A New York buyer opened a 50-stone parcel last month and found four stones with visible black carbon spots, two stones that did not match their GRA report numbers, and one stone with a chip hidden under the girdle. The supplier refunded, but the two weeks spent photographing and arguing cost the boutique a bridal show. Parcel grading is not a formality; it is the quality gate that decides whether your next 50 customer-facing stones are problem-free.
This guide walks through the inspection checklist wholesale buyers should run on every incoming loose-moissanite parcel, before the stones go into inventory and before they reach a setting bench.
The five-point parcel inspection
Run every parcel through these steps under a 10x loupe and a daylight-balanced lamp:
- Report match. Match every report number to the GRA or NGTC portal. Weight, measurements, color, and clarity should line up within rounding tolerance. A mismatched report is a red flag, not a typo.
- Measurement check. Gauge each stone. A 6.5 mm stone that measures 6.35 mm will not fit a 6.5 mm setting and will rattle. Reject stones outside +/- 0.07 mm of the labeled diameter.
- Eye-clean test. Hold the stone face-up at 20 cm under a lamp. If you see a dark spot with the naked eye, it is not eye-clean, regardless of what the clarity grade says. See our eye-clean standard for the exact bar.
- Girdle and culet check. Look for chips at the girdle edge and a rounded or nicked culet. Moissanite is harder than most gems (9.25 on the Mohs scale, per the moissanite reference) but still chips if the girdle is paper-thin.
- Fluorescence and tint. Hold the stone next to a master D-F white stone. A G-H grade should show only a faint warm tint through the pavilion; a clearly yellow body color is misgraded.
This checklist is the short version. We go deeper on the report-verification step in bulk parcel GRA verification and on the bench-side issue in girdle thickness when setting.
Parcel vs single-stone buying
A parcel is a mixed lot sold as a group, usually at a per-stone discount versus buying singles. The trade-off is that you do not hand-pick every stone. Wholesalers split parcels by grade tier: a "clean parcel" is pre-sorted to be eye-clean across the lot, while a "commercial parcel" has a small percentage of stones with minor inclusions that the bench can hide under prongs. For a bridal account, buy clean parcels for center stones and commercial parcels for melee and side stones.
Pricing is covered in carat weight price tiers, and the color mix decision in D-F vs G-H allocation.
What clean parcel means on the bench
When a supplier says a parcel is clean, they mean every stone in the lot passed their internal eye-clean check. It does not mean every stone is VVS. A clean parcel can carry VS2-SI1 stones that happen to be eye-clean at 20 cm. A commercial parcel might still be 90 percent clean, but the 10 percent that is not gets absorbed into melee or side-stone jobs where the flaw is hidden. For bridal center stones, always buy clean. For pav and melee, commercial is fine and saves you 10 to 15 percent per stone.
What to photograph before signing off
Before you accept a parcel, photograph every stone face-up, pavilion-up, and through the side, next to a ruler. Keep the photos for 90 days. If a stone later chips during setting, you have evidence it was chipped on arrival. Suppliers who do not want you to photograph the parcel are telling you something. The FTC Jewelry Guides also require accurate disclosure of any treatments, so a record of condition protects you on resale.
Reject ratios you should expect
A reputable supplier runs a 1-3% reject rate on incoming parcels. If you are rejecting more than 5% stone after stone, switch suppliers. If a supplier promises zero rejects, they are hiding rejects in the parcel and you will find them on the bench. Our reorder strategy piece includes a supplier scorecard you can use to track reject rates over time.
Should I buy parcels sight-unseen?
Only from a supplier you have bought from three or more times. First orders should always be photographed in advance. Many suppliers will send a video walkthrough of the parcel on request.
What is a normal parcel size?
Most wholesale parcels run 20, 50, or 100 stones. Smaller boutiques start at 20; assembly shops buy 50 to 100. HOLYCOME splits parcels across cuts and sizes on request.
Are parcel stones always certified?
Reputable parcels ship with one GRA certificate per stone. Parcels without certificates are cheaper but carry full grading risk on your side. We do not recommend them for bridal center stones.
How do I handle a stone that fails inspection?
Photograph it, send the photos and the report number, and ask for a replacement. A good supplier replaces within 7 days and covers return shipping. If they argue, that is your supplier-audit data point.
Order from HOLYCOME. Every parcel ships with per-stone GRA certificates, pre-inspection photos, and a 14-day reject window. We will split your parcel across the cuts and sizes you actually sell and replace any stone that fails your own inspection. Apply for a wholesale account and request the current parcel price list — minimum order 20 stones.
