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.Snake chainsSnake chains have an unusual semi-rigid form that can make them susceptible to kinking.Careful storage and handling is required to preserve the chains original shape. We suggest that your necklace is loosely coiled or hanging up to avoid being squashed or misshapen.
