Online jewelry retailer Bidz.com sold all the intellectual property, trademarks and tools that it acquired in the bankruptcy auction of the Colibri Group to Richline Group, Inc., wholly-owned subsidiary of Berkshire Hathaway Inc.

The sold assets are of Krementz, Van Dell, Shiman, Dolan & Bullock, Taylor Avedon, Angelite, Skal, Skalet, Magical Years, Little Miss Pride, Sideways, Darling Diamonds, Fingerprint Locket and others.

Bidz.com also agreed in principle to buy future close-outs from Richline on a non-exclusive basis, the company said Thursday.

Richline is a U.S. fine jewelry manufacturer and the largest importer of gold jewelry. The major brands comprising Richline's portfolio are Bel-Oro, Michael Anthony, Aurafin, AuraGem, Sardelli, Pace Designs, Prime Time, Alarama, ALA Casting, Gold Expressions, Town & Country Jewelry, and Baby Gold. The company manufactures and distributes precious metal jewelry products that are sold at thousands of outlets. The firm is a major worldwide manufacturer in the U.S., Italy, India, Israel, Turkey, Bolivia, China and the Dominican Republic.

Bidz.com acquired the assets, plus inventory, at the Colibri auction for $6 million in late March. Colibri, a manufacturer and marketer of century old heritage branded jewelry products, has been placed into receivership in January.
