Cushion cut lab cultivated diamonds own a signature rounded square frame paired with blended brilliant and step facets, creating soft, velvety light performance unlike the sharp geometry of Asscher or slim teardrop silhouette of pear cuts. Manufactured by HPHT and CVD technologies, they come in white, vivid yellow, romantic pink and cool blue fancy colors to satisfy varied aesthetic preferences.
Smooth curved edges avoid snags and edge chipping, bringing cozy, weightless wearing comfort for all-day use. Their warm luminous glow makes them perfect for vintage engagement rings, cocktail pendants and elegant drop earrings.
Better Star provides full-sized loose cushion lab diamonds, ready-made matching jewelry sets and one-stop personalized customization. Ideal for clients pursuing romantic retro luxury, these gems serve as core materials for custom bridal gifts and high-end daily statement jewelry.
