Leifite with Nenadkevichite (rare) (ex Francesco Bedogne Collection)

Item Description

A wonderful rarity from the famous locality at Mont Saint-Hilaire featuring radial "sprays" of Leifite with a small spot featuring blocky, golden-brown colored, gemmy crystals of Nenadkevichite. Now the Nenadkevichite crystals are micros, but they are beautiful to view under the microscope. We have photographed the piece with a Canon MP-E 65 mm macro lens to better illustrate the quality. Considering that Nenadkevichite has only been found in just over a dozen localities in the world, this is a great opportunity for a rarities collector to pick up a specimen of this hydrated sodium niobium cyclosilicate. From the worldwide collection of famed Italian mineral collector, field collector and author, Francesco Bedogne of Sondrio, Italy (Collection #1725). Bedogne wrote dozens of articles and several books about the mineralogy of Italian Alpine localities such as Val Bregaglia, Val Masino, Val Codera, Val Spluga, Valtellina and the famous Val Malenco. He was also the founder of the Valtellinese Mineralogical Institute.
