3.19ct Emerald Cut Pink & Green Bi-Colour Tourmaline

Bi-colour tourmaline represents a geological phenomenon so rare it borders on the miraculous — a single crystal that shifted its chemical composition mid-growth, producing two distinct, harmonious hues within one stone. This 3.19 cts Bi-Colour Tourmaline of Pink & Green moderately 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 Bi-Colour 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.
