Gorgeous Bulk Radiant Cut Lab Grown Diamonds & Rings
Rectangular trimmed-corner radiant blends step and brilliant facets for double vivid sparkle. Various fancy tones in stock, loose stones, finished jewelry and tailor-made services provided.
Radiant cut lab created diamonds adopt a unique rectangular frame with softly cropped four corners, combining the layered light texture of emerald cut and the blazing sparkle of princess cut, which differs greatly from rounded oval and tender heart shapes. Produced through mature HPHT and CVD techniques, they are available in white, warm yellow, delicate pink and cool blue fancy colors to meet diverse styling demands.
Dense mixed facets capture light from every angle to create explosive luster, and chamfered corners avoid easy chipping while bringing smooth, irritation-free wearing experience for all-day use. Its balanced rectangular outline fits stylish engagement rings, rectangular drop earrings and statement pendants perfectly.
We supply full-range loose radiant lab diamonds, complete matching jewelry sets and one-stop bespoke customization. Highly favored by customers pursuing both geometric sense and outstanding fire, these gems are top materials for bridal proposals, anniversary ornaments and personalized high-end fine jewelry.
