Swarovski's growing crystals reflects on the beauty of a natural crystal. It comes in two sizes: the 26mm design, which features a decorative cavity, and the 36mm, which has a decorative clearance hole. IT is also available in two shapes, Rhombus or diamond shape and Rectangel. At the core of each, up to 500 hand-embedded double cones maximize light refraction. This prism is a site to behold and no picture does it justice.
