A wonderful vintage Siam sterling silver brooch. It's a stylized diamond shape, and features two goddesses on it on a background of white enamel. White is one of the more rare colors to find on earlier Siam silver pieces.
Marked "Amfarco, Sterling, Made in Siam". Measures just under 2" long. Some tarnish.
I am always happy to answer any questions or send more photos when needed.
