Sapphire is a variety of the mineral corundum. It is a precious gemstone. Sapphire is a 5th and a 45th Anniversary gemstone.

Synthetic Sapphire: A synthetic sapphire crystal or “glass” is actually not glass at all. It is a very hard, transparent material made of crystallizing pure aluminum oxide at very high temperatures. Synthetic sapphire has the same hardness as natural sapphire gemstones, but without the colouring agents that give the gems their various hues.

Why Choose Sapphire Crystal Watch Glass?

Sapphire Windows are manufactured from single crystal sapphire, making them ideal for demanding applications (such as laser systems) because of their extreme surface hardness, high thermal conductivity, high dielectric constant and resistance to common chemical acids and alkalis.
