Your skins natural oils help to form a barrier against oxidisation.If you find your item of silver jewellery blackens when you first wear it, follow the above method of cleaning with a toothbrush & warm, soapy water.Initial discolouration should fade within time. It isn’t clear why this can happen to some people’s jewellery, but from researching, it seems it could be attributed to medication, diet or even pregnancy! (If you are male, you can probably rule out the last cause).FinishesFinishes that are applied to our jewellery can alter over time, simply due to everyday wear. This is more applicable to rings and bangles; satin & frosted finished pieces may become shinier with wear and polished items can become slightly duller with time.
