How Much is My Diamond Worth?

December 6, 2017

Diamond Grading Report includes an assessment of a diamond’s 4Cs – color, clarity, cut, and carat weight. (According To GIA)

Grading Diamond Color

Since light source and background can have a significant impact on a diamond’s appearance, diamond color is graded in a standardized viewing environment against color masters.

Grading Diamond Clarity

The preliminary grader carefully examines the diamond in order to identify clarity/finish characteristics and evidence of any clarity treatments such as fracture filling or laser drilling.

 

Grading Diamond Cut
 Excellent to Poor Cut Diamond Grading System assesses the diamond’s overall face-up appearance to predict the intensity levels of brightness, fire, and scintillation (the diamond’s sparkle and interplay with light). GIA also screens every diamond submitted to determine if it is synthetic.
 
Diamond Carat Weight Measurement

To determine diamond carat weight, the diamond is weighed using an extremely accurate electronic micro-balance that captures the weight to the precise fifth decimal place (the nearest ten-thousandth of a carat). An optical measuring device is used to determine the diamond’s proportions, measurements, and facet angles.
