A boutique in Antwerp built its entire window display around emerald-cut moissanite. The first bulk order from a new supplier looked fine under showroom lights, but within a week the owner noticed clouds in two stones held up to the window. Step cuts do not forgive inclusions; they spotlight them. The owner had to re-flag the display and eat the difference on a parcel she could not resell.
Emerald cut is a margin driver for high-end boutiques, but it is also the cut most likely to fail at the sales counter if the clarity window is not inspected before it ships. Here is the spec that does it right.
The step-cut honesty problem
Emerald cut moissanite uses parallel step facets and a wide open table. Instead of scattering light, those facets act like a series of mirrors. That is the quiet, elegant look clients pay for — but it means any feather, cloud or crystal inside the stone is visible the moment you look through the table. A VS clarity grade on a round brilliant can look eye-clean; the same grade on an emerald cut can show a window.
Industry norm for wholesale emerald parcels is to accept stones at the GRA letter grade and ship them. Our QC goes one step further: every emerald stone is inspected face-up on a daylight rig before packing. The difference in rejection rate is real:
| QC step | Commodity supplier | Our bulk emerald spec |
|---|---|---|
| Inclusion check | GRA grade only | Eye-clean face-up under daylight |
| Cloud through table | Allowed if graded VS | Rejected |
| Color face-up | GRA color letter | Verified on daylight rig |
| Symmetry | Not re-checked | Checklist on every stone |
| Crack at corner | Allowed under girdle | Rejected (corner = setting stress point) |
What we enforce on every emerald parcel
Moissanite is a clean material by default, but step-cut parcels still need a human eye. Before an emerald bulk order ships, we run each stone through:
- Eye-clean window check: we hold every stone at 25 cm under a daylight-balanced lamp and reject any stone with a visible cloud, feather or crystal through the table. Our eye-clean pass rate on incoming emerald rough is about 88%; the other 12% is cut into smaller stones where the window is less obvious.
- Corner integrity: the four cropped corners of an emerald cut are the stress points during setting. We reject any stone with a nick or feather reaching a corner. Corner chips are the most common reason an emerald cut returns after setting.
- Color consistency: step cuts show body tone more than brilliants. We sort stones face-up so a parcel reads evenly on your tray, rather than mixing cooler and warmer stones that happen to share a GRA color letter.
- Polish on step facets: a rough polish line across a wide step facet is obvious. We return any stone with visible polish marks under 10x — a standard that matters more for emerald than for round.
Ordering guidance by buyer
High-end boutiques — emerald cut is your quiet-luxury play. Buy small parcels in 7x5 mm and 8x6 mm, in 14k gold or platinum settings. The client who asks for emerald cut is not comparison-shopping on price; she is comparison-shopping on the window. That is where our eye-clean pass protects your margin.
Custom designers — emerald cuts pair well with baguette side stones. We can supply matched emerald centers and baguette accents from the same cutting batch so the color and mirror pattern read as one stone.
Private-label lines — lock your clarity standard once. "Eye-clean face-up" is a human judgment; we hold that judgment across reorders so your catalog stays consistent. We can also supply IGI reports on request for lines that need stronger consumer-facing certification.

Frequently Asked Questions
What clarity grade should I buy for emerald cut moissanite?
Do not rely on the clarity letter alone. For emerald cut, require "eye-clean face-up" — inspected under daylight. Our bulk emerald parcels ship only after every stone passes that check, regardless of the GRA letter on the certificate.
Are emerald cut moissanite stones more fragile?
The four cropped corners are the weak points. We reject any stone with a feather reaching a corner before it ships, and your setter should use V-prongs or bezel protection on those corners. With that, emerald cut moissanite wears as well as any other shape.
What size emerald cut is most popular for wholesale?
The 7x5 mm and 8x6 mm sizes are the volume sellers. They fit standard solitaire heads, photograph well, and read as a serious center stone without crossing into investment-stone pricing.
Can you supply matched emerald and baguette sets?
Yes. We cut emerald centers and baguette accents from the same batch so the step-facet mirror pattern and color tone match across the ring. This is standard for bespoke three-stone designs.
What is the MOQ for emerald cut moissanite?
Our wholesale MOQ is 20 pieces per size. Because every stone is individually eye-clean inspected, sample parcels ship within 5 business days.
