14k Gold and 9K Gold: 14k Gold and 9k Gold should be kept in a box or pouch between wearings to protect it. Wash by hand or with a soft brush/cloth. Use warm water and a mild dish soap, rinse and dry thoroughly.
Diamonds + Stones: To clean diamonds and stones, use a mild solution of water and soap and apply with a soft brush - an old toothbrush can work well here.
