Physical properties

Hardness: 6.5-7 on Mohs scale; Color: Pale blue with white or darker blue bands; Luster: Vitreous to waxy; Crystal Structure: Trigonal/Microcrystalline; Cleavage: None; Specific Gravity: 2.60-2.65

Formation & geological history

Formed through the deposition of silica from groundwater in cavities of igneous rocks (volcanic lava). This specimen exhibits the characteristic banding formed by rhythmic crystallization.

Uses & applications

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

Geological facts

Blue Lace Agate was originally discovered in Namibia. It is highly prized for its calming appearance and the delicate, lace-like patterns that form unique topographical designs in every stone.

Field identification & locations

Identify in the field by its distinct light blue and white color banding and its waxy luster when broken. It is most famously found in the Karas region of Namibia.
