50 piece pack of metallic two hole beads, each bead is approximately 6.4mm long x 2.9mm wide x 1mm thick. Holes are approximately 1mm wide, about 2mm between holes. Hematite is metallic black/grey and these beads have had a reflective shiny golden toned coating applied to them. Note that this coating doesn't completely cover the bead, creating an interesting two toned effect. Hematite is thought to be beneficial for those with health problems, particularly circulation problems. These beads are man-made, created out of a product similar to hematite, marketed as "hematine" or "hemalike". Please note that these beads are not magnetic.
