Home Jewellery Education Gemstone Care Gemstone Care Gemstone jewellery should be cleaned with a soft, damp cloth. Maintaining Brilliance With gemstone jewellery, you should generally avoid sudden temperature changes. If you have a very active lifestyle, you may want to refrain from wearing your gemstone rings and bracelets throughout the day. Some gemstones are very brittle, especially emeralds, whereas rubies have a hardness second to that of the diamond (which is 4-5 times harder). Clarity Enhanced Stones For colour or clarity enhanced gemstones, ask a Georgies Fine Jewellery professional about cleaning and repair for your gemstone jewellery. For more information about each particular gemstone, read our gemstone guide.
