All of our Sugilite has either been sourced directly in South Africa, or has come out of old estate collections or lapidary hoards. Most of our Sugilite has been photographed both wet and dry. Sugilite is a popular pink and purple color shift mineral. Translucency is the first priority in grading Sugilite, with pure "gel" (without cracks) being the most valuable. Secondly, Sugilite grows with a variety of other minerals, some of which add value, and some of which take away. Manganese is almost always present with Sugilite rough. The more black manganese that is present, the less valuable the stone. The main deposit of commercial quantity of Sugilite has always been a few of the larger Manganese mines in the Kalahari, South Africa, Wessels, and N'chwaning. Being larger scale manganese ore mines, Sugilite is a byproduct, and often not the focal point of these operations. If you have any old stock, we are always interested, and we buy regularly if price and quality match our needs.
