Physical properties

Hardness of 6.5 to 7 on the Mohs scale, red and black patterned coloration, vitreous to dull luster, cryptocrystalline structure, conchoidal fracture, specific gravity of 2.58 to 2.91.

Formation & geological history

Formed through the deposition of silica-rich solutions in sedimentary environments or hydrothermal conditions, often occurring in ancient marine or volcanic settings, with ages varying widely from Precambrian to Cenozoic.

Uses & applications

Commonly used for tumbled stones, cabochons in jewelry, ornamental carvings, and collector specimens.

Geological facts

Poppy Jasper is named for its distinctive orbicular patterns that resemble poppy flowers, often formed by concentric rings of contrasting minerals within the chalcedony matrix.

Field identification & locations

Easily identified by its smooth tumbled texture, characteristic red and black orbicular or dendritic patterns, and high hardness which scratches glass. Frequently found in regions with historical volcanic or sedimentary activity such as California.
