This pair features nice rectangular rhodium silver tray with 9 pieces of small fiber optic glass in different colors. Looks very attractive and is suited for any occasion. 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. Check our stores for other varieties of catseye & fiber optic cufflinks to complement your shirts.
