Physical properties

Hardness: 6.5-7 Mohs; Color: Muted greens, purples, reds, and creams; Luster: Vitreous to waxy; Crystal Structure: Hexagonal (cryptocrystalline); Specific Gravity: 2.6-2.65.

Formation & geological history

Formed through the deposition of silica from groundwater into cavities in igneous or sedimentary rocks. The varied colors come from trace mineral inclusions like iron or manganese over millions of years.

Uses & applications

Primarily used for lapidary work including cabochons, tumbles, carvings, and ornamental jewelry pieces.

Geological facts

Fancy Jasper is often called the 'Stone of Tranquility.' Unlike typical jasper, it is known for its wide palette of earthy colors in a single specimen, often looking like an abstract painting.

Field identification & locations

Identify by its opaque quality, variable earth-tone colors, and smooth conchoidal fracture. Often found in India and Madagascar. It is a favorite for novice carvers due to its durability and aesthetic variety.
