Signature began with John’s search for ethically-sourced, rare and exotic gemstones and his desire to create one-of-a kind, singularly personal pieces of wearable art.

In bringing this exceptional collection to life one piece at a time, Signature has come to represent the culmination of four decades of passion for his craft and his ongoing commitment to excellence.

Each piece is hand sketched, created in 18k gold by master artisans and authenticated by John’s signature.

Recent designs have been inspired by a tanzanite of exceptional color, or a brilliant trillion aquamarine or even a fiery Boulder opal. Whether a pendant, earrings or ring, each Signature design is modern and represents a new level of luxury.
