Approximately 4mm round peridot gemstone beads for jewelry making. India-Cut Peridot. These beads have been enhanced to bring out their natural beauty. Peridot splits and bends the rays of light passing through it, giving it a velvety appearance and rich glow. Gemstone beads from India tend to be made from high-quality stones, but their cut and polish tends to be less precise. As a result, these beads may be slightly irregular in shape with holes that are sometimes off-center, rough, and/or small.
