When shopping for a diamond, there is a TON of lingo… so we’re gonna break it all down!!

The 4 C’s are basically the grading rubric for diamonds! Carat refers to how much the diamond weighs. Color is graded on a scale from D to Z, D being the most bright and white. Clarity refers to how clear the diamond is ( it grades the amount, intensity and position of inclusions). This goes from flawless, internally flawless, VVS1, VVS2, VS1, VS2, SI1, SI2, I1-3. Cut refers to how well the diamond is proportioned. The scale goes from Excellent to Poor (but note that it’s only used for round brilliant diamonds). There are similar scales for polish and symmetry for other cuts. 

The word ratio refers to the length to width proportions of the diamond. AKA some people like to have different ratios (think about chubby vs long and thin oval cuts)! 

Fancy shapes are anything that is not a round brilliant! This is because the round brilliant is the standard shape!

“Faces Up” is another term you might hear often! Color is graded upside down… so facing up white means that when it’s facing upwards, it could be perfectly white and bright even if it has a lower color grade.
