About Spring Ring Clasps
A spring ring clasp is a type of jewelry clasp that works by opening and closing a metal jump ring with a spring-loaded mechanism. To use it, you simply have to push
down on a small tab that compresses the spring and opens the ring. Releasing the tab will automatically close the ring. Spring rings are popular for bracelets and choker
necklaces, and their size works well for jewelry strung with small beads6. They are easy to use and can commonly be found in necklaces, bracelets, and anklets.
Inexpensive gold and silver colored spring rings are usually made from base metals such as brass, copper, or steel, and then plated with a thin layer of gold or silver.
These clasps are not very durable and can tarnish or wear off over time. For higher quality clasps, you can look for ones that are made from solid gold or silver, or from
other materials such as stainless steel
The exact origin of the spring ring clasp is unclear, but it is believed to have been invented in the late 19th or early 20th century. It was patented by F.B. Hayward
in 1911 as an improvement on the existing spring ring clasps. Spring ring clasps became widely used in the 1920s and 1930s, especially for Art Deco jewelry. They are
still one of the most common types of jewelry clasps today.
