Circles in a Circle...pendant on circle chain

Lovely handmade circle charm necklace in sterling silver.  Circles cut out of pendant allows the darker oxidized interior to show through.  18" long sterling silver chain is made with numerous tiny circles connected with even tinier tiny jump rings.  Chain is deeply oxidized to match interior of pendant while the outside has a lighter oxidation.  Lovely contrasts of size and patina, all in circle theme.  

Charm is 3/4" in outside diameter
