The Celestial Moon Onyx Charm is a study in contrast—mysterious, radiant, and carved with intention. Crafted from black onyx, this disc-shaped charm features a hand-carved crescent sliver illuminated by hand-cut mother-of-pearl inlay. Surrounding it, engraved celestial rays reach outward toward a sparkling bezel-set CZ (Cubic Zirconia), creating a perfect balance of shadow and shine. Attached to our effortless C-clasp, it clips seamlessly onto any Starter Chain within the Charm Builder Collection.

Onyx is believed to offer strength, grounding, and protection—qualities that anchor the charm’s darker tones. The mother-of-pearl crescent brings light, intuition, and calm, echoing the moon’s gentle glow breaking through a night sky. Together, the pairing creates a piece that feels both powerful and serene.

Wear it solo for a bold focal moment, pair it with softer charms to play with contrast, or let it become the center of a full celestial cluster. The Celestial Moon Onyx Charm feels like a guiding night light—mystical, modern, and made to shine in its own quiet way.

A little shadow, a little glow, and a whole lot of celestial magic—ready to transform any charm story.
