A soft field of dove and frost grays is accented by darker, charcoal speckles in our beautiful Concerto Q-Quartz. Concerto Quartz countertops are an excellent option for decor that uses gray as a focal color, or for one which uses gray to highlight other more dramatic hues. On countertops, walls, floors, and more, Concerto quartz is perfect for creating a clean canvas with endless design possibilities.
