Pink, purple and red color diamonds considerate to be one of the most extraordinary and unique diamonds in the world, their unusual color and limited availability make them very popular among jewelry lovers.
These color diamonds are much rarer than white diamonds and only a very small number of them are being mined each year. .

To achieve pink, purple and red colors, Diamond Traces turns to the coating process. In this process, a very thin film is placed over the pavilion [link to pavilion] of the diamond which imparts the color to the rest of the diamond. Hence, once the diamond is set, the colored coating cannot be easily damaged as there is no coating on the table [link to table]. The material is less than a millionth of an inch thick and does not alter the diamond’s weight for practical measurement. .

This process is the perfect solution for people who cannot afford to buy
these expensive diamonds, they are less expensive and much more available in the market so you can find them in most shapes
and sizes. This alternative can let you afford and own this luxuries jewelry in a reasonable price that will impress everyone, without
the need of spending your life savings.


The coated color diamonds are safe to use, and require no special attention under normal wear and tear. The color treatment is not subject to change over time. However, coated color diamond should not be exposed to temperatures over 65ºC (150ºF). So If you prefer you local jeweler to take care of your “annual checkup” like prong repairs, band resizing, cleaning, or any other service, please be sure to tell your jeweler that the diamond is coated diamond. Your jeweler will know to take the appropriate precautions.

Can be cleaned by:
  • Steam for only short amount of time.
  • Cold Ultrasonic for only short amount of time.
  • Gently scrub with a soft toothbrush and soapy water only the crown (the top) of the diamond.
  • Use mild jewelry cleaner.
Thing to avoid:
  • Exposed to excessive amounts of heat it might affect the color.
  • Do not expose the diamond to any acid (sulfuric or hydrofluoric).
  • Do not re-cut or re-polished your diamond.
The color of your coating pink diamond will last forever provided you hold on to these simple Do’s and Don’ts for proper care. For further information please contact our diamond expert or jewelry consultant at 800-343-4133 or info@diamondtraces.com.
