Sterling Silver contains 92.5% Silver and the remaining is copper with a small percentage of other metals. Due to the presence of Oxygen, water vapour and Sulphur gases naturally occurring in the air, your sterling silver jewellery will eventually oxidize which is a natural chemical reaction. However, the 14k Gold/Rhodium plating on Sterling Silver keeps it long-lasting from this oxidation process.�You can take steps to maintain your Sterling Silver jewellery lasting for long! a) Avoid contact with substances containing sulphur such as eggs, mustard, onions, mayo, latex, wool, sulphur-dyed fabrics, sulphate-based shampoos, wood, cardboard and smoke�because it causes tarnishing. b) Wipe sterling silver jewellery with a special silver polishing cloth or a soft lint-free cloth to clean. c) Avoid exposure to chlorine/pools, hot tubs, spas, saltwater/ocean. d) Avoid direct contact with perfumes, hairsprays, lotions, sanitizers & household cleaning products as they can damage the plating. e) Occasionally clean sterling silver with warm water & mild soap. Rinse & pat dry with a soft cloth. f) Take off jewellery before going to bed to prevent the breakage of delicate parts. g) Store airtight in a sealed pouch/ box away from sulphur odours when not in use.
