Physical properties

Formation & geological history

Formed in volcanic cavities where silica-rich groundwater deposited layers of chalcedony over long periods of time. Most high-quality specimens originate from the Karas Region of Namibia, dated back to the Precambrian or younger volcanic events.

Uses & applications

Primarily used as a gemstone in jewelry (cabochons, beads), decorative carvings, and in metaphysical practices for its calming aesthetic.

Geological facts

Blue Lace Agate was first discovered in the early 1960s by George Swanson in South-West Africa (now Namibia). It is a variety of chalcedony characterized by its delicate, wavy bands that resemble lace.

Field identification & locations

Identified by its distinctive light blue color and white scalloped banding. To differentiate from blue chalcedony or dyed agate, look for the natural, irregular wavy patterns. It is found almost exclusively in Namibia, though some deposits exist in South Africa.
