When choosing the perfect diamond, you will be confronted with an abundance of diamond certifications sources. It is important to understand that not all certification companies have equal standards when grading. It is the difference in grading standards that has caused confusion in the industry and distrust among diamond dealers. The following is information about some of the differences found in grading companies and what you can do to aide in the selection of the perfect diamond.
In the mid 1990s diamond certifications started getting popular as a way for a retail store to show that their diamonds were better than another store. As the years went on, many diamond grading companies sprung up to fill this new growing market. Even though the entire diamond industry used the 4Cs, there was no universal standard to say what is G color or how clear SI1 needed to be. It is this vagueness that plagues the industry today.

So, when you are looking at the information, use it as an opinion of what someone else thought and see if you agree. Questioning the information given will allow you to actively decide for yourself if you like what you see. Additionally, compare many diamonds not just 1 or 2. It is important to ask yourself if you like what you see. Just because GIA calls a diamond I2 does not mean it will be too included to be beautiful.
However, if one of the international EGL companies calls a diamond an SI3. For example, SI3 it may look worse than the GIA I2. Many in the industry agree that GIA, EGLUSA, HRD, IGI, and GHI are reputable grading companies. But the diamonds are still graded by people and people can make mistakes. Using the certificate information in conjunction with what you find beautiful will help you choose the perfect diamond.
