Rhodonite Faceted Rondelles measure 3mm to 4mm in diameter, beads show a glass like luster with good polish and great good cut creating a symmetrical rondelle shape, these Rhodonite beads are well matched for a black and rosy Pink tone, and these beads exhibit an opaque body with a fascinating black matrix with a near metallic luster along with the rosy Pink Rhodonite hue. Beautiful!
