Coffin Gems® designs are made in your choice of  USA (and UK equivalent) Ring Sizes in Quarter, Half and Whole sizes. The prices of the designs include this sizing - up to size 9.
 
However, we do have customers who need a ring size in an extended size of 10+.  Unlike some jeweler practices, we do not "stretch"metal to achieve a size.  We cast the design in the exact size that you order.   
 
This lising is for those customers who need a size in excess of a size 10 to add to their basket when purchasing a ring design.
