Nestled along the contorted shoreline at the southern tip of Lake Kivu lies the small town of Bakavu. Some of Congo’s finest Tourmaline is mined here by hardy artisanal miners who sink shafts along the rich Tourmaline reef nearby. Bakavu is a bustling Tourmaline trading town along with its neighbour Numbi. This stunning Tourmaline hails from this unassuming place. It was hewn from the Precambrian rock by a cooperative group of miners, but it formed many millions of years ago. Congo’s Tourmaline is formed from granitic pegmatites forming part of a Central African cluster of pegmatite fields. Pegmatites are “veins” of minerals within their host rock caused by mineral rich ground water and hot magma.

Caring for Tourmalines
It has a hardness of 7-7.5 on the Mohs Scale (similar to Emerald), Gems with a hardness of 6-7 or greater are quite suitable for rings which are worn occasionally. For a ring like a wedding or engagement ring, intended for everyday wear over a period of years, a hardness rating of 8-10 is recommended. Warm, soapy water is the best method for cleaning tourmaline. The use of ultrasonic and steam cleaners is not recommended.
