I found a lovely pendant at a resale shop with only a .925 mark on the bale. Perhaps the workmanship, design etc. will look familiar to someone. I am starting with Mexican although I have no idea if it is. The pendant is round with intricate scroll work in the shape of spades that appear brassy in color. there are coral and turquoise stones throughout. The back is almost a mirror image of the front with minor differences. It weighs about 30 grams. Any help at all is greatly appreciated. Here is a link to the photos.
