In 1994 a new type of garnet was discovered in the African nation of Mali. A mix of two relatively rare and valuable gem garnet types–andradite and grossularite–this new garnet was named “Mali Garnet” in honor of the locality of discovery. The most well-known gem grossular is tsavorite, and the most well-known andradite gem is the rare demantoid. Mali garnet has a relatively high refractive index, giving it a beautiful brilliance which is enhanced by the high dispersion of demantoid, giving it a lovely “fire.” The color can range from brownish to a bright green, with rarity and value increasing as the color follows that trend. This Mali garnet is a beautiful almost pure yellow color (there’s just a tint of green) and it has lovely dispersion that can’t be captured in this photo–making it reminiscent of a yellow diamond. It weighs 0.67 carats and measures 4.95 x 3.63 mm. I faceted it in my own version of the classic diamond round brilliant cut which has been optimized for gems like this one to maximize the brilliance and dispersion.
