Signet Ring with Natural Onyx in 18K Gold

A natural onyx set in an 18K gold signet — a ring with the authority of a mark and the depth of a stone that absorbs everything.

The signet ring is among the oldest forms in jewelry — originally a seal, always a statement of identity. This version replaces the traditional engraving with a natural onyx stone, black and absolute, set flush within the 18K gold frame.

At 5.6 grams, the ring carries the weight its history demands. The natural onyx — mined, not manufactured — holds a depth that is architectural rather than decorative. It does not reflect. It absorbs.

For those who understand that authority is never performed, only carried. A ring that works on any hand that chooses it.

Ricca Jewelry. 18K gold. The mark of a decision.
