Better Star wholesales yellow lab grown diamonds in a full range of clarities, carat weights and shapes. We also offer yellow lab created diamond jewelry alongside custom manufacturing for rings and bracelets.
Lab grown diamonds replicate natural diamond crystal structures via two mature growth technologies: HPHT and CVD. HPHT mimics underground geological conditions for fast crystal growth, excelling in vibrant fancy yellow tones; CVD forms diamonds layer-by-layer in gas chambers, ideal for larger stones with stable color saturation. Both boast identical hardness, brilliance and durability as mined gems, with diverse clarity grades, carat weights and cutting shapes available.


Better Star supplies loose HPHT & CVD yellow lab cultured diamonds at wholesale bulk prices. We deliver full custom jewelry services for yellow diamond rings and bracelets. Our yellow diamond jewelry features natural, long-lasting yellow hues integrated into crystal lattices without coating, ranging from pale lemon to vivid canary shades. Radiant warm fire brings unique luxury, supporting OEM/ODM personalized designs to match brand retail demands.
