Jewelry allergies are common, often due to nickel. Many people opt for sterling silver to steer clear of this metal. But is there nickel in sterling silver?
Let’s delve into this topic and uncover the truth!
Composition of Sterling Silver
Sterling silver, though an alloy, typically doesn’t contain nickel, making it safe for most individuals. It comprises 92.5% silver, with the remaining 7.5% primarily copper, which is less likely to cause allergic reactions.
Many countries require sterling silver to have a quality mark, like “925.” Precious metal jewelry in those nations must undergo testing by a government assay agency before being marked and sold.
Does Sterling Silver Have Nickel in It?
If you have a nickel allergy, you should avoid jewelry containing nickel. But is sterling silver free from nickel completely?
Generally, sterling silver jewelry is nickel-free. However, some may contain traces of nickel, especially if sourced from unreliable vendors. At JewelryLab, we provide detailed information about our jewelry components to help customers make informed choices.
Historical Use of Nickel in Silver Alloys
Historically, nickel alloys have been commonly used for:
- Coins and ornamental objects
- Tableware
- Plated objects
- Costume jewelry
- Keys
- Doors
- Car radiators and hubcaps
Nickel Content Variations in Different Sterling Silver Alloys
These alloys, known as sterling silver alloys, owe their name to their appearance rather than their content. They are also known as nickel silver, German silver, or nickel-zinc. The composition of nickel silver typically includes:
- 60% copper
- 20% nickel
- 20% zinc
Despite the name, these alloys contain no actual silver but are named for their silver-like appearance.
Nickel-Free Alternatives in Sterling Silver
Considering alternatives for nickel-free sterling silver jewelry? Here are some options:
- Argentium sterling silver (94% or 96% silver)
- Britannia silver (95.833% silver, the rest usually copper)
Labeling and Certification of Nickel Content
Certain regions impose limits on the nickel content allowed in jewelry. For instance, the European Union’s Nickel Directive controls the amount of nickel that can be released onto the skin from jewelry. The directive mandates the following migration limits:
- 0.2 micrograms per cm2 per week for jewelry that is inserted into body parts.
- 0.5 micrograms per cm2 per week for other items that come into prolonged or direct contact with the skin.
The Importance of Verifying Nickel Content from Reputable Sources
A nickel allergy develops when the immune system flags nickel ions as threats. Typically, immune cells fight germs and harmful substances. When someone has metal hypersensitivity, their immune system reacts to the metal, causing various symptoms.
To avoid nickel in sterling silver jewelry, buy only from reputable sources. Those with sensitive skin or nickel allergies should be cautious of purchasing from unreliable vendors who might falsely claim their products are nickel-free. Be sure to check our best-sellers’ sterling silver options.
Conclusion
Does sterling silver contain nickel? Most sterling silver jewelry is nickel-free, generally containing copper as the supplemental alloy.
However, exercise caution when purchasing jewelry, as some pieces may contain nickel. Ensure you buy from reliable sources who transparently disclose their jewelry’s composition.
