In rap, VVS refers to a high class of diamonds known for their clarity and quality. It is often used as a slang term to describe expensive and high-quality jewelry, particularly diamond-encrusted watches and chains. The term has been used by many rappers, including Post Malone, Cardi B, 6ix9ine, Kodak Black, Yo Gotti, Future, and Travis Scott. It is important to note that VVS is also a measure of diamond clarity, which grades the visual appearance of a diamond.
