Lia Sophia Mixed metal stack ring set-size 7

Brand new with tags retired design Three hexagon shaped rings, gold tone, cooper tone and silver tone Cooper tone has no stones, the other two have stones on every other side. Can we worn all together or individually. Size 7 but because these are thick and stacked, I would suggest purchasing if you wear a size 6. Unfortunately I’m a size 7 and couldn’t fit the set.
