A retailer in Atlanta noticed princess cut moissanite had the best margin on his sheet and the worst return rate. Every returned stone came back with a chipped corner, and in every case the mounting had exposed the point instead of covering it. Princess is the most under-protected cut in the average tray: shoppers love the sharp square and the price, but a prong that sits beside the corner rather than over it turns a margin winner into a warranty claim. Buying the stones is half the problem; buying them with the right setting guidance is the other half.
Where princess margin leaks out
Princess cuts are high-yield from rough, so wholesale cost per carat sits below oval and cushion — which is why retail margin looks attractive. The leak is not the stone. It is the corner. A princess point is the most exposed sharp angle in any cut, and in a thin-prong solitaire it takes the full impact of every bump.
| Leak point | Cost to retailer | Fix |
|---|---|---|
| Chipped corner in setting | Stone replacement + labor + goodwill | Prong over the point, not beside it |
| Square vs rectangle mismatch | Customer returns "wrong shape" | Log ratio on the order |
| Pavé band overshadowing | Stone looks smaller than paid for | Pair with slim bands |
| Soft corner on incoming stone | Already-abraded point mounts badly | Reject on arrival |
The princess spec sheet
Princess moissanite ships at Mohs 9.25, DEF color, eye-clean clarity, GRA certified with a matching girdle inscription. Shape-specific standards:
- Square (1.00 to 1.05 ratio) and rectangle (1.10 to 1.30) logged separately, never mixed in one SKU.
- Corner condition checked under magnification before packing; any abrasion is rejected rather than discounted.
- Point depth and table size recorded so a reorder reproduces the same light pattern a client approved.
- Brightness verified under diffused light; princess should flash evenly, not show a dark center.
Because the stone itself is consistent, the real quality control happens at the setting bench. We supply a one-page mounting note with every princess parcel showing the four corner-protection positions, which most retailers tape to their bench. Princess also photographs well from the top, so a square listing image usually converts without the side-angle shots that oval and marquise require. Bench staff should still rotate the stone under a loupe to confirm no corner chip is hiding in the setting.
How retailers should buy and price princess
An opening buyer should stock square princess in the 1.00 to 1.50 carat band — it is the recognizable, easy-to-sell silhouette — and hold a small rectangle reserve for shoppers who want elongation. Pair every order with settings that cover the corners, and price the stone-plus-set as a package so the customer never buys a bare princess that later gets mounted wrong.
A high-end retailer can run the 2.00+ band for the statement solitaire, where princess undercuts oval pricing enough to widen margin. Our DDP export to the US and EU fixes landed cost at PO, and reorders on an approved square/rectangle ratio ship in five business days against the 20-piece MOQ.
Private-label programs should lock the corner-protection spec into their own mounting drawings, so every manufactured ring from the bench covers the point by default. Retailers who do this report princess return rates under 2 percent, against the 6 to 8 percent they see when corners are exposed.
Frequently Asked Questions
Why do princess cuts chip so often?
The four sharp corners are the thinnest, most exposed points. When a prong sits beside the corner instead of over it, the point takes direct impact. The stone's 9.25 hardness does not protect a sharp edge from a side blow.
Square or rectangle princess — which sells more?
Square is the recognizable best-seller and should be the anchor. Rectangle sells to shoppers who want elongation without moving to oval, so keep a smaller reserve.
Is princess cheaper than oval at wholesale?
Yes, typically. Princess is a high-yield square cut from rough, so per-carat cost runs below oval and cushion, which is why retail margin looks stronger when corners are protected.
What setting protects princess corners best?
Prongs that sit over the point rather than beside it, or a partial bezel. Thin prong solitaires that leave corners exposed are the source of most chipped-corner returns.
What MOQ opens princess wholesale pricing?
20 pieces in one carat band opens the rate. Square and rectangle should be split on the PO so the packing list matches your display SKUs.
What to take away
- Princess margin is real, but only when corners are protected at the bench.
- Separate square and rectangle SKUs; do not mix them.
- Reject incoming stones with already-abraded corners.
- Lock corner protection into private-label mounting drawings.
