Inside the workshop
Nothing is subcontracted except stone growth and independent grading. A ring travels from a Rhino file to a finished, rhodium-plated piece without leaving the building, which is why we can quote a change on Monday and cast it on Wednesday.
Loose stones
2302 loose moissanite lots are catalogued by shape, size and colour — the same stones our setters pick from when a buyer asks for a matched pair.
Six checkpoints between enquiry and a tracked parcel. Each one has a named owner on our side.
Send SKUs or a drawing. We confirm stone, metal, plating, size run and a firm unit price within 24 hours.
For custom work a 3D file and photoreal render come back in 2–3 days, with two revision rounds included.
Print, tree, invest, cast. Silver and gold runs are separate to keep colour and hardness consistent.
Prong, bezel, pavé or channel. Stones are matched under a loupe before they touch metal.
Four polishing stages, then rhodium or 18K gold plating with thickness recorded per batch.
Stone security, plating thickness, sizing and hallmark are checked, photographed and packed.
GRA cards for moissanite, IGI reports for lab-grown, CTT heavy-metal and nickel-release test reports, and our Hong Kong Customs AML registration. Certificates are issued to the order, not to the website.

Attach SKUs, quantities and the finish you need. Quotes come back within one working day, with tier pricing at 10 and 50 pieces.
One piece for a sample order; 10 pieces unlocks the bulk tier and 50+ moves to production pricing. Mixed SKUs can be combined to reach the bulk tier.
Current factory listings for this category sit between $70–$260 per piece depending on stone size, metal and setting. Send the SKU list with quantities and we confirm a firm quote within 24 hours.
Yes. The same CAD file can be cast in 925 sterling silver, 10K, 14K or 18K white, yellow or rose gold. Gold weights and stone sizes are confirmed before casting.
Moissanite is supplied with a GRA card by default and IGI certification on request. Lab-grown diamonds ship with IGI or GIA reports when the order value justifies it.
Stock styles leave the workshop in 3–7 days. Custom CAD, casting, setting and plating run 12–18 days, plus 4–7 days for delivery by DHL or UPS.
