Green tourmaline Ring / new- 1.58 g - (1)

Ring with Green Tourmaline Bezel-set in 925 sterling silver New and unworn Green tourmalines are also referred to as verdelite. This designation, however, does not indicate any mineralogical assignment to a specific type of tourmaline. The name verdelite simply describes the color of the tourmaline. The mineral group of tourmalines comprises a series of boron-containing, similar ring silicates with a complex structure. Today twelve tourmaline varieties are distinguished, most of which occur as solid solutions. In the past, the name 'tourmaline' was a catch-all term for unknown, usually red gemstones and was in the 18th century in Europe derived from its Sinhala origin, meaning 'something small from the earth' (toramolli). Today tourmalines are often described as the 'gemstones of the rainbow' due to their many colors.
