What Are Preciosa®'s Eco-Conscious Crystal Colors?
A look at the cadmium-free colors behind Preciosa's push for more sustainable crystal manufacturing.

Preciosa's eco-conscious crystal colors, including Red Velvet, Mesmera, Acid Yellow, and Vivid Siam, are cadmium-free shades developed since 2012 as part of a broader effort to reduce the environmental impact of crystal coloring without sacrificing brilliance.
As a Preciosa® Platinum Elite Authorized Partner, we've watched this initiative grow since it started, and it's changed how we think about color, not just how it looks, but how it's made. Here's what the eco-conscious line actually is, which colors belong to it, and how Preciosa develops a shade like this in the first place.
Quick Reference
| Program started | 2012 |
| Goal | Replace cadmium-based coloring agents |
| First cadmium-free true red | Red Velvet, 2018 |
| Newest cadmium-free red | Vivid Siam, 2025 |
| Crystal origin | Bohemian, or Czech, crystal |
01
Why did Preciosa move away from cadmium in coloring?

Cadmium compounds have historically been one of the most reliable ways to produce a true, saturated red in glass, but they carry environmental risk during production even when the finished crystal itself is safe. Preciosa began looking for alternatives in 2012, aiming to match cadmium's color performance using safer raw materials. That search has produced a small, growing family of colors developed specifically around this goal.
02
Which colors are part of Preciosa's eco-conscious line?
Four shades currently carry this designation, each developed under the same cadmium-free standard but with its own story.
| Color | Year | What makes it notable |
| Red Velvet | 2018 | The first cadmium-free true red Preciosa produced |
| Mesmera | 2022 | Made using recycled didymium, a circular-economy approach to color |
| Acid Yellow | 2024 | A bold yellow added to the same cadmium-free family |
| Vivid Siam | 2025 | The newest cadmium-free red, deeper and more saturated than Red Velvet |
03
How does Preciosa develop a new sustainable color?
Each new shade starts in Preciosa's labs, where chemists test alternative coloring agents and high-purity raw materials against the same three targets: true color, clarity, and lower environmental impact during production. It's a slower process than reusing an existing cadmium-based formula, which is part of why only four colors carry this designation so far rather than the full catalog.
Is every Preciosa crystal color cadmium-free?
No. Only Red Velvet, Mesmera, Acid Yellow, and Vivid Siam currently carry this designation. If a specific cadmium-free color matters for your project, whether for a body-adjacent application or simply as a sourcing preference, confirm the individual shade rather than assuming the whole Preciosa® line qualifies. Our color chart is the place to check before you order.

Frequently Asked Questions
What does "cadmium-free" mean for a crystal color?
It means the color was developed without cadmium compounds, which have traditionally been used to produce certain saturated reds and yellows in glass. The finished crystal is not the safety concern; the goal is reducing environmental impact during manufacturing.
Are cadmium-free colors as bright as standard colors?
Yes. Preciosa's stated goal for this program is matching cadmium-level brilliance with safer materials, and Vivid Siam and Red Velvet are both marketed as full-saturation reds rather than muted alternatives.
Is Preciosa considered European crystal?
Preciosa is Bohemian, or Czech, crystal, made in the Crystal Valley region of the Czech Republic. "European crystal" is a separate term we use specifically for our LUX line, so the two aren't interchangeable even though both originate in Europe.
What's the difference between Red Velvet and Vivid Siam?
Both are cadmium-free reds, but they're distinct shades. Red Velvet, introduced in 2018, was the first of its kind. Vivid Siam, introduced in 2025, is a deeper, more saturated red developed after Preciosa's process had matured further.
Does Rhinestones Unlimited carry these colors?
Availability varies by shade, size, and crystal line. Check our color chart or Preciosa collection for current stock before placing an order.
Does an eco-conscious color cost more?
Pricing depends on the crystal line, size, and quantity you order rather than the color itself. Check current pricing on the product page for the specific item you're sourcing.
