Buyers purchase loose moissanite for three distinct purposes, and the specification differs for each: calibrated melee for halos, channels and pave; accent sizes for three-stone rings and earring settings; and large singles for solitaires and statement pendants. Selling them as one undifferentiated loose moissanite line is the most common planning error we see, because the sorting and tolerance requirements are completely different.
| Category | Size range | Sorting tolerance | Parcel documentation |
|---|---|---|---|
| Melee | 1.0 to 2.5 mm | 0.05 mm, or 0.03 mm on request | Size range, piece count, total carat, colour band, clarity band |
| Accent | 3.0 to 4.5 mm | 0.05 mm | Same, plus individual weight range |
| Centre | 5.0 to 8.0 mm | 0.1 mm | Same, plus count and average weight |
| Large singles | 9.0 mm and above | Individual, to specification | Individual weight and dimensions per stone |
The parcel sheet is the single most important document in a loose stone order. Without a stated actual size range you cannot plan a setting run, because a channel cut for 1.50 mm will not accept a parcel that runs 1.45 to 1.60 mm without rework. Always ask for the actual range rather than the nominal size.
| Shape | Common sizes | Notes |
|---|---|---|
| Round brilliant | 1.0 to 15 mm | The volume shape; cut quality affects brilliance most |
| Oval | 5x3 to 12x8 mm | Second most requested centre shape |
| Cushion | 4 to 10 mm | Popular in halo settings |
| Pear | 6x4 to 12x8 mm | Drop earrings and pendants |
| Marquise | 6x3 to 12x6 mm | Side stones and east-west settings |
| Emerald cut | 6x4 to 12x8 mm | Fewer facets, so cut precision is more visible |
| Princess, radiant, heart | Various | Order against specific demand rather than stocking |
