands it passed through
A great deal of online moissanite is drop-shipped β a seller lists a supplierβs catalogue and the order passes through to a workshop they have never visited. That model is legitimate, and it is why identical product photographs appear across dozens of unrelated shops.
But each party takes a margin, and none of them can change a shank thickness, send a side elevation, or photograph a piece part-finished. So a lower price sometimes means a shorter chain and sometimes means a thinner ring β and the way to tell is not the number but which questions each seller can answer.
Comparing properly, without grades
| Ask for | What it tells you |
|---|---|
| Metal, karat, solid or plated | Whether you are comparing like with like at all |
| Finished gram weight | How much metal you are actually buying |
| Centre stone in millimetres | Real size β carat figures are DEW, not weight |
| Shank width and thickness | Whether it survives decades |
| Accent count and size | The labour content |
| Rotating video, ordinary light | The only real evidence of cut quality |
Fill this in from both sellers. The pattern of blank cells is usually more informative than the answers.
When a lower price is genuinely fine
- Direct from a workshop, which removes several margins.
- A simpler setting β less labour, honestly less ring, and often a more durable one.
- Silver rather than gold, correctly described and bezel-set.
- A stone just under a standard size, which is the same visible ring for less.
- No showroom overheads.
Each of those is a real saving with nothing hidden. What distinguishes them from a thin ring is that a seller will name them when asked.
And when a higher price is not buying anything
Worth saying too. Because moissanite is not graded, there is no upper anchor β nothing stops a seller pricing an ordinary stone at several times its cost and describing it in impressive-sounding letters.
A higher price is not evidence of a better stone in a market with no grading. The same six questions apply in both directions: if an expensive listing cannot give you gram weight, shank thickness and video, the premium is not attached to anything you can verify.

Frequently asked questions
Why do moissanite rings vary so much in price?
Mostly the metal β solid versus plated, and gram weight differences of two to one between two solid rings. Then cut quality, which no laboratory grades in moissanite so it varies invisibly; setting labour, which is most of the cost of any stone-set piece; and how many parties the order passes through.
Does a more expensive moissanite mean a better stone?
Not necessarily. Because moissanite is not graded by any laboratory, there is no independent anchor, and nothing stops an ordinary stone being priced high and described in impressive letters. Ask the same questions in both directions: gram weight, shank thickness, millimetres and rotating video.
How can I judge moissanite quality with no grading report?
Rotating video in ordinary indoor light, not a lightbox: look for no permanently dark zone as it turns, a symmetrical outline, crisp facet junctions, and a table that is not oversized. Also check the measured millimetres β a stone larger than standard for its stated weight has been cut shallow to spread.
Are D-colour and VVS claims on moissanite reliable?
They are seller assessments rather than laboratory grades, so they are not comparable between sellers β no major laboratory grades moissanite on the diamond colour or clarity scales. Treat them as descriptive language and judge from video and measured dimensions instead.
Ask us the same six questions you ask everyone else.
Metal and karat, gram weight, centre millimetres, shank dimensions, accent count, and video in ordinary light.
