Vintage slate grey pearls. They have not been tested, so I'm not 100%. But, they are heavy, knotted in between. One issue, there is one pearl missing on clasp. Not s big deal if hair hides it! Also, a beautiful brooch in grey faux pearls & rhinestones The rhinestones are brilliant! There is also a bale where you can make it a pendant on a necklace. Two gorgeous pieces. One price. xposted, thank you!
