Physical properties

Formation & geological history

Formed in hydrothermal volcanic settings, especially around fumaroles in Indonesia’s Papandayan area. It is a relatively recent geological deposit; the polished pendant is shaped from the natural material.

Uses & applications

Used mainly for jewelry and collecting; not generally an industrial or construction stone. Avoid prolonged skin contact or dust exposure because some material may contain arsenic sulfides such as orpiment or realgar.

Geological facts

“Bumblebee jasper” is not true jasper, which is silica-rich chalcedony; the trade name refers to its striking yellow-and-black pattern.

Field identification & locations

Recognize it by vivid yellow-orange bands with dark brown or black areas, often in polished cabochons. Commonly associated with West Java, Indonesia; verify seller disclosures and avoid grinding or inhaling dust.
