Nordstrom Black Stone Silver Ring

Purchased this cute black stone ring at Nordstrom’s a few years ago. I am not 100% sure on the size, but I believe it to be a 6.5 as it is right on my size 7 finger. The stone is a matter black (almost gray in some lights). It has scratches and nicks on the sides as seen in the photos. Please comment with any questions. ALL SALES ARE FINAL!
