About 4 Carat Cushion Cut Lab Grown Diamonds
4 Carat Cushion Cut Lab Grown Diamonds – Grand Presence with Timeless Romance
A 4 carat cushion cut lab grown diamond delivers remarkable size combined with soft, romantic elegance. Known for its gently rounded corners and pillow-like silhouette, the cushion cut offers a luxurious balance of vintage charm and modern brilliance. For UK buyers seeking a high-impact diamond that remains graceful and refined, a 4 carat cushion cut diamond is an exceptional choice.
Created using advanced CVD and HPHT technology, lab grown diamonds share the same chemical composition, hardness and optical performance as mined diamonds.
