Physical properties

Formation & geological history

Formed through the infiltration of silica-rich fluids into volcanic ash or fine sediment, followed by the oxidation of iron and other minerals which create the 'flame-like' colored patterns. This specific variety is primarily found in Madagascar.

Uses & applications

Used extensively in the lapidary arts for spheres, cabochons, and decorative carvings. It is popular in the metaphysical community for jewelry and meditation aids.

Geological facts

Also known as Desert Jasper, it was discovered relatively recently in 2006 near the coast of Madagascar. Each piece is unique due to the random nature of the mineral impurities seeped into the quartz.

Field identification & locations

Identify by its opaque nature, high polish, and distinct rhythmic swirls or 'flame' patterns of color that blend smoothly into one another. It lacks the geometric lines seen in agate.
