Have you been looking for unique and interesting pieces of jewelry for your collection? They're sometimes hard to find among modern jewelry. There are a few truly unique jewelry makers out there, but many of them are targeting a niche audience, one which you may or may not be part of. Even then, many follow modern jewelry trends, just with a few interesting twists on the matter.
You should look into vintage jewelry. While vintage fine jewelry tends to be fairly expensive, there's a lot of good quality costume jewelry from bygone decades that you can dig into. There's quite a variety to choose from. Every fashion trend had jewelry to go along with it, and a lot of what remains is truly unique and beautiful. Here are a few styles to look into if you're looking for vintage one-of-a-kind jewelry.
Art Nouveau and Art Deco
These tend to be categorized together, for some reason or another—possibly because they were close in time, or possibly because sometimes sellers confuse the two and it's easier to throw them together. The Art Nouveau aesthetic tends to be more sweeping, organic lines, while Art Deco is much more sharply geometric with bold lines and sharp corners. You may not recognize the terms, but once you see the art styles, you'll recognize them from where you've seen them in real life such as historical buildings or where their influence has been seen in films and so on. The Art Nouveau period was early 20th century (and the tail end of 19th), whereas Art Deco is solidly a 1920s fashion and art trend.
Within the Art Deco category, you may see some Egyptian revival pieces as well. The Egyptian revival (or one of them, anyway) took place in the 1920s as well. The jewelry sometimes has Art Deco elements, but not necessarily. Most of that jewelry tries to evoke ancient Egyptian art that people have seen. This revival was largely based on the excitement surrounding the discovery of a largely unspoiled Egyptian tomb, that of Tutankhamen.
If you want a blast from the more recent past, you can reach back into the neon brights of the 80s, which are kind of having their own little revival right now in pop culture. The bold colors and bright geometric designs are common in jewelry from the 80s. It also tends to be fairly chunky, and you will find a reasonable amount of Lucite—a type of acrylic resin—used in jewelry making of the time period.
