Physical properties
Hardness: 6.5-7 on Mohs scale. Color: Intensely bright blue (artificially dyed). Luster: Vitreous to waxy. Crystal structure: Cryptocrystalline. Cleavage: None.
Formation & geological history
Natural agate forms in cavities in igneous rock. This piece has been subjected to artificial dyeing to achieve its extreme blue color.
Uses & applications
Used in jewelry, decorative items, and crafts due to its hardness and ability to take dye well.
Geological facts
Agate is highly porous, making it relatively easy to dye artificially.
Field identification & locations
Identify by its banded or highly patterned appearance and its unnatural, intensely vibrant color, which is a key indicator of dyeing. Commonly found in Brazil, India, and the US.
