The Jewel Cut Flat Backs are lavish embellishments making them great for accessories, textiles, dance-sport, interiors, costumes and even electronics. The gem-like colors and elegant shapes bring “life” to everyday products. Swarovski 2303 Pear Shaped Flat Back shown here in 8x5mm Scarlet. Scarlet,a rich red crystal shade, has magnificent standout; there’s a hint of blue that is more subdued than Light Siam, but brighter than Ruby and Siam. Unlike other red crystals, Scarlet is available in larger sizes, with a homogenous color intensity throughout the foiled Round and Fancy Stones, Flat Backs and Sew-ons, as well as unfoiled Beads and Pendants. Most importantly, it has a significant ecological advantage: unlike Light Siam or Siam, in that it is cadmium-free.
