6.3 x 4.5 x 2.8 cm. Aheylite is all of the nearly solid covering of greenish-colored botryoidal crystal aggregates on black cassiterite, here. The small acicular crystals are a rare habit of wavellite, surprisingly (sometimes mistaken for single aheylite crystals). X-Ray confirmed. Ex. Richard Kosnar Collection.

Aheylite on Cassiterite from Haununi Mine, Dalence Province, Oruro Dept., Bolivia (TYPE LOCALITY) [db_pics/pics/rare08-2-01c.jpg]

Aheylite is all of the nearly solid covering of greenish-colored botryoidal crystal aggregates on black cassiterite, here. The small acicular crystals are a rare habit of wavellite, surprisingly (sometimes mistaken for single aheylite crystals). Alan Heyl noticed this new species on cassiterite obtained from a small lot that Richard Kosnar had obtained from longtime sources in Bolivia, from which he has imported for some 30 years. The Kosnar family kept this specimen since, as the single richest example they had gotten, in their Bolivian collection. This remains the type and only locality for the species and I believe this to be, from the extent of my knowledge, most likely the richest specimen of the find (also making it a META-TYPE piece since it came from the same find as the type specimen, from the discoverer). XRAY confirmed. ex. Richard Kosnar Collection

Aheylite on Cassiterite from Huanuni Mine, Huanuni, Prov. Dalence, Dept. Oruro, Bolivia [db_pics/pics/t07-99a.jpg]

Pastel blue, translucent, spheres to .2 cm across of the very rare phosphate, aheylite, are perched on very lustrous crystals of cassiterite, to .6 cm across, along with colorless, quartz crystals. Aheylite, a hydrated, iron, aluminum, phosphate, is a member of the turquoise group. IT IS VERY RARE! This specimen is one of several obtained by Brian Kosnar in Bolivia many years ago, from which came the type material. These spheres are large for the species, and overall it is a pretty piece, too.
