New and rare gemstones from East Africa
The gemstone region of East Africa is exotic and relatively new compared to the long established gemstone regions of South East Asia and Brazil. It extends from the island of Madagascar (Malagasy) in the Indian Ocean to mainland Mozambique then northward through Tanzania and Kenya.
Notable developments have been the discovery and marketing of Tanzanite, a new vivid blue variety of the mineral zoisite, and likewise the promotion of the emerald green variety of grossular garnet, called Tsavorite, from localities in Kenya and Tanzania. Both these new gemstones have limited production and so command high prices. These gems are the icing on the cake. Many more gemstones are available from this little frequented region.
