Bumblebee Jasper is a relatively new and rare mineral formed forms in volcanic environments in Indonesia. It has beautifully layered bands of black, yellow, grey and orange. This particular lot we purchased because we have never seen such deep saturated yellows and oranges before. That particular vein is now mined out, but we have this vein in a variety of shapes. Of particular interest is the jasper than contains no black, so you have a choice when purchasing the hearts. This is the prettiest bumblebee jasper we have ever seen.
