Obsidian “Silver” from Armenia – Cabinet Specimen as a Unique Piece
This distinctive Obsidian specimen from Armenia displays a dark grey to almost black base colour with a striking silvery-grey sheen. Depending on the angle of the light, flowing, striped and curved structures become visible, giving the surface a lively, almost metallic appearance. The conchoidal fracture surfaces with their characteristic fracture lines and glassy lustre are typical of Obsidian. The specimen weighs approximately 664 g and is offered as the unique piece shown.
Geology & Locality
Obsidian is a natural volcanic glass formed when silica-rich lava cools very rapidly, leaving little time for crystals to develop. This “Silver” Obsidian is distinguished by its characteristic silvery sheen, which is particularly visible on the smooth fracture surfaces and changes with the angle of the light. Armenia has an extensive volcanic history and is well known for its various Obsidian occurrences.
