Spring 2020
Fine Swiss Adularia crystals up to 2.4 CM with green zoned inclusions of Chlorite are well presented on the matrix. From the type locality (St Gotthard) Most of these crystals have a slight dusting of Chlorite on the outside as well but the majority of the faces are glassy and transparent. Very pleasing esthtetics from almost any angle this is a choice and showy specimen of a usually unimpressive specie. No damage which is incredible for a piece with this complexity. Excellent Alpine classic that shows the textbook monoclinc form perfectly.
A super sharp, clear and lustrous gemmy Adularia crystal is nicely perched on matrix. A very old specimen, ex Roberto Palumbo (Rome, Italy mineral dealer active 1928-1945) with his label. The Feldspar is distinctly twinned as well and perfcely undamaged even at high magnifications. The locality of Monte Forno in the Piedmont has several well known alpine localities on it but also many tiny clefts that were worked mostly by Swiss Strahlers over a very long period. This is a choice piece with the Adularia well above the matrix and presenting well from all sides.
