RARE A+ Natural Gobi Desert Agate (Southeast Asia) With Eyes 12x14-13x20mm, 4 Beads
Gobi Desert agate is a rare form of botryoidal chalcedony, not a typical agate, found primarily in the stream beds of Southeast Asia's Gobi Desert, spanning across northern China and southern Mongolia. Renowned for their grape-like or bubbly texture rather than just vibrant colors, these stones showcase a range of hues due to mineral impurities. Characterized by their globular formations, Gobi Agates have formed over an estimated 450 to 500 million years through the unique environmental conditions of the desert, where silica-rich solutions crystallized in cavities of host rocks, later to be exposed by erosion. While they do exhibit smooth surfaces, this is more a result of geological processes than wind or sand polishing alone.
