Pantone color: 13-4809 TPG | Plume
Nanostone consists of 25% spinel crystals artiﬁcially grown in a glass matrix of silicon oxide, aluminum oxide and magnesium oxide. Completely lead-free and ﬂuoride-free composition is the main advantage of our material. Nanostone is perfect for accurate imitation of precious stones of a wide color range, even unique colors which are not found in nature. Nanostone is passive to thermal destruction of the structure and surface, does not change color and fade even with a sharp thermal shock up to 1000 °C. In terms of hardness and optical properties, Nano is very close to amethyst and synthetic emeralds.
