Cut - Canadian Star Diamond Information
People often confuse the cut of the diamond with the shape of the diamond. However the shape selected is a matter of personal preference. The cut refers to the polishing, proportions and symmetry of a diamond, ultimately determining a stones brilliance and radiance. As a result a well cut diamond is regarded as more beautiful and brilliant and consequently more valuable than a poorly cut diamond. Many experts believe that cut is the key component in selecting a diamond, even more so than color and clarity, because a poor cut diamond will lack the ideal reflection and refraction of a well cut stone and not hold the same brilliance. In order to maximize brilliance, diamonds are cut within a range specified proportions.
Ideal Cut / Excellent Cut – Premier quality which reflects nearly all light that enters the diamond. An exquisite cut, which is only given to less than 5% percent of cut diamonds.
Very Good Cut- Reflects nearly as much light as an ideal cut, however at a lower cost. Approximately the top 15% of diamonds fall within this category.
Good Cut- Reflects the majority of light that enters, commonly use to maximize diamond size. Generally much less expensive than a very good cut, and accounts for approximately the top 25% of diamonds based on cut.
Fair Cut- Still a good quality diamond however primary focus is weigh maximization and not light refraction, hence a fair cut will not be as brilliant as a good cut. Approximately the top 35% of diamond quality based on cut.
Poor Cut- This includes all diamonds that do not meet the performance standards of a fair cut. These diamonds are generally deep and narrow or shallow and wide and tend to loose most of the light out of the sides and bottom.
