We manufacture and wholesale HPHT and CVD lab-grown diamonds. Our combined monthly production capacity reaches 300,000 carats, supported by a large inventory of loose stones. We deliver consistent bulk supplies to jewelers worldwide.
Better Star invests in both HPHT and CVD manufacturing plants, delivering a stable monthly output of over 300,000 carats of premium loose lab created diamonds, establishing us as a key player in the global lab diamond wholesale market. Our fully integrated industrial chain cuts redundant costs, granting us prominent price advantages while all stones are produced under strict international 4C grading criteria.
We stock loose diamonds covering full carat weights, various fancy and round shapes, and comprehensive grades ranging from top D-F colorless VVS clarity to economical SI tiers. Each stone undergoes rigorous inspection of cut, polish, symmetry and fluorescence, with both untreated and color-enhanced options available, accompanied by official gem lab certificates.
Chemically and optically identical to mined diamonds, our lab cultured diamonds are widely used in engagement rings, wedding bands, fashion pendants and earrings. Amid the booming sustainable jewelry wholesale sector, our dual production lines ensure uninterrupted bulk supply. We provide flexible wholesale, OEM and ODM services for jewelers worldwide, offering steady inventory, competitive pricing and reliable long-term bulk sourcing solutions.
