Vintage Sterling Silver Oval Flower Locket Necklace

Large 925 repousse locket pendant is marked 925 and measures 1 3/4 inches, including the bail, by 1 inch wide.  It is on an 18 inch sterling silver chain and the weight of the necklace is 12 grams.  It is in great vintage condition.  I will point out that the hinge is on the right side as opposed to it being typically on the left side.
