Very soothing 2 tone blue color fiber optic cufflinks mounted on silver frame. This pair features dark blue cat eye stone in the middle with 2 layers of light blue tone on either end. The entire combination is then covered with fiber optic glass and mounted on silver rhodium frame. Cat eye stone is gemstone that displays a thin band of reflected light on its surface when cut as a cabochon. Cabochon is a convex style of cutting gems. The optical effect, known as chatoyancy, is caused by the reflection of light from very thin, closely spaced filaments in parallel arrangement within the stone. Rhodium is a hard silvery-white metallic element that is highly resistant to corrosion. All this creates a very long lasting life for your cufflinks.
