There are 28 stones engulfed in silver. Each stone is about 3/4" long and 1/2" wide in the center. It says Mexico and 925 I believe on the back and something else above that which I cannot read. The clasp squeezes into a slot on the other end of the necklace. It is heavy but not uncomfortable to wear and it lays on the neck nicely.
It is about 191/2" long and the diameter when closed is about 16". It is an older piece but I cannot tell you how old. There seems to be quite a lot of silver in it.
