This is a large pendant, 5.6cm in diameter. It seems suitable for both men and women. There is a marking, but it's unreadable. I believe the bottom line of the marking is the last four letters after "mexico." It appears to be made of a material similar to Mexican silver, with a moss green inlay. I suspect the motif is Mayan, Aztec, or Teotihuacan-esque. The brooch clasp is a hook type and lacks a stopper. I'm unsure if it's missing or if it was originally designed that way, as it was a gift. I don't have an opportunity to use it, so I would be happy to pass it on to someone who will. Please refrain from price negotiations. Thank you for looking.
