Sugilite is a very rare natural mineral which comes predominantly from the Kalahari Manganese Field, Northern Cape, South Africa. The Kalahari Manganese Field is the largest sedimentary manganese deposit in the world and many rare and beautiful minerals come from the mines in this area.
There is very little sugilite left available in the world to mine and the finest material known as gel sugilite is even rarer. When pieces do become available they command eye-watering prices. A kilo of 'decent grade' rough sugilite currently costs in the region of £1200 ($1500) which is a wholesale price for someone like us who buys directly from one of the very few suppliers in South Africa.
This rough slab of sugilite has distinctive purple colour which sits on a matrix of bustamite and manganese. The back of the rock has an extensive covering of snow-white coloured crystals which sparkle incessantly as they catch the light but sadly they do appear to be a little flat in our photo.
