Knowing your jewelry and its history helps determine its value. With periods like the Edwardian era, Art Deco and Mid-Century design, it’s easy to misdate your vintage beauties.
The worth of an estate piece depends on what style is popular at whatever time the owner decides to sell. For instance, the Art Deco period has become fashionable again, so jewelry from that period is worth more because there are more potential buyers. Some classic styles are more resistant to the ebbs and flows of fashion, like pendent necklaces or single-stone engagement ring settings. A vintage piece that is out of fashion will rarely be worth more than the gems and metals of which it’s made.
