Estate jewelry (or estate jewellery) is a term used, most commonly in a retail sense, to refer to jewelry and often timepieces which are part of the 'estate' of a deceased person. More correctly estate jewelry is second-hand or pre-owned jewelry, with the 'estate' appellation signifying that the item is antique, vintage or an otherwise considered a significant or important piece.
While all used pieces can be described as estate jewelry, dealers usually limit this term to jewelry that was made within the last 30 years. Although formally, age is not a determining factor when it comes to classifying estate jewelry. Popular eras for estate jewelry are Georgian, Victorian, Art Nouveau, Edwardian, Art Deco, Vintage and Retro.
