Antique Gold Filled over Brass Heart Locket Expansion Bracelet

Antique gold filled over brass heart locket expansion bracelet. Often times these are hallmarked with manufacturer inside the bracelet, this one is not. It may be marked behind the foil inside of the locket. I did not want to disturb the protector and foil for it is original. Heart is personalized with an engraved monogram. Herat measures 7/8" tall and locket snaps down tight. Looks like a child's bracelet when relaxed and has a circumference of 4 1/2. It will stretch to 8". My wrist is 6" and I am modeling how it looks.Weight: 33.4 grams. Some wear to the gold where you can see the brass.
