The 4mm Tennis Bracelet Round Cut in black gives a classic silhouette a darker, more distinctive edge. Up to 23.8 carats of hand-set black diamond simulants sit against a blacked-out finish, creating a deep, striking contrast that's subtle in profile but impossible to miss. Pair it with the matching 4mm black Tennis Chain for a full blacked-out set, or wear it solo and let the wrist make the statement.
