Physical properties
Hardness of 6.5 to 7 on the Mohs scale, red or brownish-yellow color with orbicular patterns, waxy luster, and trigonal crystal structure.
Formation & geological history
Forms from the silica-rich precipitation in volcanic ash or hydrothermal environments, often dating back to the Precambrian or later periods.
Uses & applications
Used primarily in lapidary arts, tumbled stones, ornamental carvings, and jewelry.
Geological facts
The distinctive orbicular patterns resemble poppy flowers, giving the stone its common name.
Field identification & locations
Identified by its characteristic reddish brown matrix featuring contrasting dark orbicular inclusions, commonly sourced in California.
