In my last blogs about the 4C’s of Diamonds, I talked about how diamonds are graded based on their “Color” and “Clarity”. In this blog, I will be going over how the third “C”, the Cut of a diamond is graded. There are two main elements that are taken into consideration when it comes to grading the Cut of a diamond. The first one refers to its outer shape and the second one refers to how well the diamond is cut into that particular shape.
Interesting Trivia: Most people, outside the diamond industry, believe that the Cut of a diamond refers to the shape of a diamond. However, a trained gemologist refers to specific cutting parameters that bring a particular shape to life with highest fire, brilliance and scintillation.
Based on classifications and nomenclatures followed by the diamond industry around the world, the Cut of a diamond is divided into five categories.
1. Excellent Cut:The design of this cut is such that it ensures every shard of light entering the diamond is reflected multiple times and in all directions, thereby literally setting the stone afire from within. Achieving the Excellent Cut requires exceptional expertise and craftsmanship.Excellent cut diamonds show equal dark and light shades, creating an impression of play of shadows and light.
2. Very Good Cut:Very Good Cut diamonds have slightly more flexible cutting parameters than Excellent Cut. When skilled craftsmen attempt to retain higher carat weight by slightlycompromising onthe light performance, the Cut becomes Very Good. Diamonds with Very Good Cut still show good deal of sparkle, brilliance and fire, but their price per carat is much lower than that of an Excellent Cut diamond.
3. Good Cut:Just like the Very Good Cut, Good Cut diamonds are created by sacrificing quality of the cut over carat weight of a diamond. Most of the size proportions of diamonds in this cut are quite broader than those of the Excellent or Very Good Cut as the target is to get maximum stone size rather than focusing on the light performance. Such diamonds are ideal for the more budget conscious buyers who want to have a pretty stone that is larger in size.
4. Fair Cut: A cut that is almost at the bottom of the grading spectrum in terms of quality and preference. The only aim of those working with this cut is to get the maximum possible carat weight out of the rough diamond. There is very little consideration given to the color or clarity of the stone. The value of Fair Cut diamonds is based largely on their carat weight.
5. Poor Cut: The lowest of cuts in diamonds. These diamonds perform very poorly when it comes to the light performance inside the diamond based on internal reflection and refraction. They are just stones that have been processed to look big. As the cut is not optimized, there can be multiple inner impurities as well as outer surface defects. For those only looking to own a gem that is called a diamond without any other specific considerations, these are the diamonds to buy.
