Certified Diamond
Diamond certification is essential when you\'re buying a diamond and is
different from a jewelerˇ¦s appraisal, although the certification is
part of any appraisal. Many diamonds look the same, but not all of them
are going to be of the quality you might like. Diamond certification is
the written proof of a diamond\'s attributes. Without it, you have no
assurance that the diamond you are buying is of the quality you\'re
paying for. With it, you know the precise grading for each of the 4Cs ˇV
color, cut, clarity and carat weight, and, therefore, the diamond
value.
Certification gives you the information you need to assess a diamond\'s
value compared to other diamonds. It also allows you to make an
intelligent comparison with other diamonds either in the same jewelry
store or in another.
Diamond certificates are issued by independent gemological
laboratories, not your jeweler. There are several grading laboratories,
the most prominent being: the International Gemological Institute
(IGI); the Gemological Institute of America (GIA); the American Gem
Society (AGS); the European Gemological Laboratories (EGL) and GemEx
Systems.
When you buy a diamond, be sure to question the sales associate first
about the characteristics or attributes of the stone. Ask to see the
diamond certification that will accompany the diamond when you purchase
it. If you do some comparison shopping, you will note that the quality
of the diamonds each jeweler carries varies depending on the store.
A diamond certification will also give you indicators about other
diamond qualities, such as fire, brilliance and scintillation, also
called Return of Light. These qualities refer to how light is refracted
back to the viewer when held stationary or when in motion. The
certification will also give you a measure of the stones fluorescence.
These factors also impact the beauty and brilliance of your diamond.
