This handmade Black Jack Turquoise Heart Ring in Sterling Silver is the perfect gift to show someone how much you care. Made in my studio in Norman, Oklahoma it features a textured single band perfect .  Black Jack turquoise is uniquely identifiable by its black rock surronding the turquoise seam. This provides beautiful contrast to the green turquoise seem located within the black rock. All of my pieces are one of a kind and are never duplicated.  Ring size 8 1/4 US. It can be resized up to one half size larger.
