Established in 2002 and named for Laurelton Hall, the Long Island home of Louis Comfort Tiffany, Laurelton Diamonds is a wholly owned subsidiary of Tiffany & Co, and responsible for managing the company's worldwide diamond supply chain. Over the last two decades, Tiffany has transformed itself into a vertically integrated company that sources, polishes and cuts all its own diamonds. In an era when more and more people are paying attention to such things, this allows the company to achieve a level of transparency, traceability and accountability that had long been missing from the diamond industry.
