Zebra Jasper

Hardness: 6.5-7 on Mohs scale; Color: Striking black and white or brownish-white banding, sometimes with shades of pink or red; Luster: Dull to vitreous; Crystal structure: Microcrystalline, cryptocrystalline (fibrous aggregates of quartz); Cleavage: None; Specific gravity: 2.58-2.91

Zebra Jasper is a sedimentary rock that forms from the compaction and silicification of fine-grained sediments. The distinct banding is thought to be a result of rhythmic deposition of different layers of sand and clay, often with varying iron contents, over millions of years. It can be found in various geological ages depending on the specific deposit.

Primarily used in jewelry (beads, cabochons, carvings) due to its distinctive patterns. Also used for ornamental objects, interior decoration, and as a popular material for lapidary artists. It has a high collecting value for its aesthetic appeal.

Jasper is a cryptocrystalline variety of quartz, meaning its crystals are too small to be seen with the naked eye. The name 'jasper' is derived from the Greek 'iaspis', meaning 'spotted stone'. Zebra jasper is known for its bold, stripe-like patterns, which resemble a zebra's stripes. It is often believed to have grounding and motivational properties in metaphysical circles.

Zebra Jasper can be identified in the field by its characteristic black and white (or sometimes brown/pink and white) striped patterns. It feels relatively smooth and hard. It is commonly found in areas with sedimentary rock formations, notably in Australia (Kimberley region) and parts of Africa. For collectors, look for well-defined banding and vibrant contrast in colors.
