Technically containing zero jasper (despite its trade name), the orpiment and realgar (arsenic minerals) compose the orange/red, manganese and pyrite the black/grey, sulfur the yellows, and the white is calcite. Toxic in its rough form, cut, shaped and polished using protective equipment, but safe to handle and wear in its final polished form, like this cabochon I made here. 😊 NFS

Typically, this agate after barite pseudomorph is an extremely monochromatic white (with varying shades of grey), but rare colors found their way into this particular piece via iron oxides, which gave these slabs some very unique and unexpected character.

Blue Forest petrified wood from Wyoming. An amazing skin of botryoidal chalcedony wraps almost entirely around the circumference of this petrified beauty! Highly fluorescent under UV light, with what appears to be a honey colored calcite crystal hiding in the bottom of the blue and gold botryoidal cave.
