Colorless Diamonds Certificates

The diamond certificate is often called the fifth C, in reference to the famous 4 Cs. This says how important diamonds certificates can be.

"The diamond certificate highlights important pieces of information about the diamond."

It also points out the treatments that might have been done on the stone, such as laser drills and HPHT. Additionally, the document mentions the possible fluorescence of the diamond, and its color. 

In addition to the 4 Cs, a diamond certificate mentions the serial number that has been engraved on the diamond’s girdle, when there is one.
