Crystal Agate Black Lux is an extraordinary semi-precious stone surface handcrafted in Italy. This sophisticated material features a moody, translucent gray palette, formed by meticulously assembling natural agate nodules. Geologically a variety of microcrystalline chalcedony, it showcases the stone’s signature concentric banding and crystalline centers that create a mesmerizing, multidimensional depth. Its high silica content grants it a Mohs hardness of 7, ensuring remarkable durability for luxury countertops and backlit feature walls. Interestingly, while the name suggests a deep black, the "Lux" designation refers to its incredible light-reflectivity and the ability to glow with ethereal brilliance when illuminated from behind.
