This was a gift given to me about 15 years ago that I wore maybe once. It’s in new condition and has been in its original box all this time. It’s from Sack’s Jewelry store in Jenkintown, Pa. which sells fine jewelry. I believe it to be a citrine stone, and it’s surrounded by delicate clear stones that are either CZ rhinestones or tiny diamonds. I took close ups of the clasp of the necklace and on the loop that the necklace goes through. The chain is 18” around.
