When buying gold jewelry, it stated 14K, but on the jewelry itself it said 14KJJT. What does that mean?

Answer 1

The hallmarking (stamping a karat mark on a piece of jewelry) of jewelry is regulated by the FTC in the United States.

In the U.S., a piece of jewelry cannot be legally hallmarked unless it also contains a maker's mark identifying the manufacturer or maker of the ring.

JJT would be the maker's mark identifying who made the 14k ring.

A maker's mark on a hallmarked piece of jewelry is for the consumer's protection. It is understood that the maker is willing to stand behind the assertion that the piece is indeed 14k gold.
