Description HESSONITE OCCURS in a very wide range of hues – colorless to black- but drives its name from the first specimen ever found, a distinctive gooseberry-green color. The orange-brown color of hessonite is due to manganese and iron inclusion. The best Hessonite (Gomed) is found in Sri Lanka in metamorphic rocks or gems gravel and sands. In Madagascar, Hessonite is often referred to as Cinnamon Stone. Other localities include Brazil, Canada and Siberia (Russia) as well Marine, California and New Hampshire in USA.
