The American Gem Society (AGS), which is an association
of retail jewelers, inaugurated a new diamond-grading laboratory in
1996. The members of this society have ever since supported the Ideal
Cut Diamonds, which was first proposed by gem cutter Marcel Tolkowsky in
1919. His proposal for the Ideal cut diamond was based on a specific set
of proportions for a round brilliant diamond.
However, AGS went a step further and developed a scale of 0 to 10 to determine the grade of a diamond. It was decided that Ideal Cut diamonds is to be graded as 0. So to speak the AGS 0 enlists the following ideal proportions that includes the table diameter being 53% to 57.5%; crown angle being 34º to 35º; crown height should be between 15% and 16.2 and the diamond’s total depth should be 60% to 62%. Apart from AGS, there was another factor that increased the popularity of Ideal Cut Diamonds. This was the diamond viewing mechanism called Firescope. This devise pierces a red light into the diamond thereby creating a patter of reflections in accordance to its facets. This devise determines the symmetry of the diamond that is under scrutiny. The symmetry, polish and proportions largely determine the price of an ideal cut diamond. Thus, craftsmanship is of utmost importance. All-in-all Ideal cuts are stunning and fine-looking diamonds. These cut diamonds are not only smaller than a standard cut diamond; but are also longer and thinner. ~ author Karishma Bajaj.
