Psilomelane Slab #572 Sold Out

Psilolemane is actually manganese oxide. Psilomelane or (Crown of Silver) is manganese oxide in cryptocrystalline quartz. This is messy material to cut and polish, but well worth it when your done. The cabochons are stunning,

Just a side note, I’m not sure where this is from Mexico or not. Plus I’m not positive its Psilomelane, but that’s what I have been told. Measurements are taken at the widest points and the slab was moistened with water in order to demonstrate how it would appear after polishing. I will combine shipping. If shipping charged are higher than the actual cost, I will refund the difference to you.
