Set of 3 rings size 5 with exquisite flower enamel detail on each.

Great for pinky ring set since size is 5 or wear individually. they are designer. they are silver, gold and rose gold color. worn maybe once. bought in jewellery store many years ago, but can't recall name and ring is not marked other than the flower enamel on each. does not tarnish. if anyone knows who the designer is please let me know!!
