RSA has been creating crystals for over a century. Mastering crystallisation process for decades, we use only the highest raw material quality standards in the production of our crystals.
Concerned with guaranteeing the highest quality crystalline, RSA made the choice of integrating and controlling the entire chain of production. Water electrolysis, alumina powder production and crystallization ensure unrivalled purity and a superb range of colors with best light refraction, heat resistance and hardness.
