A complex combination specimen of the now famous find in Inner Mongolia - it features small clusters of orange roweite and a beautiful, well developed area of johnbaumite (white) with cahnite on the typical andradite (green) matrix. There is a lot to discover with a microscope as well, but it is notable as a good johnbaumite with roweite specimen without magnification. You'll also find magnetite on the piece. No damage. From the 2018 finds. Johnbaumiate is the rare arsenate analogue of Hydroxylapatite and was never know in this quality crystals.
