First discovered in Java, Indonesia in the 1990’s these brightly coloured Bumblebee Jasper round beads will certainly add a splash of colour to your jewellery making designs. It is easy to see how this stone got its name from its yellow and black banding reminiscent of bumblebees! Bumblebee Jasper is not actually a type of jasper as its name suggests, but is a fibrous calcite with banding of orange, yellow and black material which is formed from a mixture of volcanic lava and sediment.

Please note: bumblebee jasper naturally contains small amounts of sulfur and arsenic-bearing minerals. It's completely safe to wear as finished, polished jewellery, but we'd recommend washing your hands after handling the raw stone, avoiding any grinding or sanding that could create dust, and keeping pieces away from young children who may put things in their mouths.
