 | "Mali Garnet crystals (sometimes called Grandite) on Vesuvianite. Extremely lustrous, dodecahedral, Grossular/Andradite Garnet crystals of large size comprise this specimen. The translucent, greenish-yellow crystals reach 3.1 x 3.1 cm. across. Very colorful. The name Mali was conferred on a previously unknown, brilliant, dispersive, yellow, green and brown garnet only a few years ago based on where the first specimens were being mined in West Africa. This region is still the only known source. Gemological study proved that the new gem's composition was intermediate between that of grossular (calcium aluminum silicate) and andradite (calcium iron silicate ). This composition led some to suggest it be called "Grandite", but the name never really caught on. The hybrid, Mali, seems to favor its grossular parent in terms of refractive index (1.77 in most specimens) hardness (7) and clarity, but derives its superb dispersion and luster from its andradite heritage."
