The "CA" mark in a ring typically indicates that the piece is made from "carnelian," a type of chalcedony gemstone known for its reddish-brown color. In some contexts, it may also refer to a manufacturer or designer's initials. However, the specific meaning can vary based on the context, so it's important to consider the overall design and other markings present on the ring. Always consult a jeweler for precise identification.
