Rhombs of lustrous, pink rhodochrosite, to 1.5 cm across are in turn partially covered by intense pink, translucent, prismatic crystals of pyroxmangite (a rare, manganese, iron silicate) to .5 cm in length. This is a really unusual phenomenon, to see both related species on the same specimen! But, clearly from the crystal habits here, that is what we have. Never seen before, ourselves... There are also tiny crystals of an unknown black minerals covering a fair amount of the viewing surface. There is admittedly some damage to the rhodochrosite here, especially at the upper-left, hence the lower price than you might expect.
