SELL YOUR JEWELRY
Many of us have jewelry we no longer need, wear, or want. High karat makes it easy for you to find out what your pieces are worth so that you can sell antique jewelry or make estate jewelry sales, no matter the era or designer of your piece.
We pay premium prices for signed designer jewels including Cartier, Van Cleef & Arpels, Bulgari, Tiffany & Co., and David Webb, among, many others.
We also buy unsigned jewelry from every era (Georgian, Victorian, Edwardian, Art Nouveau, Art Deco, Retro 1940s, and Mid-Century) along with modern designer pieces, watches, and other confections made of precious material.
