Round Brilliant diamond shape
The Round Brilliant is very similar to the classic Round diamond shapes that have dominated for decades. More precisely, Brilliant is the recent, stylish and supplemented version of the classical Round shape. The basic difference between these two diamond shapes is the fact that Round Brilliant shape has an ideal mathematical proportions which permits the diamond to perfectly reflect the light. Nowadays, the Round brilliant diamonds are definitely the most popular among other shapes. Ideal Cut gained popularity rapidly thanks to the most beneficial proportions of a cut. Perfect dimensions of a Round shaped diamond create a beautiful sparkle and fire to maximize overall brilliance. Cutting such diamonds requires more time to complete, which adds cost and complexity to the manufacturing process. Cutters are always trying to realize an optimal ratio of weight and shape to get the most out of rough diamond stone. Since Round Brilliant shape has been developed in the middle of 20th century it quickly became the most popular gemstone. Brilliant shapes gained huge popularity in a relatively short period as a result of sparkling glitter that left an effective impression on buyers. Today, Round brilliant shapes account for three quarters of all diamonds sold in the world. This diamond shape, due to high demand, suddenly became the most expensive piece of jewelry by breaking all the limits.
The mathematical theory of light reflection was applied to diamond cutting in 1919 when Marcel Tolkowsky in "Diamond Design: A Study of the Reflection and Refraction of Light in Diamond" specified a formula for an ideal shape in proportions and the size of the angles. This innovation has enabled a progressive cut of diamonds with advanced fire and brilliance that ordinary round shapes hardly had. Upgraded editions of diamond shape has offered a modern look to the diamond market and option to choose poorer 4c's parameters without a significant loss of perception about the quality to non-experts. Tolkowsky's ideal cut table size in comparison to the average diamond's diameter has standardized percentages between 53 and 58. The crown tilt angle ranges about 34% and the cone or a so-called pavilion measures 43%. The best diamond's depth or the length between the table and the culet for Round Brilliant diamond shapes are 59-62%. Few brillianteerers declared original measures too restrictive and made new mathematical formulas that determined some other dimensions. That has led to sharing the concept of an ideal cut among American and European style, but Gem Society set their own measurement limits for diamonds that are widely accepted.
Brilliant cut has a conical shape with slightly arched top known as the crown that spreads to the widest part of a diamond, girdle, and sharpens down to the peak or a culet. Over the years, the total facet number has multiplied. The first Round diamond, so-called Mazarins cut, presented by Ambassador J.C.Mazarin in the 17th century had 17 facets and a very simple shape, but still undeveloped enough. A century later, the number had increased to 33 in hands of Venetian brillianteer V.Peruzzi and held the same until geometry mathematics was applied to a new contemporary cut. Modern round brilliant diamond cut has 58 perfect flat surfaces accurately separated between the basic parts of the shape. The top of a brilliant diamond is the crown which consists of 16 upper girdle, 8 star and kite or bezel facets. The crown is positioned on the cone or pavilion. The pavilion has 8 main parts and also 16 lower girdle facets. Girdle is the widest segment, the maximum diameter of the round diamond split into upper and lower sections. All together with the culet at the bottom and table at the top that's 58 form pieces of diamond in total. Cutters, with the help of computers, can now create ultramodern diamond shapes divided into almost 100 parts.
The consequence of such a complex cut is a very shiny precious stone usually worth up to several thousand dollars. Its cut emphasizes the fire and brilliance better than any type of a diamond shape. Losses that occur during cut processing remove about 50% of the valuable material, which also contributes to the cost of a Brilliant diamond. This problem is also the greatest deficiency of a Round diamond. These diamonds are mounted on the wedding bands as usual and as on other various jewelry pieces, but rarely embedded in metal to accent the brightness of the shape. Brilliants are most frequently seen as engagement rings, channel settings and expensive earrings. The popularity of the ring and diamond combination represents eternity and brilliance. It brought Rounds to top sales in the world in a comparatively short time. Jewelry blended with gemstones or earrings that can be worn for everyday wear are a good example of a Round brilliant diamond shapes. It is oftentimes placed on a jour or the prongs that distance a stone from the ring and thus highlight the diamond by uncovering the pavilion. The beautiful look of a loose diamond is caused by the geometric accuracy of the shape. It's highly recommended to follow the advices about choosing a diamond with at least Slightly Imperfect color grade. A Round diamond shape is definitely worth the buy.
