A vintage heart locket charm with a little gold vermeil square center that holds a gypsy set blue stone. The size of this locket allows it to be placed on a charm bracelet or it could be worn as a pendant. I am assuming that the stone is glass. The pretty heart opens to a compartment that I believe was specifically designed to hold a lock of arranged hair. It is an interesting raised circle with a real solid glass top and it must be pried open through a little notch on its side. It could also hold a photo but it seems to be intended for a memorial item such a little plait of braided hair. It is marked sterling on its attached bail and has no other marks that I can see. The charm measures 7/8" x 3/4" and weighs 4.1 grams. Don't let its clean look deceive you as to its age. It was very tarnished on the interior when I obtained it and I did clean it up so it presents nicely now.
