Physical properties

Hardness: 6.5-7 Mohs; Color: Pale blue with white or darker blue banding; Luster: Vitreous to waxy; Crystal structure: Trigonal/Microcrystalline; Cleavage: None; Specific Gravity: 2.60 to 2.64

Formation & geological history

Formed in volcanic cavities where silica-rich groundwater deposits layers over time. Known deposits are primarily found in Namibia and South Africa, originating from the Precambrian period (roughly 500 million years old).

Uses & applications

Primarily used in jewelry (cabochons, beads), decorative carvings, and as a popular specimen for crystal healing and mineral collectors.

Geological facts

Blue Lace Agate was originally discovered in the early 1960s by George Swanson in Namibia. It is considered one of the rarest varieties of agate due to the specific conditions required to create its delicate blue lace-like patterns.

Field identification & locations

Identified in the field by its distinct light blue color and 'lace' or wavy banding. It is often found in areas with historic volcanic activity. Authentic pieces are translucent to opaque.
