Jasper containing epidote (Unakite-like)

Physical Properties

Hardness: 6-7 (Mohs scale); Color: Mottle red, brick-red, and pistachio green; Luster: Dull to vitreous; Crystal Structure: Microcrystalline (Trigonal/Monoclinic); Cleavage: None/Conchoidal fracture; Specific Gravity: 2.5-2.9

Formation & Geological History

Formed via hydrothermal metamorphism where basaltic or granitic rocks are altered by hot, mineral-rich fluids, replacing original minerals with epidote and quartz/jasper. Often found in mountain belts or riverbeds washing down from metamorphic zones.

Uses & Applications

Commonly used for lapidary work, cabochons, jewelry, decorative carvings, and as smooth river stones for meditation or home decor.

Geological Facts

This specific combination of red jasper and green epidote is often called Unakite if found in a granitic matrix. It is considered a stone of balance and vision in metaphysical circles.

Field Identification & Locations

Identify in the field by its distinct 'Christmas' color palette (red and green), its high hardness (it will scratch glass), and its lack of visible large crystals. Commonly found in the Blue Ridge Mountains of the USA and in pebble form on beaches and in riverbeds.
