The Heliotrope colour of these crystals (named for the flower of the same name) is predominantly purple but also has flashes of blues, pinks, greens and greys. (The reverse side of each crystal has a metallic coloured coating which is what gives the crystal it's gorgeous colours.)
These crystals also have a special protective layer designed to protect the effects from scratches, fingerprints and other damage and also helps to prevent moisture damage that can lead to corrosion (example: from perspiration).
