Brilliantschliff

The classic form of the diamond cut is the brilliant cut. It is used for numerous gemstones. Only the round shape can be called a brilliant cut for diamonds, if they are over 57 Facets. Its features are three-, four- and polygonal facets in the form of polished smooth and flat surfaces, which are arranged symmetrically around the gemstone. The crown ending with the tablet, forms the upper end of this diamond cut. The widest part of the diamond, the girdle tapers down to the pavilion. This carefully executed diamond cut creates perfect proportions, whereby the diamond exudes all its brilliance and fiery shine. The maximum has been reached, when the gem sparkles in the spectral colors of a rainbow. This diamond cut is very often used on diamond rings. Together with a prong setting made of white gold, it is almost perfect as an engagement ring.

anatomy

As already described, the gemstone with the classic brilliant cut consists of a crown, which is completed with a tablet. The widest part of the diamond, the girdle tapers downwards and merges with the pavilion. The numerous facets are arranged according to a fixed scheme. The so-called star facets are arranged around the table. Together with the board, these form the shape of a star. This is followed by eight diamond-shaped kite facets. Finally make up 16 Upper Gridle Facets the transition to the girdle. At the bottom they are linked 16 Lower Gridle Facets an, and the end of the pavilion form eight main facets. Often the lower tip of the gemstone with this diamond cut is replaced by a wider facet.

history

As already described, the brilliant cut was developed as a form of diamond cut over many centuries. The outcome was the natural octahedron shape of the diamonds. It took up into that 14. Century into, until technical possibilities for diamond cutting were available. Previously, only unprocessed rough diamonds were known. In the beginning, only the eight surfaces of the rough diamonds were polished, so that the gloss was increased here. These diamonds were then known as pointed stones. One 1500 the two tips of the gemstones were removed. This created a large tablet on the top of the diamond and a small culet on the underside. Towards the end of the 15. In the 19th century, it finally made it, to vary the square shape of the gemstones. This was an important step towards today's brilliant cut. Additional smooth surfaces were added. First the octagonal was created, Form designated as a simple good. In the further development, more and more finer and differentiated ones emerged, Diamonds designated as double and triple good.

Proportions

This diamond cut is characterized above all by its characteristic proportions. At the end of the 17. In the 19th century there were already gemstones 58 Facets. However, these were not yet arranged symmetrically and thus could not ignite the inner fire of a diamond. So that the spectral colors of the rainbow come to full development through the light irradiation, certain proportions and angles must be adhered to when cutting a diamond. The brilliant cut known to us today was created in the year 1910. After that, extensive research work was carried out, to find out the ideal proportions for such diamonds. The optical effects and the happy play of colors should come into their own. One result of the extensive research is 1919 developed the Tolkowsky diamond. In the USA it is still a well-known brand for a good diamond cut today. This is named by the scientist Marcel Tolkowsky. In Germany, on the other hand, the fine-cut diamond became the starting point for research work. 1949 Eppler calculated its proportions after extensive research. The brilliant cut diamond must neither be too flat nor too high. Otherwise its brilliance suffers. The facets must be arranged symmetrically and evenly. Care should be taken when buying, that the diamond cut was well done. After all, this is crucial for the effect of the diamond.

Hearts & Arrows

Hearts are a special form of brilliant cut & Arrow cut. With this diamond cut, there are eight point-symmetrical and outward-pointing arrows on the upper side of the gemstone, and eight point-symmetrical hearts can be seen on the lower side. So that this overall result is achieved, need exact angles- and length ratios are observed.

Heart-shaped diamonds

The heart-shaped diamond is truly unique. There is no better symbol for love. The cut is great for romantic ones, sensitive and sentimental women. Famous people like Andrea Hissom and Joan Collions have already worn heart-shaped diamonds.

Hearts Diamond & Arrow cut

The heart & Arrow's diamond is a product of chance. The Japanese Takanori Tamura noted in the 80s, that certain parameters in diamond cut create a pattern of arrows and hearts. Following this discovery, specialized laboratories were developed in Japan, who strictly adhered to the proportions laid down by Tolkowsky in the Diamond Design treatise. A lot of emphasis was placed on perfect symmetry and that for the Hearts & Arrow design laid out necessary proportions. For example, the facet of the table must be smaller than with the classic brilliant cut. The name Hearts & Arrows was 1988 patented by Klinsaku Yamashita. At the beginning of the 90s, the popularity of these gemstones was carried from Japan to the western world. So that the Hearts & Arrows pattern is clearly expressed, a Firescope is required. This is also known as the Cupid Cut Loupe. This is a special reflector developed by Kazumi Okuda in the 1970s. With its help, a kaleidoscopic pattern can be recognized, which shows the intensity and direction of the light reflected from the diamond. To the naked eye are the Hearts & Arrows not recognizable. Nevertheless, the precise cut is characterized by a fiery sparkle and a very high level of brilliance. It is a precious and rare form of diamond cut. Therefore, this diamond cut is not only available in small numbers, but also correspondingly expensive. The processing of a gemstone with this diamond cut takes approx. four times as long, such as an ordinary brilliant cut. The facets have to be set very precisely. Even the smallest deviations destroy the desired pattern. The weight loss is also comparatively very significant here.
