Faceted Tourmaline These are lovely faceted Tourmaline pieces - available in a fair few different shapes, sizes, and colours. Tourmaline is a prized gemstone, due to its relative hardness and wide range of available colours - it also isn't too expensive. It looks great in silver but darker pieces are quite nice set in gold, too - especially the darker green stones. We sell Tourmalines sorted by colour - green, pink/red, and mixed. Mixed stones are literally that - a random mixture, similar to what you see in the photos attached to this page.
