Physical properties
Hardness: 6.5-7, Color: Multi-colored (often yellow, red, brown, with grey/blue bands), Luster: Vitreous to waxy, Crystal Structure: Trigonal (microcrystalline), Cleavage: None, Specific Gravity: 2.58-2.91
Formation & geological history
Formed in cavities of volcanic rocks or as nodules in sedimentary rocks through the deposition of silica-rich fluids over time.
Uses & applications
Used in lapidary, jewelry making, and as a collector's stone.
Geological facts
Jasper and agate are both varieties of chalcedony. When they occur together, they combine the opaque, colorful patterns of jasper with the translucent banding of agate.
Field identification & locations
Identified by its waxy luster, hardness (scratches glass), and distinctive combination of opaque, colorful jasper and translucent grey/blue chalcedony/agate bands.
