The Eternal Limestones series is a rectified color body porcelain, manufactured in the United States. The manufacturer promotes green manufacturing processes and sustainable products. The Eternal Limestones series contains 21% pre-consumer recycled content. The beauty and extensive color variations in natural limestone are emulated in this series. Digital print technology imitates the distinctive intricacies of Lagos Blue, Jura Beige and Crema Europa limestones. Clean, recitified edges accommodate narrower grout joints which give the illusion of an uninterrupted honed surface with few visual breaks. This series is available in three earthy hues and includes a surface bullnose. Because this material is a porcelain product, minimal maintenance is required. When installing rectangular tiles 18 inches or longer with a staggered joint, it is recommended that the offset not exceed 33%. 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.
