This is an authentic David Yurman 7mm Sterling Silver and 18k Diamond Buckle Bracelet. It measures 2 1/4 inches on the inside diameter and will fit wrists up to 7 1/4 inches around. The bracelet does have some flexibility so you can pull it wider to make it easier to put on your wrist. It is hallmarked on the back of the buckle DY and 925 and 750. I’m not sure of the current retail price but the version without the diamonds currently retails for $1850.
