black and white statement ring

This statement piece includes two stones that were found on the shores of Lake Michigan in Chicago.  Both were found on the same walk, and are meant to be together.  Stamped accents and a split band complete the design.

Materials: oxidized sterling/fine silver, unknown stones

Note: these stones are unknown and have not been treated at all.  The white stone is very soft and porous (think pumice stone).  Both stones clean easily with a spongey nail buffer.
