12.52ct Barrel Cut Cabochon bluish Green Tourmaline

Tourmaline is one of the most compositionally complex minerals on earth — a boron silicate whose astonishing color range is driven by trace elements that vary from deposit to deposit, crystal to crystal. This 12.52 cts Tourmaline of bluish Green strong hue from Brazil was selected for the Skyjems Archive not as an afterthought, but as a deliberate acquisition. It is entirely unheated and untreated — a distinction that places it in the top fraction of the global Tourmaline supply and is the single most important value driver in the collector market. Brazil's geological diversity — from Minas Gerais to the Amazon basin — has made it the world's most prolific producer of collector gemstones.
