You are looking at a sterling silver .925 love letter pendant. This silver charm/pendant is an envelope with two carved hearts sealing the flap. This is a nicely detailed, double-sided pendant, with the silver hallmarks used as part of the floral decoration, stamp and address on the front of the envelope. This pendant is antiqued to bring out some of the features. The charm measures about 7/8 inch high (including the ring) by ¼ inch wide and weighs about 1.2 grams. This is a very cute pendant.
This pendant/charm has a ring that would fit a neck chain that is approximately 4mm in diameter or less, or it can be added to a charm bracelet. It would be a wonderful gift to remind someone that you care.
