Certified 5, 6 & 7 Carat DEF Lab Grown HPHT Loose Diamonds — Reliable B2B Supply for Jewelry Manufacturers Worldwide

We are pleased to announce the launch of our dedicated B2B supply program for 5 carat, 6 carat, and 7 carat DEF lab grown HPHT loose diamonds. Designed specifically for jewelry manufacturers, wholesalers, and retail chains, this program ensures reliable, consistent access to premium large carat stones with full IGI/GIA certification and competitive trade pricing.

Built for B2B: What Sets Our Supply Program Apart

Consistency is the backbone of any successful jewelry manufacturing operation. Our B2B supply program addresses the key challenges that manufacturers face when sourcing large carat lab grown diamonds:

• Predictable Inventory: Maintained stock levels across 5ct, 6ct, and 7ct DEF color grades — no more last-minute sourcing scrambles.
• Consistent Quality: Every stone meets strict grading standards for color (D–F), clarity, and cut quality before entering our inventory.
• Flexible Order Quantities: From single stones for bespoke commissions to bulk orders for production runs — we accommodate your workflow.
• Fast Turnaround: Orders are processed within 24–48 hours with worldwide insured express shipping.

Certification & Quality Standards

Quality assurance is non-negotiable in B2B diamond supply. Every stone in our collection includes:

1. Independent Grading Report: Full certification from IGI (International Gemological Institute) or GIA (Gemological Institute of America) — the two most respected diamond grading authorities worldwide.
2. 4Cs Documentation: Complete documentation of carat weight, color grade, clarity grade, and cut quality for every individual stone.
3. High-Resolution Imaging: Professional 360° video and macro photography available upon request for remote assessment.
4. Laser Inscription Option: Optional laser inscription of certificate numbers on girdle for traceability and consumer confidence.
