1.88ct Scissor Cut/Octagonal 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 1.88 cts Tourmaline of yellow-green vivid 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.
