Due to our natural metals - gold and silver, your jewels will oxidise sooner or later. It is natural process, especially when you do not wear it for some time. To brighten your piece use a polishing cloth. Do not wash it with any chemicals or cleaning liquids.
As we use solid materials you can wear our jewellery all the time. But to prevent small scratches try not to wear your rings while manipulating with rough objects or surfaces.
In case you order 14K gold plated sterling silver 925/1000 styles, their plating will come off in some time. To prevent this try not to wear your jewelry while taking shower, washing the dishes or bathing. You can always re-plated them either you can ask us or your local jeweler.
