Tanzanite Unheated Crystals
These rough, unheated, tanzanite crystals were an exciting find.
Tanzanite, which is a variety of the mineral zoisite, can only be found in Tanzania.
Said to be rarer than diamonds, it's renowned for its blue-to-violet colour, but most tanzanite is heated.
Heating enhances the shade and depth of colour and removes unwanted wisps of brown, yellow and black.
All tanzanite is considered to be heated unless stated otherwise.
These tanzanite stones have been cleaned and filed to smooth rough edges but are otherwise untouched.
They were purchased directly from a UK-based Tanzanian supplier.
I only have eleven stones available. Details are in the individual listings below.
Our first photo features all eleven pieces.
