Fashion jewellery (including plated, 925 Sterling Silver and expensive Jewellery brands) can experience normal wear and tear over time. To extend the life of your jewellery, please give them occasional breaks and to keep them away from any moisture and creams. Please follow these tips to maintain the quality and prevent early tarnish: Avoid sweat Keep them in your dust bag when not in use Wipe with soft cloth Do not sleep in your jewellery Avoid chemicals (especially hand cream) Avoid bathing, showering or washing your hands with jewellery on Wait for hand/face cream to dry before putting on any jewellery  Apply a layer of polymer coating/clear nail varnish on the inside of your rings How to avoid the Green Finger IMPORTANT: When accessorising your practice hands, get some clear nail polish and apply a layer of nail varnish to the inside of your rings to form a protective barrier between the ring metals and your practice fingers' skin. This will help prevent any green oxidation marks. IMPORTANT: Traces of copper will be found in Gold/Rose Gold plating as this contributes to the colouring of the metal. In some extreme cases of sensitive, highly acidic skin, you may experience some oxidisation (slight greening). The other main cause of oxidisation is chemicals found in hand creams. This is in fact a common trait in even the finest of jewellery. If you are allergic or sensitive to metals or have had green tainting before then you are likely to experience the same reaction.  All 925 Sterling Silver contains 92.5% sterling silver and 6.5% copper which may be a better option for you if have had green tainting before. We take no responsibility or liability for any reactions that may take place; It is the responsibility of the customer to ensure all precautions are taken as we are unable to know each individual's allergies and sensitivities.
