Vintage Spratling era reminding one of Aguilar, et al, hand tooled dense pin brooch with a 6mm green ish turquoise cab simply stamped: MEXICO SILVER. Although could be a higher content - the weight is dense as with many early pre assay jewelry. Early wide C catch. By one of Spratling's or Aguilar's contemporary silversmiths no doubt.
Just under 2 1/2" X 1 1/4" and just under 1/2 ounce on a postal scale. Rich unpolished pre owned vintage condition.
$10 USPS Priority/Ins/Track or Free with your USA Ck or USPS MO.
