When choosing diamonds, the most crucial sides to think about is the quality of cut from the gemstone. This, even more than along with and also the clarity of the diamond, determines the quantity of sparkle coming from the gem. A properly cut diamond may have well proportioned and well angled facets which precisely reflect and refract the sunlight whilst preventing any from prematurely escaping through the back from the gemstone.
Within a finished diamond, the widest the main diamond is called the girdle. The section below is known as the pavilion and the section over the girdle is named the crown. An engagement ring takes place in the setting by its girdle, therefore the crown is always that section of the gemstone that is easily visible within the ring. The top of the crown is the table.
The table could be the largest and a lot important facet of the complete cutting process because it is the key entry point for light passing in to the gemstone in fact it is the facet which lets out one of the most fire and sparkle. In the Round Brilliant cut diamond, the table is ideally 56% from the width in the girdle however proportion can increase dramatically up to and including massive 90% within the mirror cut.
In table cut diamonds, the table facet is formed in to a geometric square or square like shape, like a rectangle. This is unusual because the table facet of most cuts is round, oblong, octagon as etc. Even square shaped Princess cut gemstones have octagonal table facets as well as the square like Cushion cut, a rounded square table.
However, the geometric table facets of the actual Square cut and Baguette cut, themselves using the Oblong cut are not enough to make them true Table Diamonds. The reason being they are based on a step cut, the location where the facets along the pavilion are reduce steps parallel on the edges similar to the sides of the Pyramid. The perimeters of true Table Diamonds are reduce gently rounding facets not steps. This can help maximise the flicker of the gemstone.
