Don't store your diamond jewelry next to other jewelry pieces as this can cause scratches. A fabric-lined jewelry case with separate compartments is Ideal. You can also individually wrap jewelry in soft tissue paper or use jewelry pouches for each piece
Regularly inspect your diamond jewelry to make sure the setting is secure. Promptly bring it to a professional jeweler if you notice any signs of damage or loosening of the prongs. It's a good idea to have your diamond jewelry examined at least once a year by a professional jeweler. In addition to performing any necessary repair work, your jeweler can expertly clean your jewelry.
Everyday exposure to creams, skin oils, hairspray, household chemicals and other substances can cause buildup that will dull your diamond's brilliance and sparkle. Use a solution of warm water mixed with a few drop of ammonia in which to soak your diamond jewelry. Gentle scrubbing with an old, soft-bristled toothbrush is useful for more extensive cleaning. Rinse and dry with a clean soft cloth.
