Polychrome jasper is a variety of jasper, which is a microcrystalline form of quartz made of silicon dioxide (SiO₂).
-
It is known for its wide range of colours, including reds, browns, creams, blues, greens, and greys, often appearing together in swirls, bands, or patchy patterns.
-
The colours are caused by different mineral impurities, such as iron and other trace elements, mixed into the quartz during formation.
-
Polychrome jasper is usually opaque and has a smooth, earthy appearance rather than a glassy transparency.
-
It has a hardness of about 6.5 to 7 on the Mohs scale, making it fairly durable for handling and polishing.
-
Each piece is visually unique, with no two stones showing the same colour patterns.
-
Polychrome jasper is sometimes sold under the name “desert jasper,” though this is a trade name rather than a scientific term.

The main source of polychrome jasper is Madagascar
