SAPPHIRE - SUPER PERFORMANCE WITH HIGH-TECH MATERIAL

Naturally occurring sapphire belongs to the corundum group and is a crystal with the chemical composition AI2O3.

As a sapphire, it is often blue varieties (barbel blue) but also green, yellow-orange or violet that are mentioned. The colour is influenced by the smallest amounts of dirt, and the substances that give the colour are most often titanium and iron.

Synthetic sapphire was first successfully produced in 1902 by the French chemist Auguste Victor Louis Verneuil. The flame fusion process he developed still bears his name today. At the time, the aim of this development was to produce coloured synthetic sapphires and rubies.

Thanks to its unique combination and exceptional physical properties, sapphire is suitable for countless applications. After diamonds, sapphire is the hardest and most resistant material, making it ideal for use in the watchmaking industry, as well as for high-performance technical applications.

This high-tech synthetic product is inert, transparent when polished, acid-resistant, has low electrical conductivity and, with a melting point of over 2000°C, is suitable for the most demanding applications requiring perfect precision.

Nothing can spoil the beauty of sapphire. Sapphire is virtually indestructible and resists virtually all external influences. Watch glasses and technical components made of sapphire are distinguished by their scratch resistance, their non-porous, shiny, polished surface and their complete transparency. A material developed for generations.
