Buyer pathways
Choose the right sourcing route
Dealers, jewelry factories, and private-label teams buy in different ways. Start with the route that matches your order model, then send a cleaner RFQ.
Dealer inventory
Loose and certified stones with weekly availability, certificate files, and price-tier conversation.
Jewelry production
Melee, calibrated lots, matched pairs, and repeatable parcels for pavé, bridal, and private-label runs.
OEM account setup
Target spec file, QC preferences, document checklist, shipment rhythm, and reorder history in one workflow.
RFQ entry points
Start from the way you actually buy
Wholesale buyers do not all need the same quote. Choose a path for loose selected stones, certified inventory, melee parcels, or bulk/OEM programs before sending the target list.

Buyer questions
Questions buyers usually ask before the first RFQ
Short answers on pricing variables, certification options, melee parcels, and export support help your team decide what to include in the target list.
Do you supply wholesale lab-grown diamonds for US and EU buyers?
Yes. We focus on B2B wholesale lab-grown diamond supply for jewelry brands, diamond dealers, importers, and production buyers in the US, Europe, and other import markets. Shipments can be prepared with packing lists, certificate files, and export documents.
Can you provide IGI certified lab-grown diamonds and GIA report options?
We can quote IGI certified inventory and coordinate GIA report options according to the buyer target list. Availability depends on shape, size, color, clarity, report type, and weekly market movement.
What affects lab-grown diamond wholesale price per carat?
Wholesale price per carat depends on shape, carat or millimeter range, color, clarity, certification, order volume, delivery timing, and whether the request is for selected stones or mixed parcels.
Do you handle lab-grown melee diamonds?
Yes. We can quote melee parcels with sieve sorting, color range control, and practical batch packing for pavé, halo, watch, and fashion jewelry production.
