Here I have bezel set a 5mm Mother of Pearl cabochon on to a 2.3mm polished sterling silver band.

It has been designed as part of my Stack Ring collection, so can be worn alone, or as part of a set from this section: http://www.folksy.com/shops/Scape?shop_section=stacking_rings
I make each of these rings to order which will take up to 5 days to complete. Just let me know your ring size in the message to seller on check out in Paypal.
