The marking "1BB" on the inside of a ring typically indicates the ring's quality and composition. "1" often refers to the purity of the gold, with "1" denoting a higher karat, such as 10K or 14K gold. "BB" can refer to the manufacturer's initials or a specific design or collection code. Always consult a jeweler for precise information about specific markings.
