A lot of beautiful products debuted at the Architectural Digest Home Show in March, but this three-dimensional stone tile took our breath away. Alternating matte and polished finishes give the appearance of two separate stones in a mesmerizing, undulating pattern. Ambra is available in Gris, Bianco Carrara, Lake Blue, and Moss Green, $45 to $50 per square foot, depending on type of stone, at Artistic Tile (65 Tarrytown Rd, White Plains 914-422-0041;
