Physical properties

Hardness: 6.5-7 for Jasper, 5.5-6.5 for Hematite. Color: Brick red and metallic grey/black. Luster: Vitreous to dull (Jasper), Metallic (Hematite). Structure: Hexagonal/Trigonal.

Formation & geological history

Jasper is a microcrystalline variety of quartz formed by silica-rich fluids in volcanic or sedimentary environments. Hematite forms as a primary mineral in iron-rich sedimentary deposits or via hydrothermal activity.

Uses & applications

Used extensively in jewelry as tumbled stones and beads, lapidary carvings, and as decorative pocket stones. Hematite is also a primary ore of iron.

Geological facts

Red Jasper is colored by high concentrations of iron inclusions. Hematite is famous for having a blood-red streak when rubbed against a rough porcelain plate, despite its metallic exterior.

Field identification & locations

Identify Jasper by its opaque red color and quartz hardness. Identify Hematite by its high density/weight and metallic shine. Common in diverse global locations including Brazil, India, and the USA.
