Always store your jewellery carefully and separately to other jewellery pieces, to avoid damage and scratches to the surface. Ideally store your jewellery in the original box and away from chemicals or moisture. It is best to avoid wearing your jewellery in water or while doing an activity that might cause it to be scratched or damaged.
Cleaning your jewellery is best done by the person who originally made it. You are welcome to contact Amy to ask advise on cleaning your jewellery.
