FAQ'S ON THE GRAN COLORIMETER

1. How accurate is the Colorimeter?
A properly calibrated Colorimeter grades round brilliant cuts extremely accurate. At Good Old Gold we will test and double-check diamonds every day and the grand majority of the time it is very reliable and line up with the labs grade. If we see questionable results however we also check against master stones. This unit is now in it's 3rd generation and we've been using it since it was first released in the 1990's.

2. Can fluorescence skew the results?
This has not been our experience.

3. Does the Colorimeter work for fancy colored diamonds?
It does but not to the point of distinguishing the differences between the intensity of fancy colors (ie. Fancy, Fancy Dark, Fancy Intense, etc.). Below is a picture of a diamond that is a fancy brownish/yellow and it's correlating colorimeter results. Note the DC3000 rates it a fancy b-YELLOW for fancy brownish-yellow.
