Since its founding in 1988 by partners Jeff Green and Mark Shredrofsky, Stone Source has become a major East Coast importer and distributor of high-end surfaces. The company regularly updates its inventory with new finds, and Green says that white Calacatta marble, countertop-friendly Basaltina and the volcanic green-gray Burlington are the hottest choices among the architects, designers and homeowners who frequent the New York headquarters and the Boston, Chicago, Washington, DC, and Philadelphia offices. The company also is a trusted source for engineered stone, ceramics and glass surfacing. (via Elements of Living)
