This necklace has molded sterling silver beads. They remind me of Navajo pearls with their mold marks and weight. The clasp says Silver Mexico but the beads do not look like any that I have had from Mexico. They test for Sterling Silver and have that more delicate look just like the Navajo pieces I have had in the past. Either way it is a beautiful vintage necklace. It is about 17 1/2" long and the beads are about 11.5mm. They are individually attached to each other. This necklace has old patina and is in excellent condition. I do not see any dings but could have missed something small. Weight is about 25 grams.
