About RSA

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.

Eco Friendly Oriented

Eco Friendly Oriented

Sustainability is also the mission of RSA. All our products are made through eco-friendly processes using renewable materials, recycling and continually improving the efficiencies of our plant energy and natural resource consumption.

RSA invests to produce its own eco-friendly energy.

Our partners

Our alumina powder crystallization furnaces (from alum) are the result of many years of research and development, and are the heart of our know-how.

The objective being the best standards of chemical purity, optical properties (absorption, emission, conversion & reflection), and mechanical resistance.

Companies support us in the development and design of our technological processes.

The mechanical design service allows us to save time in the development of our crystallization processes. The 3D modeling and drawing of our ovens is the last step before the production of the various elements that compose them.
