Physical properties
Hardness: 6.5-7 (Mohs scale); Color: Microcrystalline blue with banded white layers; Luster: Waxy to vitreous; Crystal Structure: Hexagonal (Trigonal); Cleavage: None; Specific Gravity: 2.6-2.65
Formation & geological history
Formed through the deposition of silica from groundwater in the cavities of igneous rocks, specifically volcanic lava. This specimen shows a carved and polished finish from a larger nodule.
Uses & applications
Primarily used in jewelry, lapidary arts, ornamental carving, and as a metaphysical or collecting specimen.
Geological facts
Agate is a variety of chalcedony. Blue Lace Agate is particularly famous for its calming aesthetic and was first discovered in Namibia in the 1960s. This specimen is shaped into a decorative obelisk or point.
Field identification & locations
Identify by its characteristic blue and white wavy bands and its hardness (it can scratch glass). Commonly found in Namibia, South Africa, and parts of the United States. In the field, look for nodules with a waxy interior.
