Since each gemstone has its own quirks, different care can be necessary for the traits of each particular one. For example, a diamond is extremely scratch resistant, but more likely to chip than jade would be. Pearls and coral are susceptible to damage from chemicals and even ordinary perspiration, so should be wiped clean after each use. Extreme temperatures and radiation from sunlight can crack opal and fade kunzite.

The following tips will help your jewellery treasures last:

• Ensure proper fit.
  
• Remove jewellery before bathing, sleeping, housework, gardening, and sports. Swimming in a pool might make your diamonds sparkle, but chlorine will weaken the gold setting.
  
• Separate pieces for storage using soft, absorbent fabric to prevent scratches and tangles.
  
• Store in a secure part of the home, in stable temperature and humidity conditions.
  
• Have adequate insurance, photos for reference, and keep jewellery pieces at home as well as with the insurance company.
  
• Be gentle when cleaning, and make the process compatible with each specific type of jewellery. For instance, diluted ammonia works for diamonds and durable minerals; but very mild soap and soft brushes are appropriate for pearls (allow the pearl cord to dry completely on a flat surface).
  
• Take your valuables to a reputable jeweller every six months for professional cleaning and inspection for stretched pearl necklaces, thin ring shanks, broken chain links, or possibly even ideas for restyling into a brand new look.

Unless your jewellery is always stored in a safety deposit box, pieces are likely to need occasional repairs. Choose a long-established jeweller with a reputation for integrity, fairness, and the competence to perform high quality repairs. Such a company will be staffed by well-trained and experienced people.

Typically, estimates are given within a few days, at no charge; and your valuables will be insured by the jeweller, when in that company's care. Be prepared to allow adequate time for the actual work - "rush" jobs, although convenient for customers, can result in sloppy/incomplete workmanship.

Finally, keep in mind, it is always less expensive to retip thin ring claws or tend to stretched link chain links, than it is to replace a lost gem or necklace. Preventative maintenance is money well spent.
