Physical properties
Hardness: 6.5-7 (Mohs scale), Color: light blue with white or darker blue banding, Luster: vitreous to waxy, Crystal Structure: Trigonal/Microcrystalline, Specific Gravity: 2.58-2.64
Formation & geological history
Formed in cavities within volcanic rocks where silica-rich groundwater deposits layers of microcrystalline quartz over thousands of years.
Uses & applications
Primarily used for lapidary purposes, jewelry, ornamental carvings, and as a popular collector's stone for its calming aesthetic.
Geological facts
The most famous and high-quality blue lace agate comes from the Karasburg district in Namibia, discovered in the early 1960s.
Field identification & locations
Identify by the distinctive delicate, wavy blue and white banding. Found in arid regions with historical volcanic activity. Collectors look for high contrast and consistency in banding.
