What VVS1 Actually Means on Moissanite
Nearly every moissanite listing says "VVS1 clarity". Almost none of them explain what it means — or that on moissanite it is close to meaningless as a quality signal.
Where the term comes from
VVS1 is a diamond clarity grade. On the GIA scale:
- FL / IF — flawless / internally flawless
- VVS1 / VVS2 — very very slightly included; inclusions are extremely difficult to see even at 10× magnification
- VS1 / VS2 — very slightly included; minor inclusions visible at 10×
- SI1 / SI2 — slightly included; noticeable at 10×
- I1 / I2 / I3 — included; visible to the naked eye
The scale exists because natural diamonds form under geological conditions that trap other minerals inside them. Clarity is scarce and variable, so grading it matters.
Why it does not apply to moissanite the same way
Moissanite is grown, not mined. The growth process produces a crystal with essentially no inclusions at jewellery grade. Nearly all moissanite on the market is eye-clean and clean under magnification.
So when a listing says "VVS1", it is not distinguishing that stone from a worse one. It is describing the baseline for the material. You will not find a widely-sold "SI1 moissanite" because the material does not come that way.
Practical consequence: VVS1 is not a reason to pay more. It is a description, not a differentiator.
What actually varies in moissanite
Three things, and they matter far more than the clarity grade:
1. Colour
Moissanite is graded D to near-colourless. Lower grades carry a visible warm or yellow cast, most obvious next to a whiter stone or against white metal.
- D — colourless, no tint
- GH — very slightly warm, visible in comparison
- IJ — noticeable warm cast
Our stock is D colour. This is the grade that actually matters and the one to ask about.
2. Cut quality
The single biggest determinant of how a moissanite looks. Two stones with identical colour and clarity can look completely different:
- Proportions — table size, crown angle, pavilion depth. Wrong proportions produce a window (see-through middle) or a fisheye.
- Symmetry — facet alignment. Asymmetry is visible as uneven light return.
- Polish — surface finish. Poor polish means duller light return.
- Bow tie — in elongated cuts, the severity of the dark central band is a cut-quality issue.
Cut quality is rarely stated as a grade on moissanite listings, which is a real problem. The practical substitute: ask for a video of the specific stone, face-on, in diffuse light.
3. Cut style
Whether it is a brilliant cut (round, oval, radiant) or a step cut (emerald, asscher) changes light behaviour entirely. Step cuts show doubling in moissanite above about 1.5ct.
What a GRA certificate actually states
GRA (Global Gemological Research Academy) issues certificates for moissanite. A typical GRA report covers:
- Stone type (moissanite) — explicitly named
- Dimensions in millimetres
- Carat or gram weight
- Colour grade
- Shape and cut style
- A certificate number
What it does not state, because it does not apply:
- Clarity grades on the diamond scale
- Fluorescence
- Polish and symmetry grades
- Cut grade
If a moissanite certificate shows a full diamond-style clarity and cut grading report, ask which laboratory issued it and check the number on their site. GRA does not produce that format.
The red flags
- "GIA certified moissanite" — GIA does not grade moissanite. There is no fourth option: the certificate is for a different stone, or does not exist.
- "FL flawless moissanite" — a meaningless upgrade claim on a material that is uniformly clean.
- Clarity used as a price justification — "VVS1, hence the premium". Colour and cut justify premium. Clarity does not.
- No certificate for a stone over 1ct — moissanite over 1ct should have GRA.
What to ask instead of "what clarity"
Four questions that actually predict how the stone will look:
- What colour grade? D is what you want unless you specifically like warmth.
- What is the length-to-width ratio? For any non-round shape, this determines the look.
- Can you send a video of this specific stone in daylight? Not a studio photo on white — those are lit to flatter.
- Does the certificate number match the stone? Check it against GRA's own lookup.
What we state
Our moissanite is D colour, and every piece ships with a GRA certificate matched to that specific stone, packed in the box rather than emailed separately. The certificate states stone type, dimensions, weight and colour.
We do not market clarity as a differentiator, because on moissanite it is not one. If you want to know what to compare instead, ask us about colour grade and cut proportions for the specific piece you are considering.
