A modernist pendant signed JPA 925 made of sterling silver with a black polished oval onyx, inset into the front. It is possible that this is Mexican as I've seen other pieces signed like this without Mexican assay marks. It has a hook at the top that would accommodate a chain - no chain is provided. It measures 1 3/4" in width by 1 3/8" in height. It is in very good condition.Very Nice clean line to this piece, excellent quality.
