Oval beads are hematine, gun metal. They are shiny, gray-black. The medium size is 5x8mm and there are about 100 beads. The small size is 3x5mm and there are about 50 beads. The strands are broken, so some are loose in the bag. They were purchased in Capetown, South Africa. Hematine (also magnetic hematite, hemalyke or hemalike) is an artificial magnetic material. Hematine is widely used in jewelry.
