Colour

Tanzanite is graded on colour first: the richer and more even the violet-blue, the rarer the stone. We will show you real stones in the depth you choose.

About the stone

Tanzanite is found in one place on earth — the Merelani Hills, an hour from our door. Every stone we set is chosen by our gemologists for colour first. We grade clarity in three steps — Internally Flawless, Small inclusion and Medium inclusion — and tell you exactly which your stone is before we make anything. The price depends on the stone we find for you; we send options and you choose.
