Things to Know about Diamond Cut
If you’re in the process of buying a diamond for an engagement ring, pendant or a dazzling pair of earrings – diamond cut grade is considered the primary quality when it comes the amount of brilliance and sparkle a diamond gives off. For a diamond to have fire, brilliance, sparkle and lustre, it all depends on the way it is cut from the rough. To make it simple we supply diamonds with a GIA cut grade – Poor, Fair, Good, Very Good and Excellent.
The diagram above shows the effect of different cut grades and their light reflection. The Ideal cut is marked as excellent, where the light enters through the top, reflects from side to side and bounces back out of the top of a diamond. This is the perfect symmetrical diamond for ultimate brilliance and fire. If the diamond is shallow the light basically leaks straight through the bottom, not giving a diamond the sparkle every girl wants. If the diamond is two deep the light will leak out through the sides, again with no fire. The symmetry grade also decides how well a diamond is cut by indicating how well the diamonds facets are aligned and the light return a diamond will have which in turn determines its sparkle. So, if you’re looking for the perfect, symmetrical diamond to dazzle in an engagement ring, we only recommend selecting a very good or excellent cut grade.
