This is a very interesting sweetheart bracelet as it is both a bracelet and a locket. It is 1/20 12KT gold over sterling. The top of the locket is made of white mother of pearl. On it is the US Army Medical Corp insignia. On the underside the locket opens to reveal two places for photos still with the original plastic covering them. The bracelet is stamped on the bottom part of the locket and also on the foldover clasp: P.R.S.T. Co. 1/20 12KT On Sterling. The locket measures 1 1/8" X 7/8". The length of the bracelet is 6 1/2". Excellent condition.
