Nebula Stone is a rather hotly contested crystal that has been discovered in Mexico, with almost all the online 'Nebula Stone' actually seeming to be mislabelled Kambaba Jasper - even from retailers insistent that it is Nebula Stone. Kambaba and Nebula Stone have very similar markings, and very similar chemical compositions, but whereas Kambaba is mainly a green base with black spots and can be found in Madagascar, Nebula Stone is inverted with a black base and green spots, and comes from Mexico. The reason for the similar appearance is believed to be due to their very similar volcanic origin - Kamaba is not fossilised algae as is commonly claimed, but instead a volcanic Rhyolite.
