Antonio Pineda's chain necklace with the orb clasp is heavy at 135 grams and 17in. long. It is over a half inch wide at 9/16th's. Because it is rather square in it's shape it also has great depth and dimension. Hallmarks are on the orb clasp and were difficult to stamp a circular object but this one is more clear than most of these in this design. Perfect alone or to hang your favorite pendant from. Condition is collector and museum quality and is a published book piece. You know it is very special at first glance and is stunning on, just LOOK AT THAT NECKLACE!
