When choosing diamonds, the most crucial sides to take into consideration is the quality of cut with the gemstone. This, more than large and the clarity of the diamond, determines how much sparkle from the gem. A nicely cut diamond may have well proportioned and well angled facets which precisely reflect and refract the sunshine whilst preventing any from prematurely escaping with the back in the gemstone.
In a finished diamond, the widest part of the diamond is called the girdle. The section here is referred to as the pavilion and also the section over the girdle is termed the crown. A diamond ring is held in a setting by its girdle, so the crown is that section of the gemstone which can be easily visible from the ring. The very top of the crown will be the table.
The table is the largest and quite a few important element of the complete cutting process because it’s the principle entry point for light passing to the gemstone and it is the facet which launches one of the most fire and sparkle. In the Round Brilliant cut diamond, the table is ideally 56% of the width with the girdle however, this proportion can increase dramatically to a massive 90% within the mirror cut.
In table cut diamonds, the table facet is formed right into a geometric square or square like shape, say for example a rectangle. This can be unusual because the table part of most cuts is round, oblong, octagon as etc. Even square shaped Princess cut gemstones have octagonal table facets along with the square like Cushion cut, a rounded square table.
However, even geometric table elements of the Square cut and Baguette cut, themselves using the Oblong cut usually are not enough include them as true Table Diamonds. The reason being they are based on a step cut, the location where the facets across the pavilion are reduce steps parallel to the edges such as sides of your Pyramid. The edges of true Table Diamonds are cut into gently rounding facets not steps. This assists maximise the glint with the gemstone.
