Volcanic Glass with Andalusite Inclusions – Carabaya Province, Puno Department, Peru

From the late Glenn Vargas* collection - an opportunity to own a piece of rough from a legendary collection

Extremely rare volcanic glass containing visible inclusions of andalusite from the Carabaya Province in Peru’s Puno Department. The glass has frosted surface that makes the inclusions subtle in photos, though they are clearly visible in hand. This unusual occurrence—andalusite within volcanic glass—represents a fascinating intersection of igneous and metamorphic mineral.
