Physical properties
Hardness: 6.5-7 (Mohs scale), Color: Sky blue to pale lavender with white banding, Luster: Vitreous to waxy, Crystal Structure: Hexagonal/Trigonal (microcrystalline), Cleavage: None, Specific Gravity: 2.58-2.64
Formation & geological history
Formed through the deposition of silica in gas cavities of volcanic rocks over millions of years, often during the Cenozoic era. The distinct banding occurs as different layers of minerals crystallize.
Uses & applications
Primarily used in jewelry making, ornamental carvings, lapidary arts, and as a popular specimen for crystal healing and mineral collectors.
Geological facts
This specimen has been cut and polished into a point (obelisk shape). It is widely regarded as a 'stone of communication' in various metaphysical practices and is famous for its intricate, lace-like patterns.
Field identification & locations
Identify in the field by its distinct light blue color and delicate white banding. It is and almost exclusively sourced from Namibia, South Africa, and parts of Brazil. Collectors look for high contrast and clear blue shades.
