Daria de Koing

couture Jewelry

California Estate Sales and Auction Company. consigns, auctions, and manages both public and private sales for all types of fine jewelry including the California jewelry designer Daria de Koing.



Fine jewelry  collections  by Daria de Koing are successfully managed due to their one-of-kind, hand made sensibility. 

These organically made beauties won’t be found on the finger, neck, or wrist of everyone, instead they are each unique and showcase the beauty of natural stones both precious and semi-precious. In the case of Daria de Koing designs, she most often uses cabochon stones  to capture the unmodified beauty of each stone. She famously said that “unaltered stones allow her to paint with gems.”


Other fine jewelry that California Estate Sales and Auction Company regularly curates is Cartier, Bvgari, Black Star & Frost, Van Cleef & Arpels, Harry Winston, Fred, David Webb, Tiffany, and other internationally known brands. 

If a seller prefers a private sale it is important to know that California Estate Sales and Auction Company, unlike other estate sale firm, has an established network of collectors and investors around the world ready to buy fine gems and jewelry. Often CESAC already has a buyer for many items without having to market the item(s).  If quick sale is a priority, the private sale method is an excellent option over the traditional auction process.
