THE MATERIAL LIBRARY
Jasper
An opaque, fine-grained silica-rich ornamental material.
Colors & patterns
Earthy reds, browns, creams, greens and many landscape-like patterns.
Typical origins
Found in many countries, including the United States, India, Brazil and Australia.
Hardness
Usually about 6.5–7 for true jasper
Choosing & setting this material
Pattern placement makes each cab individual. Some materials marketed as jasper are other rocks, so verify identity before assuming quartz-level durability.
Care & cleaning
Clean gently with lukewarm water, a little mild soap and a soft cloth, then dry. Avoid steam, ultrasonic cleaners, harsh chemicals and sudden temperature changes, especially when treatments are unknown.
Origins above describe typical sources of the material, not the origin of an illustrated or stocked stone. Hardness measures scratch resistance, not resistance to breaking. Confirm the identity and treatments of the actual piece.
