Signature Studs ⬩ Black Onyx

A longtime customer favorite, the Signature Studs have been part of KAUREUM since the beginning.

The original stone in the collection, Black Onyx remains one of our most enduring designs—a study in simplicity, contrast, and quiet confidence.

Treasured for centuries across cultures, Black Onyx has long been associated with strength, protection, and focus. Its deep, uninterrupted black surface offers a sense of grounding and stability, making it a stone often chosen during periods of growth, transition, and personal transformation.

Bold yet understated, Black Onyx pairs effortlessly with every wardrobe and occasion. Its timeless monochromatic palette has made it a staple in jewelry collections for generations, equally at home in formal settings and everyday wear.

Refined and versatile, these studs embody the philosophy at the heart of KAUREUM: creating modern heirlooms designed to be worn often and kept forever.

A KAUREUM classic.
