A boutique in Denver that had sold only rounds for six months took a chance on emerald cut moissanite and lost the bet: the parcel arrived with several stones showing feather-like inclusions running across the open table. On a round, those inclusions would have been hidden by facet sparkle; on an emerald cut, they were the first thing the client saw. The store returned the lot and went back to rounds. The emerald cut is the highest-margin shape in moissanite wholesale, but it is also the shape where a careless supplier fails fastest. Below is the step-cut clarity standard we hold and why it matters to your margin.
Why step cuts are unforgiving
An emerald cut is a step cut: long, flat facets that look like hallways. That geometry produces a mirror-like “hall-of-mirrors” sparkle, but it also means there is nowhere to hide an inclusion. Three failure modes account for most emerald cut returns:
- Feather inclusions under the table. A feather that would be invisible in a brilliant reads as a white line across the open table of an emerald.
- Pavilion depth extremes. Too deep and the stone looks dark through the table; too shallow and it windows (you see through it).
- Off-square outline. An emerald that is slightly rectangular in outline reads as cheap once a client compares it side-by-side with a well-cut stone.
| Inspection point | Industry bulk norm | Our emerald parcel |
|---|---|---|
| Clarity under table | VS-ish, mixed | VVS eye-clean; no feather over 1mm visible through table |
| Pavilion depth | Not controlled | 38–43% range; no windowing, no dark center |
| Outline | Visual | Square or 1.3–1.5 L:W rectangle; off-outline flagged |
| Color | D–H mixed | D–F sorted; step cuts show warmth faster than rounds |
The emerald spec we publish
We grade emerald cut moissanite to the following tolerances, about 20% tighter than bulk suppliers:
- Clarity window: we require every emerald to be eye-clean from 30cm under north light, with no visible feather or crystal through the table facet. This is the single most important rejection criterion for step cuts.
- Proportions: pavilion depth held to 38–43%, crown angle 30–35. We reject stones that window or that show a dark, unlit center.
- Outline: we ship square emeralds (1.0–1.1 L:W) and rectangular emeralds (1.3–1.5 L:W) in separate trays. A mixed outline tray looks unfinished on a display.
- Finish: step-cut facets must be crisp and free of polish lines; we inspect each stone under 10x for facet-edge rounding.
- Certification: GRA on every emerald with clarity and outline noted. IGI documentation for US high-jewelery accounts on request.
Which emerald program fits you
Boutique adding step cuts for the first time
Start with a 20-stone parcel of square emeralds in the 1.0–1.5ct bracket, D–F. Square emeralds read as classic and modern simultaneously and are the easiest sell into a round-only clientele.
High-end bridal store
Carry both square and rectangular trays. Rectangular emeralds (1.4 L:W) are the red-carpet silhouette and anchor your display; they also pair beautifully with tapered baguette side stones, which we supply matched.
Private-label / OEM
We cut emeralds to your proportion and outline spec, carded under your brand. Minimum 50 stones per outline bracket. Export documentation covers EU and US DDP shipping with full customs paperwork.
Frequently Asked Questions
Do emerald cut moissanites sparkle less than rounds?
They sparkle differently. Rounds produce rainbow flashes; emeralds produce a quiet mirror-like flash. Clients who choose emeralds usually prefer the understated look, and they are less likely to compare their stone to a round in a store.
What clarity grade should I buy in emeralds?
Buy VVS eye-clean, specified on the PO. Emeralds at VS clarity show inclusions that would be invisible in a round, so a VS emerald is effectively a VS-on-a-step-cut and will return.
What MOQ applies to emerald parcels?
Opening MOQ is 20 emeralds in one outline and carat bracket. Reorders start at 10. Private-label programs require 50 stones per bracket.
Can I get matched baguette side stones?
Yes. We supply matched tapered and straight baguettes cut from the same batch, so the center emerald and side stones share color and clarity. Order them in the same PO for a color match.
How long do stock emeralds take?
Stock emeralds ship in 5 business days. Custom-outline or private-label parcels run 15–20 business days, DDP to US and EU addresses.
Why step-cut parcels carry a lower return rate
Counterintuitively, emerald cut parcels return at a lower rate than round parcels in our book, once the clarity bar is met. A client who chooses an emerald is buying the mirror-like step-cut look specifically and rarely walks in wanting a round. That lower substitution rate means a well-sourced emerald parcel sits in your case and sells to the client it was cut for, rather than sitting until someone price-shops a round.
Takeaways
- Specify VVS eye-clean through the table — step cuts do not hide inclusions.
- Reject any emerald that windows or shows a dark center.
- Keep square and rectangular outlines in separate trays.
- Order center and baguette sides from the same batch.
