Item Description

A huge 215-gram specimen of lamellar, intergrown krohnkite crystals from the famous deposits at Chuqui! This is a beautiful piece with elegant vertical form and the classic intense neon color, among the best neon blue of any copper-bearing species. They DO look fake, they really do, but they are totally natural and highly sought after rarities from the heyday of this mine in the earlier to mid 1900s. Few large speicmens are around today on the market. Just for the color alone, they go for good money (aside from the value as a mineralogical rare species). This specimen, as with most krohnkite, is composed of crystals grown together in a vein filling. It is terminated, such as they are, at both ends with microcrystalline growth tips that contacted the matrix which enclosed it. Valued $2000-2500
