These earrings are made with beautiful gun metal grey Hemalyke which is a man made material made with similar chemical properties to hard to find hematite.I have natural hematite jewelry and you can not tell the difference. Hemalyke blends with almost any color. It is a shiney gun metal grey color. Each earring is made with six arrowhead shaped 17x15mm stones stacked on each other. They have silver plated leverback findings and measure 3.5 inches long.
