EUC Brown stone necklace

EUC Brown stone necklace. Likely vintage. I don’t remember the trip on which I acquired this necklace but I believe it was in the late 1990’s or maybe early 2000’s. It’s a great fall accent and I’ve enjoyed it, but it needs a new home. It’s a long necklace so it can be worn as a single strand or doubled for a lovely shorter piece.
