The 4mm Tennis Set Round Cut in black is the round cut reimagined. Up to 86.8 carats of hand-set black diamond simulants run across both chain and bracelet in a blacked-out finish that's deep, rich, and unlike anything else in the lineup. The higher combined carat weight makes this the most substantial Tennis Set we offer — bold in detail, dark in tone, and built for those who want something that hits on a different level.
