ARMENITE from Switzerland * RARE MINERAL in GOOD TN SPECIMEN * 2,7 cm

Description

Armenite
Isenwegg, Wasen Alp, Brig, Wallis, Switzerland
Armenite is a rare Ba-Ca-Al silicate mineral of osumilite group. It forms well formed, colourless/white crystals with good luster associated with some quartz on gneiss matrix. It comes from a cleft I opened in 2015 and worked for 2 summer seasons, and produced unusually large specimens richly covered with gemmy armenite crystals. Wasen Alp is the world best locality of well crystalized armenite. Very nice and rich specimen.

size  2.7cm x 1.5cm x 1.2cm
