What Jasper is

Jasper is an opaque, fine-grained silica-rich material coloured and patterned by mineral impurities. Its listed Mohs hardness is 6.5–7, and its crystal system or structural category is Trigonal (quartz aggregate). The chemical composition is commonly written as SiO₂.

What to look for when buying

Names such as ocean, picture, brecciated or polychrome jasper can be useful trade descriptors but should not be treated as formal mineral species. Treatments are not automatically a problem, but they should be disclosed. For jasper, common treatment or enhancement notes include: Dyeing and stabilisation occur; many fantasy trade names refer to pattern rather than a distinct mineral species.

Care and display

Water: Generally durable for brief water contact. Light: Most varieties are stable in normal indoor light.

Traditional associations

In modern crystal traditions, jasper is often associated with grounding, endurance, stability. These are cultural or spiritual associations rather than scientifically demonstrated effects. A crystal should not be used as a substitute for medical, mental-health, financial or other professional advice.

Where it works visually

Common display ideas include desk, living room, entryway. Placement should also account for hardness, cleavage, sunlight, humidity, pets, children and how easy the specimen is to knock over.
