Clinochlore var. Ripidolite (rare) Henderson Coll.

Item Description

Ripidolite is a rare variety of clinochlore, a chlorite group species. This exceptional thumbnail is from the famous Val Malenco in Italy, a locality well-known for the species, but very seldom on the market in this quality. 8 mm, pseudo-hexagonal laminae of luminous, metallic-green ripidolite are beautifully inscribed with a nearly perfect equilaterial triangle. Classic material for the locale. A note on the label mentions Francesco Bedogne, co-author of a 1972 MIneralogical Record article (Vol. 3, No. 3) on mineral collecting in Val Malenco. Possibly collected by him. Ex Will Henderson Collection.
