In order to cut wholesale diamonds at the best angles to produce the most fire, much of the original GIA Certified Diamonds rough is lost, resulting in a great decrease in the diamonds carat weight.
Each beautiful ideal cut comes with a grading Certificate or Report from an internationally recognised, independent Gemmological Laboratory.
First the engagement ring is weighed in a vacuum. Next the colour is determined. The clarity is then estimated only after the GIA Certified Diamonds has been magnified by 10 times.
