The Bolton Ring - Size 7

Size 7 - NOT adjustable*

The Bolton Ring features a square Royston Ribbon Turquoise stone, on a double half-round band. 

Royston Ribbon Turquoise (also known as Boulder Turquoise) is found in the Boulder mine in northeast Nevada, USA.

*While some of my bands are adjustable, this one is strictly a size 7 and cannot be changed.
