If you are a fan of public television’s Antiques Road Show, you probably remember stories of Aunt Suzie’s broach or cousin Mollie’s bracelet or even that garage sale jewelry purchase that turns out to be worth hundred’s of dollars.

If the item were made of precious gems or mounted in platinum, you probably would not be surprised. But, these items are neither, they are costume jewelry. They may look just like something in that junk jewelry box that you let the kids use for dress up but, someone is willing to pay big bucks for them. 

Costume jewelry became a recognized category in the early part of the 20th century and referenced pieces that were designed for use with costumes. It was legitimized by major clothing designers such as Coco Chanel and Schiaparelli.

After the 1950’s, jewelry that was not precious, but was considered quality, was called fashion or designer jewelry. Costume jewelry is roughly divided into several time periods including: Art Nouveau Jewelry (1895-1915), Edwardian (1901-1910), Art Deco (1920-1935) and Retro (1940s).  

The value of a piece of costume jewelry depends on several factors. A primary consideration is the maker’s mark and many pieces of designer jewelry are marked. Names that should capture your fantasies include: Miriam Haskell, McClelland Barclay, DeMario, and Pennino, among many others.

You, of course, want pieces that are in good condition with working clasps and no missing stones. Beyond that, the value is determined by rarity, design, and originality. Although some older pieces may not be marked, their quality will be apparent in the design and workmanship.

There are many reference books dedicated to enlightening you about costume jewelry. However, the best on line site I have found is called Morning Glory Antiques Jewel Chat.

The host provides an extraordinarily well documented look at various periods and design pieces - all in full color. The article on jewelry marks and dates will be especially useful in comparing the necklace you found in your attic to ones that have collectable value.
