The Living Building Challenge also recognizes the standard in the Material Petal, Responsible Industry.
Genuine Stone® is defined as stone which has been harvested from its in situ position within the earth’s crust and fabricated without altering the natural fabric of the material. This includes, but is not limited to: granite, marble, limestone, travertine, slate, quartzite, sandstone, and onyx.
This does NOT include: engineered quartz surfaces, manufactured stone veneer, or other artificial building materials.
Cambria, Lapitec, Silestone, Caesarstone, Dekton, Neolith and other brand names may contain natural materials, but they do not fit our definition of Genuine Stone®.
