IGI CVD Lab Grown Diamonds

IGI-certified CVD lab grown diamonds in 8ct to 20ct sizes offer a practical way to source large certified stones for wholesale, custom jewelry production, and inventory planning. Compared to many spot-market purchases, these diamonds provide clearer grading documentation, better traceability, and more predictable availability for engagement rings, diamond necklaces, tennis necklaces, and statement diamond jewelry.

• Available in 8ct to 20ct sizes for high-carat jewelry projects
• IGI certification supports clear, citable grading and buyer confidence
• CVD lab grown diamonds suit modern bridal and fine jewelry manufacturing
• Direct-from-factory sourcing helps support steady wholesale supply
• Quality control extends across lab grown and fancy color stone production
• Useful for custom orders, showroom stock, and global trade procurement

These diamonds are a reliable fit for retailers, wholesalers, designers, and private-label brands that need large stones for bridal collections, bespoke commissions, or exhibition-ready inventory. Unlike natural diamonds, which can be harder to source consistently at higher carat weights, lab grown CVD diamonds can make repeat orders, matched pairs, and coordinated sets easier to plan.

If you need certified large diamonds for custom rings, necklaces, or wholesale programs, this collection is built to streamline procurement while keeping certification and material details easy to verify. Explore the catalog to find the right fit for your next jewelry project.
