The cut of a diamond determines how well it reflects light. When it is well cut, the light is reflected from one facet to another and is then dispersed through the top of the stone, making the diamond dazzling to the eye.
However, if a diamond is cut too deep, some of the light escapes through the opposite side of the pavilion, causing brilliance to be lost and the centre of the diamond to appear dark. And if the diamond cut is too shallow, light escapes through the pavilion before it can be reflected and again brilliance is lost and the diamond appears glassy and dark.
Types of diamond cuts
Cut is the hardest aspect for any diamond cutter or polisher to master and the Gemological Institute of America (GIA), the most respected of all diamond certifiers, assesses cuts on a scale ranging from Poor for the worst to Excellent for the best.
At Australian Diamond Brokers, we only stock Excellent cut diamonds that have been hand-picked to maximise brilliance. An Excellent cut diamond is your assurance that the diamond not only has maximum brilliance, but that all measurements including each and every depth percentage, crown angle and table percentage, falls within the Excellent range.
GIA is so strict in this regard, that if any of these percentages or angle measurements only score a Very Good, then the whole grading of the cut drops from Excellent to Very Good. And as certified diamond graders from the Gemological Institute of America and the Diamond High Council in Antwerp, Australian Diamond Brokers take our duty very seriously in showing and explaining to our customers why one diamond cut is superior to another.
