An important factor that the NCDIA advises to consumers is to have all Natural Color Diamonds inspected when purchasing a piece. This will ensure that you are buying a diamond that is indeed natural and has not been treated.
In the marketplace, many black diamonds are in fact treated diamonds, although they can be found in nature. With the certification from a major gem laboratory, the origin of color should be listed as "Natural".
There's A Color For Everyone ...
Because Natural Color Diamonds are so rare, they are a great investment for any jewelry investor, collector or anyone looking to buy! These Natural Color Diamonds allow a buyer to express their own personal style by selecting the color that is right for them, or someone special.
Robert Lucien May, executive director of the NCDIA says, "A natural Color Diamond is a piece of forever with the excitement of color. It is the perfect gift of love, with a unique and colorful personality."
