Offered for your consideration is a vintage Sterling Puffy Heart Pendant. I think that it is Middle Eastern in origin because of the intense applied detail. The pendant is 1 1/4" with the bale by 3/4" wide. It weighs 11.6 grams and be sure to look at the third picture to get a sense of how pudgy it is.
It could also be used as a charm. In excellent estate condition.
