About
A Zhejiang supplier focused on practical B2B diamond sourcing
Origin Lab Diamonds helps overseas buyers translate specification lists into repeatable loose lab-grown diamonds, IGI certified stones, HPHT, CVD, melee, and bulk lab-grown diamond supply.
Positioning
Factory-side execution with buyer-side communication
The business is positioned for buyers who value current availability, disciplined documentation, and a clear quote process more than generic brand storytelling.
Who we serve
Jewelry brands, diamond dealers, importers, e-commerce sellers, and production buyers in US and EU markets.
What we supply
Loose lab-grown diamonds, IGI certified stones, GIA report options, HPHT, CVD, melee, and bulk parcels.
How we work
Start with target list, quote current availability, prepare QC evidence, then pack for export.
Where we fit
Best for buyers who need recurring wholesale supply, not one-time consumer retail orders.

- English communication for international buying teams.
- Specification-focused quote workflow.
- QC evidence before shipment.
- Organized file handoff for repeat purchasing.
