Smart looking D shaped laser engraved cufflinks set on a rhodium mount. This smart pair has 2 layers of black fiber optic with a layer of silver engraved in between. Guaranteed to smarten your personality! 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.
