Sugilite ring size 10 bowl 11 gram raw Libyan desertsize 10 sugilite ring in sterling silver. Sugilite is a rare cyclosilicate mineral found mostly in the Wessels mine in the Kalahari Manganese fields of South Africa. It exhibits a deep purple to pink colour with lots of black from the presence of Manganese and in some cases blue and red. It was first discovered in 1944 by Ken Ichi Sugi and was named after him. Sugilite has become increasingly difficult to source due to the one place that produces it.
