The larger flower has pave stones. the middle ring is Silver and has a post set white pearl, 6mm, without damage and with good luster. Can wear 1-2-all 3 rings, they stack nicely up to each other and can be combined with other stack rings. Size 7. Good, gently used condition. See pictures for additional information.
