Physical properties
Hardness 6.5-7. Opaque, massive microcrystalline quartz with bright red color from iron inclusions. Vitreous to dull luster.
Formation & geological history
Forms in hydrothermal veins or sedimentary deposits where silica-rich waters percolate and deposit silica. The red color comes from hematite inclusions.
Uses & applications
Commonly used in lapidary for cabochons, carvings, and tumbled stones. Historically used for seals and amulets.
Geological facts
Jasper comes in many colors and patterns, but the solid red variety is one of the most recognized. The name means 'spotted or speckled stone'.
Field identification & locations
Identified by its rich, opaque red color, conchoidal fracture, and hardness greater than steel. Found globally, notably in India, Russia, and the USA.
