Natural fancy color diamonds achieve their coloring and special effects in several ways:

 

  • From different trace elements that are present in the stones. For instance, the presence of nitrogen gives us a yellow diamond.

     
  • From exposure to radiation during the diamond's creation. Green diamonds are an example of gems affected by radiation.

     
  • Inclusions, regarded as undesirable in a colorless stone, often contribute unique tones and interesting flashes in a fancy color diamond.

    Fancy color diamonds are more popular than ever, so gemologists have developed methods to create affordable versions by treating less desirable diamonds. Irradiation, followed by a high heat treatment, turns brownish and yellow diamonds into colorful show-stoppers.

     

    Treatments make it possible for more of us to own fancy color diamonds, because natural colored diamonds are rare and expensive. Diamond enhancements should always be disclosed, and you should assume that any affordable fancy color diamond has been treated in some way. If you question a stone's origins, ask for a lab certificate to verify its authenticity.

    How to care for your diamond jewelry

    Gems and precious metals are gifts of nature, which need special care. Even though a gem may be millions of years old, once mined and worn, it is exposed to conditions and chemicals that can damage it. The harder the gem, the less vulnerable it is to potential damage. A diamond, for example, is the hardest gem known to man, and that's one reason why "it is forever."
