The Devilline crystals appear as small but clearly visible, intensely colored aggregates on the surface. They show the typical strong blue to turquoise coloration and stand out clearly from the surrounding rock. Despite their small size, the crystals are well defined and give the specimen a very lively and collectible appearance. The crystalline character is clearly visible and creates an appealing level of detail for a micromount specimen.
Geology & Origin
Devilline is a rare hydrated copper sulfate that forms secondarily in the oxidation zones of copper deposits. It develops through the weathering of primary copper minerals under oxidizing conditions.
The New Cornelia Mine in Arizona is a well known copper deposit and produces a wide variety of secondary minerals, including rare species such as Devilline.
