The Magic of Eco-Conscious Color Development

Not all glass coloring agents are equally eco-friendly. Some pose challenges during production, even if safe in the final product. Preciosa’s growing range of eco-conscious colors uses new formulas that eliminate harmful compounds like cadmium.

From the world’s first cadmium-free true red crystal to an upcycled violet shimmer, we’ve made color safer, smarter, and more sustainable.⁠

Creating new colors in glassmaking is both an art and a science—one that demands precision, innovation, and environmental responsibility. While traditional coloring agents often rely on heavy metals like cadmium, Preciosa has made it a mission to replace these harmful substances without compromising brilliance. Since launching its Eco-Conscious Color Development initiative in 2012, Preciosa has led the way in sustainable color innovation. A major breakthrough came in 2018 with Red Velvet, the world’s first cadmium-free true red crystal. This pioneering color proved that eco-conscious glassmaking could still deliver vibrant, high-quality results.

Preciosa continues to push the boundaries of sustainable glassmaking, showing that beauty and environmental responsibility can go hand in hand. The future of color is not only vibrant—it’s responsible.

Every new shade begins in the lab, where chemists explore alternative coloring agents, blend high-purity raw materials, and test each formula for color, clarity, and environmental impact.

This meticulous process has produced standout innovations like Mesmera (2022), made with recycled didymium, Acid Yellow (2024), and Vivid Siam (2025)—a bold, cadmium-free red that sets a new industry standard.
