How to Buy Loose Moissanite by the Carat — Wholesale Guide for Jewelers

Short answer: Loose moissanite is simplest to buy when it's priced by weight: at Caratura it's a flat $26 per carat (from $13 for 0.5 ct), D color / VVS clarity, cut to standard millimeter sizes per shape — with the price listed openly, no quotes to chase. Order by carat weight, check the mm size against your setting, and expect the stone to arrive hand-inspected with a pre-ship video.

Step 1 · Decide by millimeters, not just carats

Carat weight sells the stone; millimeters set the stone. A 1 ct round runs ≈6.5 mm, a 1 ct oval ≈7×5 mm, a 1 ct pear ≈8×5 mm — same weight, different footprints. Always confirm the mm spec against your mounting before ordering. (Full size-by-shape charts are on each product page.)

Step 2 · Understand flat per-carat pricing

Some suppliers price each size individually and make you ask; transparent sellers publish one rate. Ours: $26/ct at every size — 0.5 ct = $13, 1 ct = $26, 3 ct = $78, 10 ct = $260. If a supplier says "contact for price" on a commodity stone like moissanite, that's friction you don't need.

Step 3 · Verify before it ships

For moissanite, a GRA card is effectively a receipt — not independent grading. What actually protects you: a stated size tolerance, hand inspection of your actual stone, and a pre-ship video so you approve what's really being sent. Ask for all three from any supplier.

Step 4 · Check the remedy and the landed cost

Confirm in writing: what happens if the stone arrives not as described (ours: report within 14 days — free replacement or refund), and whether duties are included (we ship DDP to nearly all destinations; where prepayment isn't possible, any charge on delivery is refunded in full). The listed price should be the price at your door.
