The Cost and Significance of Diamonds

When selecting expensive jewelry, probably the most main reasons to think about may be the quality of cut with the gemstone. This, even more than large along with the clarity with the diamond, determines the volume of sparkle from the gem. A highly cut diamond may have well proportioned and well angled facets which precisely reflect and refract the light whilst preventing any from prematurely escaping from the back in the gemstone.

Inside a finished diamond, the widest area of the diamond is known as the girdle. The section below is known as the pavilion as well as the section over the girdle is known as the crown. A diamond takes place in the setting by its girdle, hence the crown is that the main gemstone which is easily visible from the ring. The the surface of the crown could be the table.

The table is the largest and a lot important part of the entire cutting process which is the key entry point for light passing in to the gemstone which is also the facet which lets out one of the most fire and sparkle. In a Round Brilliant cut diamond, the table is ideally 56% in the width of the girdle however this proportion can increase dramatically up to a massive 90% inside the mirror cut.

In table cut diamonds, the table facet is shaped in to a geometric square or square like shape, say for example a rectangle. That is unusual as 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, even the geometric table facets of the real Square cut and Baguette cut, themselves using the Oblong cut are not enough to make them true Table Diamonds. It is because these are using a step cut, in which the facets down the pavilion are reduce steps parallel for the edges such as sides of an Pyramid. The edges of true Table Diamonds are reduce gently rounding facets not steps. This helps maximise the flicker in the gemstone.
