St Anne's Mine (St Anne Mine; St Anns Mine), Mwami, Karoi (Urungwe; Hurungwe) District, Mashonaland West, Zimbabwe

A sharp, striated, gemmy and lustrous, two-toned blue euclase crystal from the St. Anne Mine of Zimbabwe. The two blue colors are vivid. This is the classic locality that has produced by far and away the world's most intense blue crystals of the species. Specimens of this quality and color variety came out in the 1970s, with very little found as a trickle since (and those mostly of the same habit but a much paler, although attractive, pastel blue color with deep blue highlights only). Ex. Irv Brown Collection.
