Black Diamonds
Black Diamonds – Bold. Iconic. Distinctly Catherine.
Catherine Angiel was among the first to use black diamonds in fine jewelry, long before they became a trend. Her signature designs gained a cult following among artists, creatives, and celebrities drawn to their edge and individuality.
Handcrafted with intricate detail and inspired by tattoo art, each piece fuses strength, style, and unmistakable identity. These are the designs that made her name.
