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.
