Jewelry Maker’s Marks: A Brief History To be considered an antique, a piece of jewelry must be 100 years or older, while vintage jewelry must be more than 20 years old to be classified as such. “Retro” jewelry refers to pieces made during the 1940s and ‘50s and are characterized by the use of large and colorful gemstones.
Compulsory Hallmarks 1 Sponsor/Makers Mark. This hallmark represents the registered company that produces, designs, or ships the jewelry. 2 Purity Marks / Millesimal Fineness Mark. The purity mark is one of the first signs to look for on your jewelry when purchasing or viewing jewelry. 3 Jewelry Identification Marks. 4 Town Marks.
The study of jewelry maker’s marks is a fascinating subject, steeped in history, culture, and art. Often overlooked due to their intentionally hidden location and diminutive size, the etchings found inscribed on a piece of modern or vintage jewelry offer a window into the “who, what, and where” of the piece – and are well worth a serious look.
At some point these were all destroyed, leaving us without this valuable historical reference. The Antique Jewelry University has an extensive Jewelry Maker’s Marks Database to which new marks are added every week.

14KB ~ COULD ~ Mean bonded. It doesn’t have to. I’ve had jewelry marked 14K RGP that was solid gold, not rolled gold plate, as the silly designer chose RGP as their trademark. Any solid gold item should be tested to ensure purity.

An example is a 14 karat gold wedding ring. It is 14/24, which equals 58.3% gold and 41.7% alloy. In most engagement rings the stamp in the ring is 14k or sometimes 585. Both of those stamps mean the wedding ring is 14 karat gold.
Gold plated or lesser quaity gold. _________________
