This is from a friend’s mother‘s estate, and I am not sure that this is real turquoise or not and as far as content of metal the clasp is marked 925, but again, I’m not sure if this is silver or something else… The faceted glass stones I have no idea if they’re glass or actual stone… But they’re very pretty in the faceting is quite lovely and quite shiny measures. 18 inches from end to end… Monies from the sale, go to rescue dogs and cats in our area… We are not a 501(c) just a group of guys and gals, who love animals, and want to give them a second chance… We pay for all medical, including spay/neuter/vaccination/micro chipping/flea and tick control, and anything else they may need before carefully placing them into loving homes … The last three pictures on this listing is of the latest dog we are rescuing and she just had a broken femur on her back leg repaired to the tune of $3000. She was hit by a car and astray on the street… We believe every animal has a chance and we rescue one animal at a time… Every life matters.. items we sell are from friends and our own stuff which helps the free costs… We encourage you to visit your local animal shelter and save a life… Please adopt don’t shop… Peace out!
