CVD lab grown diamonds are produced via Chemical Vapor Deposition technology, forming pure Type IIA crystals layer by layer. Chemically, optically and physically identical to natural diamonds, they feature exceptional clarity and can grow into larger carat sizes, making them a sustainable, cost-effective alternative to mined stones.
As one of the world’s most vital CVD lab diamond manufacturers and global wholesale suppliers, Better Star delivers unmatched comprehensive product portfolios, premium consistent quality and factory-direct competitive pricing for jewelry distributors and brands worldwide. Our stable monthly production capacity hits 100,000 carats of polished CVD loose diamonds, covering all common shapes, color grades and clarities from small melee to large custom-sized stones.
Supported by our integrated cutting and polishing workshops, every diamond undergoes strict 4C grading inspection, with full IGI/GIA certification available. We implement full vertical industrial control from crystal growth to finished stones, eliminating intermediate markups and securing steady bulk inventory. We offer flexible OEM customization, transparent treatment disclosure for post-growth HPHT color correction, and reliable long-term supply solutions to partners across every continent.
