This looks like a plant fossil but it's actually manganese oxide, pryolusite, dendirtes on a piece of limestone. This stunning fern type pattern on a tan stone bezel set in sterling silver and argentium alloy. The alloy makes this ring allergy free, and anti-tarnish. It is the only one, and no size variations are available.
Length of stone: 3/4"
Height of bezel and stone off of finger: 1/4
