This is a necklace with a sparkling cut smoky quartz. The top also has a beautiful sparkling cut, but I believe it's glass, not a natural stone. It's a large stone, so it has some weight to it. Please check the last photo for the length. It has an adjuster, so you can adjust the length. I bought it several years ago and have kept it stored away, but there is no box, so I've listed it as "Like New." Perfect for going out or parties! Thank you.
