This necklace looks like tree branches with ice on them and is quite unique. The silver is soft and higher than 925. It is marked on the clasp and it reads PAZ and under that it reads MEX. It has no other markings and I had great difficulty getting a good photo of the mark and I will be adding more pix's for you to see better. There is no A or LA in the signature so I will let you be the judge. The necklace is almost 17in. long and a tad over .75in. wide. This is so gorgeous who cares who made it! A good solid weight at 2.5oz. Just, LOOK AT THAT NECKLACE!
