The Design Gallery, hosted on the Internet luxury goods site adiamondisforever.com, added seven new diamond jewelry collections from new participating manufacturers in June. The new manufacturer participants are Andrew Meyer, Oxygen Design, Chad Allison Couture, The Stuckey Company, HQ Woman, Vassi Inc., and Leddel International.
