Tourmaline gemstones come in brilliant shades of pink and green, as well as black. Beads are often strung in alternating colors to give a variety of beads on one strand. "Watermelon Tourmaline" occurs when the gem is cut with both green and pink appearing in the same bead. Small rounds and chip beads offer the range of colors at a nice price. Delicate faceted briolettes work great for chandelier earrings.
