Gunmetal is a trio made from sterling silver in a serrated bezel. The stone is a hematite and quartz diamond shaped doublet. This creates a unique and edgy necklace for every day or a statement piece. There do happen to be gunmetal earrings that match and can be added on to this set for $30 extra. This is a special price because when you buy them separately, the earrings are $40 by themselves.
