The Gemstones used in fine jewellery are naturally occurring durable substances and each one needs a degree of care during use and storage. The structure and composition of each one is different in terms of hardness, toughness, reaction to heat, direct sunlight, acids, cleaners, etc. Certain Gemstones can absorb chemicals which change their colour. Taking care of your Gemstone is very important and home maintenance is fairly easy once you know your stone. If you follow a few simple rules then they will last for many years still looking good. Whether your jewellery needs polishing, shining, repairing, Liali Offers Fix & Shine! Walk in with old or broken, walk out with new and glittering.
