$25.00 CAD
1 Only
Allophane is a hydrated aluminum silicate that is unusual in that it does not form distinct crystals. Instead, it typically occurs as rounded, botryoidal or globular aggregates composed of extremely fine particles. Its appearance can range from waxy masses to attractive, slightly translucent formations.
The pale blue-green allophane patches contrast nicely against the rusty orange-brown limonitic matrix and the darker black manganese-rich areas. The specimen has a very natural, geological look. It tells a story of secondary mineralization.
Rare mint-green Allophane from the famous Kelly Mine is particularly interesting for its blue to blue-green colour. The mine is a historically important mineral locality in New Mexico, better known for its smithsonite but also producing a variety of less commonly encountered secondary minerals. Excellent thumbnail locality specimen for advanced mineral collectors.
