Physical properties

Formation & geological history

Forms as mineral deposits around volcanic fumaroles, especially in Indonesia’s Mount Papandayan area; age depends on the host volcanic deposits and is not determined by appearance alone.

Uses & applications

Used for beads, cabochons, carvings, and decorative collections; not typically an industrial stone.

Geological facts

“Bumblebee jasper” is a commercial name, not a true jasper variety, and may contain arsenic-bearing minerals; avoid grinding or inhaling dust.

Field identification & locations

The yellow-orange bands and dark spots are characteristic, but visual identification is not definitive. Most material comes from West Java, Indonesia; handle polished specimens normally and avoid making dust.
