This choker was provided me by a previous guy, it has little to no wear. The chain and heart are both 10k white gold as its printed on it. Their are 18 small diamonds that make up the heart. This locket is modest in elegance and strong in construct. It currently rests in its Lugaro box. The information viewed on the receipt is: 10KW.3 oTW 18RBC 1.7 GM.
