Physical properties

Formation & geological history

Formed when silica-rich fluids replaced or cemented volcanic ash and breccia, with iron-bearing minerals producing the vivid yellow-orange colors. Bumblebee jasper commonly comes from Java, Indonesia, and is geologically associated with relatively young volcanic systems.

Uses & applications

Used for cabochons, beads, carvings, polished stones, and lapidary collections; it is not generally used as a major construction stone.

Geological facts

The name “bumblebee jasper” is a trade name rather than a strict mineral species, and some material contains calcite or sulfur-bearing volcanic minerals in addition to quartz.

Field identification & locations

Identify it by its opaque polished appearance, irregular yellow-orange/black patterning, and lack of translucency; it should not show the glassy transparency of agate. Commonly found in Indonesian lapidary material and metaphysical shops.
