Jewelry Heavy Metals Testing

Necklaces, earrings, and rings in gold, silver, and platinum certainly look pretty but how safe are they?

With the advent of Mother’s Day, we were reminded that all costume, and fine jewelry may contain toxic metals. To avoid poisoning mothers and mothers-in-laws around the world with unsafe jewelry gifts, artists, designers, manufacturers, and stores are required in the United States to test for toxic metal content.

So what are toxic metals and why should you be worried about ensuring there are no toxic metals in jewelry that you sell, design, or manufacture?

Heavy metals are naturally occurring elements that have a high atomic weight and a density at least 5 times greater than that of water. While there are many heavy metals, the US National Institutes of Health (NIH) in an article entitled Heavy Metals Toxicity states that arsenic, cadmium, chromium, lead, and mercury are the most significant for their toxicity to humans. Heavy metals’ toxicity is influenced by various factors such as dosage, exposure, age, gender, and genetics. These metals are systemic toxicants, and even low levels of exposure can cause damage to multiple organs, leading to cancer.

In the US, jewelry is sold as costume jewelry and fine jewelry. Fine jewelry is defined high quality pieces made with precious metals and genuine gemstones. Costume jewelry is generally made with less expensive materials and may include imitation gemstones. Each category of jewelry can be made into rings, necklaces, earrings, pendants, watches, and body piercings. To ensure all jewelry is safe, a variety of testing can be done to show they are authentic and safe. Some of the testing required is for heavy metals content.

Atomic spectrometry is a popular method for analyzing trace metals in various samples, and different instruments are chosen based on factors such as cost, sensitivity, and regulatory requirements. To measure lead or cadmium in jewelry, labs use a test that combines acid digestion with Inductively Coupled Plasma (ICP) analysis, which turns the sample into a mist and injects it into a plasma flame.
