Ceramic is a state-of-the-art material that is scratch-resistant and extremely lightweight. This popular black color is not plated, so it retains its rich color, unlike other alternative metals. Ceramic is non-metallic, which is great for those with allergies or those who work in fields where metal jewelry is not allowed.
