Robin Egg Turquoise Ring

I just love this turquoise stone "Robbin's Egg" ring!! Quite the statement piece. The band is silver plate on copper. The stone is composite turquoise. The ring is in excellent condition. There are no scratches on the stone, some age related rubbing off of silver on band. size of stone: 1 1/4 x 1 5/8 inches in diameter. size of ring: 5/8 inch (16 mm) in opening diameter which translates to a 5 3/4 in ring size (Canadian and USA sizing)
