One of a Kind

One-of-a-kind gemstone jewelry, shaped around a single stone.

Every piece on this page exists once. A stone is chosen for its individual color, clarity, and light. The setting is designed around it, forged and finished by hand, and never repeated. When a one-of-a-kind piece is acquired, it leaves the collection permanently.

Rings, necklaces, and earrings appear here from across kataoka's collections: tourmalines, aquamarines, sapphires, emeralds, Paraiba tourmalines, diamonds, moonstones, opals, and spinels in 18k beige gold and rose gold. Peter Ivy glass pieces complete the selection. Read the chronicle.

Still life with fruit under glass in the kataoka atelier, evoking the singularity of one-of-a-kind craft
