I have an unusual Mexican mark on a pair of cufflinks which have a silver figure of what I think is a cow, and a background of a granulated blue stone. The mark, as I read it says Cristal Feenix, then there are a pair of triangles separated by a curve, like the upper portion of a cats head, and with and F in one triangle and a D in the other. Then something I cant make out and Mex. 925 Sterling. Any clues gratefully received.
Thanks.
