Bumblebee Jasper Properties, Facts and Photos
What is Bumblebee Jasper?
Bumblebee Jasper is a relatively rare stone from West Java, Indonesia. Despite its name, it's not a true jasper. Jasper is a variety of quartz, and scientific analysis has confirmed that Bumblebee Jasper contains no quartz.
The stone is also sometimes labelled as agate, which is also incorrect. From a geological perspective, although agate and jasper share similarities, neither are present in Bumblebee Jasper.
Many colourful stones used for decorative purposes are given trade names, and the suffix 'jasper' is always popular because of its familiarity. However, trade names often cause confusion when geologists try to determine the chemical composition of a specific material.
Bumblebee Jasper is widely reported to originate from Mount Papandayan, but further investigation has revealed that the mountain is simply a landmark close to where Bumblebee Jasper is found.
The claim that Bumblebee Jasper was found at Mount Papandayan initially confused geologists because limestone rarely occurs inside or close to a volcano.
It has since been confirmed that Bumblebee Jasper is limestone composed primarily of calcite.
The yellow and orange colour comes from the arsenic sulphide realgar but was initially believed to come from another arsenic sulphide called orpiment.
Orpiment and realgar form in the same environment and share similar physical properties. The black markings are believed to be manganese oxides.
Scientific analysis has shown that Bumblebee Jasper is high in sulphur and arsenic. Minerals with toxic elements are safe to handle, especially once polished. The danger comes from inhaling dust or microscopic fibres.
Cutting and polishing minerals with toxic elements must be done carefully and with appropriate breathing protection.
In Indonesia, Bumblebee Jasper is known as 'batu badar belerang.' This roughly translates to 'coal becoming sulphur.' Batu means stone or rock. Badar is related to coal, and belerang translates to sulphur.
An American rock and mineral enthusiast who discovered the stone while working in Indonesia named it Bumblebee Jasper.
Due to its popularity, vast amounts of Bumblebee Jasper have been mined. As a result, very little fine-grade material is now available.
