Diamond Cut
When buying a diamond the diamond cut is the most important aspect as this is what
determines the sparkler (fire) and the way the light reflects from diamond.
The cut is different for each of the shapes; the most popular diamond shape is the
round brilliant diamond. There have been mathematical formulas to determine the
cut grade and the GIA publishes what ratio there diamonds are classed in.
GIA has a cut chart which ranges from Excellent -Poor. Obviously the Excellent cut
is the best.
If you ask why is it so hard to cut a diamond well a round diamond has 58 cuts which
if all cut in proportion will reflect the light and make your diamond sparkle from
one side of the room to the other.
