Korálky Katlas collaborates with the Czech Environmental Inspectorate in the fight against fraudulent and hazardous jewelry.

Accurate, non-destructive, and fast analysis of jewelry metals, selected mineral beads, precious metals, and children's toys.

We were invited by the great people at Stoklasa. We prepared a presentation for them and provided training on how to identify fraud in the import of beads and jewelry components from China.

We will show you the real situation regarding the sale of genuine turquoise on Czech e-shops.

Korálky Katlas uncovered fraud in the identification of turquoise by Chinese manufacturers.

How easily fraudulent sellers can be detected.

We were shocked to discover that even certified suppliers with documented certificates provided a bead containing 65% cadmium. This is where the joke ends. It's literally a matter of life and death.

Not everything can be detected with a spectrometer. But what it does detect, you can trust. Other minerals are tested by a gemologist.

Take a look behind the scenes of mineral testing and discover what a spectrometer can reveal.

Why did we buy a spectrometer worth nearly 2 million CZK for regular quality control of beads and jewelry components?

In this video, you'll see discarded jewelry components that contained between 24% and 63% cadmium. We strongly recommend being extremely cautious if you decide to purchase such items—whether directly from China or even from sellers within the Czech Republic.

 Jewelry is beautiful, but it can often be dangerous. What is the reason?
