43.02 ct Square Ametrine, 100% Natural Very Rare Single Source Gem from Bolivia

Ametrine is a geological curiosity that exists in only one significant deposit in the world: the Anahi mine in Bolivia. This 43.02 cts Ametrine of Yellow / Purple hue from Bolivia 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 Ametrine supply and is the single most important value driver in the collector market. Bolivia's Anahi mine is the world's only significant source of ametrine — a geographical monopoly that makes every fine specimen a uniquely traceable artifact.
