(Yes, this means the definition is a moving target!FYI: Many antique dealers and collectors are currently snatching up Art Deco necklaces and other pieces from the 1920s.
For example, necklaces from 1915 through 2004 can be considered “vintage” in 2014.
Even collectors, bead artisans, antiques dealers and others who deal with vintage jewelry on a daily basis might not be able to scrounge up a “period” clasp.
Or they might not have the fortitude to undertake the task.
The following two charts on clasps contain helpful information to help you with your detective work: Important Clasp Developments: Prior to 1800: s-hook, hook, pin & barrel, slide-out (tongue-in-groove) clasp, toggle Circa 1840: spring ring clasp Circa 1890: screw barrel clasp Circa 1940: box clasp Circa 1990: magnetic clasp* *(note: A patent for a magnetic clasp was applied for during the 1950s but it did not see mass-market production) Common Vintage Necklace Clasp Types by Era: Early 1900s through the 1920s: pin & barrel, screw barrel, spring ring, hook, slide-out 1930s through the 1940s: spring ring, hook, fish hook, box, screw barrel, fold-over latch, slide-out, multi-strand 1950s through the 1960s: hook, fold-over latch, fish hook, box, slide-out, multi-strand 1970 through the 1980s: spring ring, screw barrel, fold-over latch, hook, lobster, toggle, fish hook, box, slide-out, multi-strand 1990 and beyond: lobster, trigger, magnetic, toggle, fish hook, screw barrel, spring ring, slide-out, tube (modern pin & barrel), multi-strand Of course, even with the helpful charts above, you must follow a few words of caution: None of the information above will help you date a vintage necklace if someone has replaced the clasp. Clasps are susceptible to corrosion and breakage over time.
This should not be surprising since clasps see more wear than the rest of a necklace due to continued opening and closure through the years.
You will learn to identify when a clasp has been replaced almost immediately upon inspection.
The clasp might look newer than the rest of the findings or be made of a different material.Unfortunately, this process is not straightforward. Original clasps are often replaced with inappropriate substitutes made from different materials and from different time periods.However, with a bit of study and awareness of what clasps were popular in different eras, you will be able to spot a vintage necklace with an improper clasp. As mentioned above, these elements include style, material and maker’s marks, if any.Just like true detective work, dating necklaces always requires piecing together several clues.Often, it will be the incorrect type of clasp for the time period in which the necklace was made.
