At this time our partner organization With This Ring facilitates the proceeds to charity, with Tangible Investments buying any and all usable gold jewelry at 95 – 120% of melt, plus the value of the gemstones.

We pay more for Tiffany, Cartier, and any major designer jewelry. Tangible Investments will pay all donors of With This Ring a minimum of $100 per carat for groups of small diamonds and wholesale rates on diamonds .5 carat or larger based on Rappaport guides.

Our prices will be very competitive for any larger diamonds and more than local jewelry and diamond buyers.

This program ensures the donation of all or a part of the proceeds to the charity of your choosing, and we provide you with a receipt so that you can write the donation off when filing your taxes.

Consign / Auction

We sell at all the major auction houses

Learn More

Our company founder and president, Silvano DiGenova, has literally traded hundreds of millions of dollars via auctions. As the former CEO of Superior Galleries of Beverly Hills, Mr. DiGenova led a team of professionals at the oldest and largest rare coin auction house in California. In 2005, the State of California entrusted him to be the official auctioneer for unclaimed property with a two-year contract.

Our highly-qualified team consists of awarding winning catalogers and rare coin specialists, and they experience and training at several world-famous auction houses, such as Sotheby’s, Bowers and Merena, and Heritage Auctions.

In addition, Tangible Investments buys and sells at all major auction houses throughout the United States, Europe, and Asia. We have a constant presence at auction firms such as Bonhams, Sotheby’s, Christie’s, IM Chait, Heritage, Stack’s Bowers, and many others. Due to the sheer volume of our auction business, we are afforded special rates and incentives rarely offered to individuals.

Whether buying or selling, it is in your financial best interest to speak with us first. We will select the proper venue for you, and provide you with a settlement package far better than you would receive by dealing directly with any major auction house.


Consignment Sales

Experience our auction house discount

Learn More

If you have ever bought or sold collectibles at auction, then you are aware of the fact that auction houses charge from 5% to 20% on both sides of the transaction. Because Tangible Investments transacts tens of millions of dollars per year with all of the major auction firms, we receive special rates not available to most individual buyers and sellers.

Usually your best bet is to sell to us outright. However, there are times when a major auction is the best venue for exceptional rarities. By consigning your valuables to Tangible Investments and allowing us to serve as your representative, you will net more at settlement time than by dealing directly with a major auction house. Not only will we guide you to the best venue, we will also share in our discounts so that you maximize the return on your valuables when it is time to sell.
