This is a common occurrence caused by a reaction between your skin and the metal alloys used in silver jewellery. Most sterling silver is 92.5% pure silver mixed with 7.5% other metals like copper, which can oxidize when exposed to moisture, sweat, or certain skincare products. The green residue is a harmless copper compound.
Is the green mark harmful?
No, the green mark is not harmful and can be easily washed off. It’s a natural reaction and does not indicate poor quality jewellery.
Why is it more noticeable under rings?
Sweat tends to accumulate under rings, creating a moist environment that accelerates the reaction between your skin and the copper in the silver alloy. Rings are also in constant contact with your skin, which increases the chances of residue forming.
How can I prevent green marks from silver jewellery?
Here are some practical tips:
- Keep your jewellery dry: Remove rings before washing your hands, swimming, or exercising to minimize exposure to moisture and sweat.
- Apply products first: Ensure skincare products, lotions, and perfumes are fully absorbed before putting on your jewellery.
- Clean your jewellery regularly: Wipe your silver pieces with a soft cloth after wearing them to remove any buildup of moisture or residue.
- Use a jewellery sealant: Applying a clear protective coating to the inside of rings can create a barrier between your skin and the metal.
- Opt for rhodium-plated silver: Rhodium plating provides an additional layer of protection, reducing oxidation and tarnish.
What’s the best way to care for silver jewellery?
- Store it in a dry, airtight container or anti-tarnish pouch when not in use.
- Avoid prolonged exposure to water, chlorine, or chemicals.
- Polish regularly with a soft cloth or a silver polishing cloth to maintain shine and prevent tarnish.
- For heavily tarnished pieces, use a mild silver cleaner, but avoid abrasive materials.
Does everyone experience green marks from silver jewellery?
Not everyone will experience this reaction. Factors like body chemistry, the environment, and how often the jewellery is worn can all influence whether or not a green mark appears.
