Natural tortoiseshell is an exceptional material, long celebrated in fine eyewear for its translucency, warm amber tones, and remarkable durability.

​

Historically sourced from marine turtles of the Galápagos Islands, it is now strictly regulated under international conventions to ensure the protection of endangered species.

​

Today, only a very limited number of legally registered, historic stocks remain available, contributing to its rarity and exceptional value.

​

Lightweight, hypoallergenic, and highly resistant, tortoiseshell offers outstanding longevity when carefully maintained. Its transformation requires rare artisanal expertise, mastered by only a select number of highly skilled craftsmen.
