Physical properties
Hardness of 6.5-7 on the Mohs scale, waxy luster, opaque, and exhibits conchoidal fracture.
Formation & geological history
Formed through the silification of sedimentary or volcanic rocks, rich in silica and iron impurities.
Uses & applications
Used primarily in lapidary work, ornamental carvings, and jewelry making.
Geological facts
Jasper has been utilized since ancient times for talismans, seals, and weaponry components due to its toughness.
Field identification & locations
