Overcoming Problems with Silver Jewellery Tarnishing
To keep your sterling silver jewellery from tarnish, you can also store each item individually in small bags or in a jewellery box with anti-tarnish tabs.
Do remember that if your skin reacts to silver, it may turn black due to the acidic nature of your skin, which is particularly noticed with earrings.
If you have this problem then an alternative to sterling silver may be surgical steel or titanium. Both are are options as they don’t tarnish and require very little maintenance, though neither are considered to be fine metals like sterling silver, gold or platinum.
To identify if your jewellery is made of sterling silver, you can look for a hallmark or stamp on the piece. The hallmark for sterling silver varies from country to country, but in the UK, it is usually a lion passant. You can also use a magnet to test if your jewellery is made of sterling silver. Sterling silver is not magnetic, so if the magnet sticks to your jewellery then you know that its not made of sterling silver.
If you are still unsure, you can take it to a professional appraiser or jeweller who can help you identify the metal content of your piece.
