54.18 ct Pair Emerald Cut 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 matched pair — 54.18 cts Ametrine of Yellow / Purple hue — represents the rarest of gemological acquisitions: two stones of identical character, cut in harmony, from Bolivia. 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.
