Onyx is a semi-precious natural mineral. It is a kind of agate. Its unique feature is the ability to let the beams of light penetrate to the depth greater than 5 centimeters. No other noble natural stone possesses this feature in full. When decorating premises with onyx, the illumination is often used to highlight the special depth of the stone and its devastatingly beautiful structure. The color palette of this natural mineral is very rich and diverse: from the shades of green and blue to the shades of pink and yellow. The products made of onyx are sensitive to mechanical impact. In contrast to marble, onyx is more resistant to aggressive chemical agents. It is highly suitable for the decoration of bathrooms.
