Physical properties

Hardness: 6.5-7 (Mohs scale); Color: Light blue with white or light-colored bands; Luster: Vitreous to waxy; Crystal Structure: Trigonal (Microcrystalline); Cleavage: None; Specific Gravity: 2.6-2.65

Formation & geological history

Formed in volcanic rock cavities (vesicles) through the deposition of silica from groundwater. The distinct banding occurs as different layers of minerals crystallize over time. Most famous deposits are approximately 50 million years old.

Uses & applications

Primarily used for lapidary arts, jewelry (cabochons, beads), and as a collector specimen. It is highly valued in metaphysical circles for its perceived calming properties.

Geological facts

The most famous and productive source of Blue Lace Agate was discovered in the Karas Region of Namibia, Africa, by George Swanson in the 1960s.

Field identification & locations

Identify by its distinctive light blue hue and delicate, wavy white or darker blue bands. Can be found in Namibia, South Africa, and parts of the US and Brazil. Check for a waxy luster and hardness to distinguish from dyed chalcedony.
