rings vary in size from a peace sign pinky ring (size 3) to some size 5, some size 6 and maybe one size 7. all are sterling silver except the spoon style rings with the round agates. they are plated and are adjustable. the unicorn ring and lady ring are both size 6. the wide ring that has an open front shown in photo 1 is a silpada ring that was originally $84 I believe.
