Decoding Gold Hallmarks: Understanding LK18 and 1901 Inscriptions


Question
Can you tell me what the Hallmark LK18 means?  I'm assuming 18 K gold, but just wanted to be sure.  The white gold ring also has an inscription and a date of 1901.

Answer
Actually, I cannot tell you for certain about these marks. Like you, I would believe it to be 18k as that was a popular karat for old white gold.  Funny thing, white gold is said not to have been introduced to the consumer market until about 1912.  An engraving of 1901 seems a bit early but such dates as "when it happened" in the jewelry world are often a bit cloudy and cover a few years.

The best answer will come from a jeweler who will test the metal for karat. Call first since some stores do not have a jeweler to do the testing.  Best wishes with the ring.

God Bless and Peace.  Thomas.
