THE BEAUTY OF THE AFRICAN GEMSTONE: GREEN TOURMALINE 🟩
❗ Over the past months, we have delved into the kaleidoscopic gemstone that is tourmaline and divulged its most interesting varieties.
🟢 This month, we are looking at Green Tourmaline.
🟢 For centuries, green tourmalines were sold as "Brazilian emeralds". The mistake was realised in the early 1700s when European mineralogists discovered that these gems attracted ash when heated (pyroelectricity); a property true emeralds lacked. True Brazilian emeralds were only discovered in Brumado in 1912.
🟢 To avoid deceptive trade names, European merchants coined "verdelite" from the Latin viridis meaning green. Today, the term is less common.
🟢 African sources of green gem tourmaline are abundant, including: Ethiopia, DRC, Kenya, Madagascar, Malawi, Mozambique, Namibia, Nigeria, Rwanda, South Africa, Tanzania, Zambia and Zimbabwe. Minor deposits are also present across North and West Africa.
