Fine thumbnail for the species and locality, a greenish crystal of chrysoberyl with little matrix. In good condition. The alpine town of Sondalo, located in the Sondrio province of Lombardy, Italy, sits within the rugged valleys of the central Alps, where historical land use has ranged from local agriculture and traditional alpine trades to significant civil engineering projects like the nearby medical sanatorium complexes of the twentieth century. Geologically, the area is situated in the Austroalpine basement units, characterized by complex metamorphic sequences, gneisses, and intrusive magmatic bodies affected by major tectonic structures such as the Periadriatic Seam. Within this complex metamorphic and pegmatitic framework, local mineral occurrences include accessory phases such as beryl and chrysoberyl, formed through high-temperature fluid interactions and regional orogenic processes.
