Better Star operates two professional production factories for lab grown rough diamonds, covering both mature HPHT and advanced CVD synthesis technologies to satisfy diversified raw material demands. Our rough stones are categorized clearly based on crystal growth methods, then graded systematically by crystal shape, color, clarity and internal inclusion conditions before delivery.
Supported by complete industrial production lines, we maintain strong mass delivery capacity, stable uniform batch quality and competitive cost advantages.
These high-quality lab diamond roughs are widely supplied to global diamond cutting and polishing manufacturers, serving as core raw materials for producing finished melee, single-stone gems used in bridal rings, earrings, necklaces and luxury fine jewelry.

Better Star is a vertically integrated diamond and jewelry manufacturer based in Shuibei, Shenzhen — China’s premier jewelry manufacturing district. We grow the diamonds in our own CVD and HPHT laboratories, cut and certify them in-house, cast and set the jewelry in our own factory, and ship directly to your door in your branded packaging.
When you order from us, you pay factory cost — not distributor cost, not trading company cost. Every dollar that would have gone to intermediaries stays in your margin or product quality. We serve brands in 30+ countries, from boutique jewelers to major retail chains.
