A perfect option for countertops, our specialty stone such as agate is highly resistant to etching, staining, heat, and UV fading. Agate is a common rock formation, consisting of chalcedony and quartz as its primary components, with a wide variety of colors. Agates are primarily formed within volcanic and metamorphic rocks. Individual stones are hand selected for their purity and then assembled by our experienced craftsman to create smooth, glossy mosaic slabs.
