This chunky Mid Century sterling silver ring was made by Mexican silversmith and artist Antonio Pineda of Taxco.  The ring was converted from a single cufflink and features a chunky three dimensional diamond shaped face with a moonstone cabochon accent; this particular moonstone only shows its adularescence from the side. This ring is a size 7 and weighs 11.5 grams. This piece is in great vintage condition with light wear and is marked and signed as shown.
