Physical properties

Formation & geological history

Formed in cavities in volcanic rock or ancient lava flows where silica-rich groundwater deposited layers of microcrystalline quartz over long periods. Most high-quality specimens originate from Namibia, Africa.

Uses & applications

Primarily used in jewelry, lapidary arts, and as ornamental or 'healing' crystals. It is popular for cabochons, beads, and carved points or wands.

Geological facts

Blue Lace Agate was originally discovered in Namibia by George Swanson in the 1960s. It is considered one of the rarest and most sought-after varieties of agate due to its delicate color banding.

Field identification & locations

Identify in the field by its distinct light blue and white wavy banding and its translucent nature. While often found in geodes, this specific piece has been cut and polished into a hexagonal point. It is commonly found in southwestern Africa and parts of Brazil.
