Authentic David Yurman Ring. I am the original owner and it is in good shape except for some wear on the back (as to be expected, see picture). Ring is approximately a 7. Measuring the widest part of the inside of the ring side to side = approximate 11/16 inches converts to 17.4625 mm which equates to an approximate 7 in ring size. .925 silver Ring has not been worn much and has been kept in a smoke free, dust free jewelry case.
