Perhaps a more accurate question would be what kind of estate jewelry do we buy? In a strict sense antique items should be at least 100 years old. However we are interested much more in quality examples of jewelry from such periods in history as Victorian, Edwardian, Art Deco, and Art Nouveau. Condition plays a very important part in value and any item that has undergone repair or alteration will command much lower prices han pristine originals. Even if your items are not in the finest condition they still may bring substantial from us. You might be pleasantly surprised how much that ugly bug pin is worth!
