About Our Black Diamonds

Our black diamonds are 100% natural, sourced primarily from Africa and acquired through our trusted network in Antwerp. Each stone is hand-selected for its rich, opaque color and smooth polish, offering high visual contrast and a sleek finish. Unlike white diamonds, black diamonds are prized for their surface luster and unique texture rather than internal clarity.
Black diamond, an unconventional alternative for April birthdays, brings a modern edge to the traditional diamond birthstone — symbolizing strength, individuality, and resilience.
