Ceramic jewelry isn't made of the same type of ceramic that you would find in most craft stores. Jewelry-grade ceramic is also called titanium carbide. Titanium carbide is very hard and used in many industrial fields. This high-tech ceramic is used as a heat guard in space shuttles. Titanium carbide is scratch-proof and when it is polished, it takes on an incredible shine and maintains a silky smooth appearance for a lifetime. This is a big awesome ring, will stand out! Makes a wonderful gift for anyone.
