This is an OLD Navajo necklace that has had some repairs made to it.  The repair person polished it, which we all know should not have been done.  Oh, well it gives it a little more life!  It is almost 11″ long which makes it a nice choker size.  The turquoise stones are a beautiful soft green.  I believe this was probably originally made for a child in the 1930s or so.
