In choosing diamonds, probably the most important aspects to take into account will be the quality of cut of the gemstone. This, even more than the colour along with the clarity in the diamond, determines the quantity of sparkle eminating from the gem. A highly cut diamond can have well proportioned and well angled facets which precisely reflect and refract the lighting whilst preventing any from prematurely escaping over the back from the gemstone.
In the finished diamond, the widest the main diamond is known as the girdle. The section below is called the pavilion and also the section above the girdle is named the crown. A diamond is held in the setting by its girdle, hence the crown is section of the gemstone which can be easily visible in the ring. Ab muscles the top of crown will be the table.
The table will be the largest and many important facet of the full cutting process which is the main entry way for light passing into the gemstone in fact it is also the facet which lets out probably the most fire and sparkle. Inside a Round Brilliant cut diamond, the table is ideally 56% in the width of the girdle but this proportion can increase dramatically to a massive 90% from the mirror cut.
In table cut diamonds, the table facet is shaped in a geometric square or square like shape, say for example a rectangle. That is unusual as the table part of most cuts is round, oblong, octagon as the like. 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 issues with the actual Square cut and Baguette cut, themselves based on the Oblong cut are certainly not enough to make them true Table Diamonds. It is because these are according to a step cut, in which the facets along the pavilion are reduce steps parallel on the edges just like the sides of the Pyramid. The perimeters of true Table Diamonds are cut into gently rounding facets not steps. This assists maximise the flicker in the gemstone.
