Boleite (classic material) (ex Irv Brown Collection)

Item Description

Here we have one of the most desirable old classics from Mexico! This rare potassium, silver, copper chloride is one of the great beautiful rarities, and highly sought after by collectors. This piece is a fine, sharp, lustrous, translucent, rich blue color cubic crystal of Boleite free of matrix. A small amount of what I believe is Malachite can be seen on the side of the crystal for a nice touch. The fact that the crystal is a full 1.0 cm makes it a very good size crystal for the specie. This piece is from the type locality and crystals of Boleite like this are almost impossible to find in today's market. From the worldwide thumbnail / miniature collection of Irv Brown.
