Uses & applications

Widely used in lapidary arts, tumbled stones, cabochons for jewelry, carvings, and as a collectible specimen for rock enthusiasts.

Geological facts

Poppy jasper is famous for its distinctive orbicular patterns that resemble the petals of poppy flowers, often containing inclusions of hematite, goethite, or clay minerals that give it the characteristic warm red and brown tones.

Field identification & locations

Identified by its opaque nature, waxy luster when polished, and distinct orbicular 'poppy-like' dots or patterns. Commonly found in locations such as Morgan Hill, California, as well as various deposits globally.
