Each Signature has its own story, from Tanzanite mined forty kilometres from our door to the green fire of Tsavorite and the colours of our Gem Centre. Every piece is one of a kind, and every price is quoted privately.

Tanzanite Signature
Flagship · Found only in Tanzania

Tanzanite

One source on Earth, forty kilometres from our door.

Tanzanite is mined in one place on Earth: a few square kilometres of the Merelani Hills, just outside Arusha. Discovered in 1967 and named after Tanzania, it moves between deep blue, violet and purple as it turns in the light. Every piece here was chosen by our team in Arusha, close to the mines, and comes graded and certified.

Tsavorite Signature
New · East Africa's green garnet

Tsavorite

The other great gem of East Africa.

Tsavorite is a vivid green garnet, first found in the hills of north-east Tanzania in 1967 and named after Kenya's Tsavo National Park. Its green is clean and bright and holds in any light, and it is found in only a handful of places in the world. Long a secret of the trade, it is one of the most beautiful stones to come out of this land.
