Domestically, this mint-green grossular garnet is called "menthol garnet" and abroad as "Merelani mint", and is only produced in Tanzania, and grossular garnet from other regions will hardly have such a color.
Like Rubilla and Paraiba in tourmaline, menthol garnet was singled out as a commercial variety because of its characteristic color, but in gemology, menthol garnet is essentially a vanadium-containing grossular garnet.
