When choosing diamond jewelry, probably the most important aspects to take into consideration will be the quality of cut of the gemstone. This, even more than the color along with the clarity of the diamond, determines the quantity of sparkle coming from the gem. A nicely cut diamond will have well proportioned and well angled facets which precisely reflect and refract the sunlight whilst preventing any from prematurely escaping through the back of the gemstone.
Within a finished diamond, the widest section of the diamond is known as the girdle. The section below is referred to as pavilion along with the section above the girdle is named the crown. An engagement ring takes place inside a setting by its girdle, so the crown is the fact that area of the gemstone which can be easily visible inside the ring. Abdominal muscles top of the crown could be the table.
The table will be the largest and many important element of the complete cutting process since it is the principle entry point for light passing into the gemstone and it is also the facet which launches probably the most fire and sparkle. Within a Round Brilliant cut diamond, the table is ideally 56% in the width from the girdle however proportion can increase dramatically up to a massive 90% within the mirror cut.
In table cut diamonds, the table facet is shaped in to a geometric square or square like shape, such as a rectangle. This really is unusual as the table facet of most cuts is round, oblong, octagon as such like. Even square shaped Princess cut gemstones have octagonal table facets and the square like Cushion cut, a rounded square table.
However, the geometric table areas of the Square cut and Baguette cut, themselves depending on the Oblong cut are not enough to be 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 on the edges much like the sides of a Pyramid. The sides of true Table Diamonds are reduce gently rounding facets not steps. This can help maximise the glint with the gemstone.
