Physical properties

Hardness: 6.5-7.0 (Mohs). Color: Light blue with white or darker blue banding. Luster: Vitreous to waxy. Crystal structure: Trigonal/Microcrystalline. Cleavage: None. Specific gravity: 2.58-2.64.

Formation & geological history

Formed through the deposition of silica-rich groundwater in the volcanic rock cavities (vesicles). Mostly associated with volcanic activity from the Precambrian to Cenozoic eras.

Uses & applications

Predominantly used for lapidary work, jewelry (cabochons and beads), and as a collector's stone or decorative healing crystal.

Geological facts

First discovered in Namibia in the 1960s. It is a rare variety of agate known specifically for its thin, delicate, lace-like blue and white banding which creates a cooling visual aesthetic.

Field identification & locations

Identify by its translucent blue layers and distinct white parallel banding. Commonly found in Namibia, South Africa, and parts of Brazil. Collectors should look for high-contrast banding and lack of fractures.
