When you are not wearing your jewellery, i recommend all sterling silver, gold vermeil, rose gold vermeil and Rhodium plated jewellery should be kept in a dark and dry place - ideally the jewellery box that your piece came with!
Precious metals can be affected by chemicals such as perfumes, body lotions and sun creams. Putting on your jewellery once you have finished dressing will minimise the effects of these chemicals. Any item that is plated will wear off over time but harsh chemicals will speed this process up, so avoid using anything close to your jewellery.
As a natural material, silver reacts with its environment, especially the chemicals in the air and, over time, silver does become tarnished.Skin and hair products can react with Silver causing it to tarnish, discolour and possibly corrode. I strongly advise applying any cosmetics and scents before you put on your jewellery!
Using a Silver dip solution might be beneficial for cleaning Silver items if they become tarnished.
To brighten up your jewellery, simply polish it with a microfibre polishing cloth or a specialist gold or rose gold polishing cloth.
