Physical properties

Hardness: 6.5-7 (Mohs scale), Color: Sky blue with white or light gray banding, Luster: Vitreous to waxy, Crystal Structure: Trigonal (Microcrystalline/Cryptocrystalline), Cleavage: None, Specific Gravity: 2.60-2.65

Formation & geological history

Formed through the deposition of silica from groundwater in the cavities of igneous rocks such as basalt. The characteristic layers represent different pulses of mineral-rich fluids over thousands of years.

Uses & applications

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

Geological facts

First discovered in Namibia, this specific variety of chalcedony is renowned for its delicate, lace-like patterns. It is often associated with tranquility and calm in metaphysical circles.

Field identification & locations

Identify by its distinctive pale blue color and thin, wavy white banding. Commonly found in Namibia, South Africa, and parts of Brazil. In the field, look for nodules with a waxy exterior.
