Optix® is a revolutionary faceting method that causes gemstones to shimer and sparkle from all directions. Instead of a single reflection of light as in a regular cut, the Optix® cut creates multiple reflections which result in a superior scintillation, even colour distribution and added brilliance. Optix® is available in many coloured gemstones, but is particularly effective in light colour stones such as Amethyst, Aquamarine, Blue and White Topaz, Citrine, Lemon Quartz, Garnet, Peridot and Green and Pink Tourmaline.
