Milarite – Val Giuv, Grisons, Switzerland
Ex Collection Émile Deyrolle (1838-1917)
 
Historical alpine rarity in the best quality and aesthetics!
This extremely rare beryl variety is named after the Val Mila in the Swiss canton of Grisons and is considered one of the rarest collector's minerals in the Alps. The Val Mila is right next to the Val Giuv. Since there are almost exclusively finds of milarit in the Val Giuv  it is assumed that the Val Mila was initially  wrongly named as a place of discovery to avoid a run of mineral collectors to the side. 
Only rarely do they reach a size that is clearly visible to the eye. Several milarites can be seen on this specimen, with the largest having a outstanding length of 1.1 cm. All crystals have a particularly good transparency and a great luster. Chlorite inclusions can be seen inside the crystals. The terminations are all crystallized and undamaged. A negative impression of a crystal can be seen on the largest Milarite.
Wonderfully aesthetic specimen of this extremely rare alpine classic.
