This piece of mossy chalcedony can't truly be called moss agate since it has no plumes or dendrites in it. It has the shine of a nicely polished piece of chalcedony. Probably it was machine polished but we couldn't guess where it came from.

We got this tumblestone from a crystal collection which we bought from Facebook. It is one of a batch of nicer stones which we are glad came in because we have to few tumblestones.
