Very rare specimen of superb Boleite crystals up to 7mm on a matrix from the type locality Amelia Mine, Boleo District, Mexico. This is a classic Mexican rarity and usually the crystals are loose so matrix specimens are quite uncommon. It displays sharp cubic crystals with indigo-blue color to royal-blue areas. They are very well isolated and contrast strongly. They have truncated corners. It shows on both sides. In very good condition – some minor nicks. On acrylic base.

Fabulous!
