Two regions in Madagascar; Andilamena and Vatomandry are recent additions in the world ruby mining map. Here ruby occurs in a large number of igneous rocks. Apply a little bit heat treatment and wow! They are almost equal to their Burmese cousins in beauty and vitality. They are special from the aspects of gemological and mineralogical properties too. The deposit discovered in the Andilamena region is quite substantial and has been much into production of rubies in recent years. The rubies mined in the Vatomandry region do not require heat treatment. The rubies mined here are found in attractive crystal forms in shades of orange, red and pink
