Why to be cautious of heavy metals in jewelry and how we test them.

What are Heavy Metals and Why are They Dangerous?

Heavy metals, such as nickel, lead, cadmium, and mercury, are commonly found in the metal components of jewelry. Some manufacturers use them because they are cheap and easy to process. However, the problem arises when such jewelry comes into prolonged contact with the skin. It can cause various health issues – from rashes to serious allergic reactions.

In the European Union, strict standards (such as the REACH legislation) are in place that limit the content of heavy metals in jewelry and fashion accessories. The reason is consumer health protection – heavy metals can accumulate in the body and cause long-term problems, such as damage to the nervous system, kidneys, or other internal organs.

• Nickel: A common allergen; can cause dermatitis and itching.
• Lead: Associated with disorders of the nervous system and blood formation.
• Cadmium: Highly toxic; can damage kidneys and bones.
• Mercury: Penetrates through the skin; accumulation in the body can seriously endanger health.

Standards for Heavy Metal Content and Extreme Cases from Practice

When selling jewelry in the European Union, strict limits on heavy metal content apply to ensure consumer safety. These limits are set by REACH legislation and other directives. For some of the most commonly tested metals, the limits are as follows:

• Cadmium (Cd): maximum 0.01 % (100 ppm) of the total weight of the jewelry.
• Nickel (Ni): maximum 0.5 μg/cm² per week (release upon contact with skin).
• Lead (Pb): maximum 0.05 % (500 ppm) of the total weight.
• Mercury (Hg): use is prohibited in any concentration.

Despite these standards, during testing of some jewelry and fashion accessories, we recorded shocking values:

• Cadmium: On one tested piece of jewelry, we measured a cadmium content of up to 90 %. This means exceeding the permitted limit by an incredible 900,000 %.
• Nickel: Jewelry with nickel that, upon contact with skin, released more than 50 μg/cm² per week, which is a 100-fold exceedance of the norm.
• Lead: Lead content of up to 75 % in some samples, meaning the permitted limit was exceeded by 150,000 %.

These values are alarming and prove that uncontrolled jewelry can be extremely dangerous. Such extremes most often appear with cheaper pieces from unverified sources, where recycled material of unknown origin is used.

This is precisely why we perform thorough testing of all our products using a handheld spectrometer. At IZMAEL.com, you can be sure you are buying safe jewelry that does not endanger your health.

Measurement Using a Handheld Spectrometer – How Do We Determine if Jewelry is Compliant?

To be able to confirm (or refute) the presence of heavy metals in jewelry with certainty, we use a handheld spectrometer. This is a special device that, with the help of X-rays, can determine the precise composition of a material within a few seconds.

The procedure works by the spectrometer sending X-rays into the tested object (in this case, into individual parts of the jewelry) and then capturing the characteristic "reflections" of the rays, which reveal what chemical elements are present in the object. The result of the test is a clear analysis listing the content of individual elements.

At IZMAEL.com, we have invested several tens of thousands of euros in a state-of-the-art, handheld spectrometer. Thanks to this, we can guarantee that the jewelry that reaches our customers meets the strictest safety standards.

• Measurement Speed: One measurement takes only a few seconds.
• Accuracy: Can determine trace elements in minimal amounts (ppm).
• Safety: Handheld spectrometers use low doses of X-ray radiation, safe for the operator and the surroundings.

Why Do We Test the Same Jewelry Multiple Times?

You might be asking why it would be necessary to test the same jewelry repeatedly. The reason is that the material of jewelry can change over time. For example:

• Wear of surface finish: If a protective layer is applied to the surface, it may gradually wear off and expose the base metal.
• Contact with various substances: While wearing costume jewelry, reactions with cosmetics, perfumes, or sweat can occur, which affects the surface.
• Manufacturing variability: Sometimes we receive different production batches of the same model, which may vary in composition.

In practice, it has happened to us that we performed initial tests on a sample batch that was fine. After six months, we took the same type of jewelry from the manufacturer and found that it no longer met the valid standards. Therefore, checking at different time intervals is extremely important.

Why rely on IZMAEL.com?

Here at IZMAEL.com, we take quality and safety seriously. The investment in a handheld spectrometer worth tens of thousands of euros is clear proof of that. Thanks to it:

• We guarantee: that every piece of jewelry we send complies with European standards for heavy metal content.
