FROM ROUGH TO RETAIL-READY QUALITY WORKFLOW
We keep CVD supply consistent by controlling key checkpoints across the full manufacturing workflow — from growth selection through to final certification.
Built for brands that require repeatable quality,
not variation between orders.
CERTIFICATION & TRANSPARENCY
CERTIFICATION & DISCLOSURE
For jewellery and retail use, diamonds are individually certified by internationally recognised gemmological laboratories.
- IGI certification supplied as standard
- GIA certification where applicable
- Lab-grown origin clearly disclosed on every certificate
Before certification, every stone passes through structured inspection stages aligned with our diamond quality control standards, ensuring grading consistency, finish accuracy, and compliance for global retail markets.
Certification documents clearly state carat weight, colour grade,
clarity grade, cut details, and growth origin — supporting
retail compliance and consumer confidence.
