This Antonio Pineda necklace is composed of eleven diamond shaped pyramidal onyx stones which are framed by silver "X" links. The clasp is a tongue in box which is a silver pyramidal shape as well. It's a design which is rarely seen, and a superb modernist piece which is fully articulated and lays perfectly on the neck. It's difficult to measure, so I've shown it against a ruler. I would say it fits more like a choker necklace and is meant to be worn higher on the neck. Weight is a hefty 112.9 grams. Signed and hallmarked with the Antonio Taxco Crown, 970 Hecho en Mexico Silver, and the eagle assay 17. Collector quality.
