Similar to the extra little details that make luxury scarves stand out – beautifully crafted vintage costume jewellery will have interesting, decorative and secure clasps. In some cases the clasp is the most decorative part of the necklace. Often there is a brass hook with an extra trailing of beads or gemstones dangling from the clasp. In the case of multi-strand necklaces – there will be a decorative metal clasp, with the strands attached in rows on each side.
The hook clasps are the most common. I have seen a cylindrical bar clasp on a few bracelets, but the one shown in this post, is the only necklace I have come across that has one. It is a mix of crystal and chalcedony. The following are some examples of vintage necklace clasps on some costume – and some sterling silver necklaces. The first example is a classic vintage Oscar de la Renta very realistic string of pearls with a purple art deco clasp. A good tip to pass on for collectors and vintage enthusiasts – is to check the clasps on a rack of necklaces as a shortcut to finding the authentic vintage ones.
