About Us

Highkarat is an excellent online source for buying or selling estate jewelry, high-end watches, authentic designer jewelry and luxury fashion items. We guarantee the authenticity of every piece we sell. Our GIA-certified graduate gemologist and jewelry experts have a long standing reputation in the jewelry business and jewelry appraiser field. 


Many of us have jewelry we no longer need, wear or want. Highkarat 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., 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.

You may contact us at info@highkarat.com. We will supply you with a quick, confidential evaluation of the pieces you are considering selling. There is no charge or obligation for this service.
