Diamond Cutting
A skilled diamond cutter creates converse, bright and even patterned detail and precision. When examining a diamond cut, start with the diamond face-up. If one examines several diamonds which have high cut grades, there will be very little difference amongst the stones. A compromised cut could be noticed by dark areas in the centre, under the table or around the girdle of the cut diamond.
The GIA system downgrades diamonds that carry excess weight in extremely thick girdles, steep crowns, or deep pavilions. Diamonds with features that make them vulnerable to damage – like extremely thin “knife-edge” girdles – also tend to receive lower GIA cut grades.
The GIA Cut Grading System applies to the most popular cutting style – the standard round brilliant – and all clarities across the D-to-Z colour range. There are five cut grades: Excellent (EX), Very Good (VG), Good (G), Fair (F) and Poor (P). A diamond with an Excellent cut grade is very bright.
All the numbers you might have heard other people referring to – table size, crown angle, pavilion angle – work together to create the spectacular stone.
A grading report used in conjunction with your own visual observation will guide you to observe details. Although, each diamond is unique and is considered to have its very own ‘fingerprint’ that creates its originality as well as its true rare beauty.
