The Gemstone Series is a color body porcelain that is produced to emulate the look of slate. As a color body porcelain, the porcelain body and surface glaze are colored with the same pigments. The result is a glazed tile with consistent color throughout the body. Because this material is a porcelain product, minimal maintenance is required, while sharing similar visual characteristics of natural stone. It is available in three rich, earthy hues, each of which provides high tonal contrasts between pieces. There will be noticeable variations in color and movement between pieces. Therefore, it is important and recommended that a range of this product be viewed before finalizing a purchase.
