Zebra Jasper (usually a trade name for Serpentine or Basalt blend)

Physical Properties

Hardness: 3-6 (Mohs scale), Color: Mottled green and white/cream, Luster: Waxy to greasy, Crystal structure: Monoclinic (often massive), Specific Gravity: 2.5-2.6

Formation & Geological History

Formed through the hydrothermal transformation of ultramafic rocks (serpentinization) in the earth's mantle and crust, typically at low temperatures and high pressures.

Uses & Applications

Predominantly used for lapidary work, including ornamental spheres, carvings, beads, and home decor. Also popular in the metaphysical community.

Geological Facts

Despite the trade name 'Zebra Jasper,' this specific green and white variety is often actually a form of Serpentine or a mix of quartz and basalt. It is prized for its swirling, high-contrast patterns that resemble camouflage or animal prints.

Field Identification & Locations

Identify by its characteristic waxy feel and mottled green/white pattern. It is commonly found in metamorphic terranes such as those in South Africa, Brazil, or India. Unlike true jasper, it can often be scratched by a steel knife if it is more serpentine-rich.
