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.
