In the diamond kingdom, sparkle is the capital to show your worth. Cutting is the power behind its shine, is the magic weapon that human beings give the rough rough stone bright light. Among the 4C's of diamonds, only the CUT is given by humans. It can be said that this only artificial C determines the ultimate value of the diamond. The perfect cutting process has naturally become the focus of many jewelry brands, and the "cutting competition" of domestic jewelry brands has been on the road.

Who made the stone shine with fire

The diamond with infinite brilliance is very inconspicuous before it is cut, which is commonly known as rough stone in the industry.

Shi Kun, chief designer of Diamond Bird, told from a professional point of view how the perfect cutting makes an inconspicuous "small stone" shine brightly.

The rough stone is not shiny, the permeability is not good, and it is very inconspicuous in the small stones of various colors. Once there was a little story, the world's first diamond was inadvertently kicked by a person passing by the beach just found, the "implicit" of the rough drill can be seen.

If the excavation and mining of diamonds is regarded as the first life given by human beings, then from the rough rough stone to the glittering diamond jewelry on the counter, the diamond has undergone a gorgeous transformation from the "infant period" when it was born to the "beautiful girl". This is all thanks to the precise calculation and determination of excellent cutting masters, and with the help of a high-precision computer cutting machine to give the diamond 57-58 facets, thus bringing the spectral aesthetics to the extreme.

At present, the commonly used rating methods in the world range from high to low, giving diamonds EXCELLENT, VERYGOOD, GOOD, FAIR and POOR ratings.

When the diamond is still a rough diamond, computer measurements calculate the cut ratio that best avoids internal impurities while retaining the maximum carats. It can be said that this first knife determines the future value of diamonds; Then through the mutual grinding of diamonds and diamonds, as well as the subsequent manual polishing, and finally show a crystal clear beautiful diamond.

In fact, under normal circumstances, the "diamond cutting" is a general term, which is related to whether the diamond flashes or not, and there are three evaluation criteria: CUT, SYMMETRY and POLISH, which are applicable to the rating division of the cut; If all three are EXCELLENT, also known as 3EX, then the fire color of the diamond is undoubtedly perfect.

China's top jewelers compete

According to data from the diamond distribution department of global mining giant De Beers, the demand for diamonds in China is slowing down. The latest figures from CLSA and China's National Bureau of Statistics show that jewellery sales in the first quarter of this year rose 20 per cent from a year earlier, compared with 59 per cent last year. Why will the jewelry market decline in performance this year?

It is reported that many consumers have simply come out of the understanding that big is good, the 4C standard refers to the carat weight of diamonds (CARATWEIGHT), CLARITY (CLARITY), color (COLOUR), CUT (CUT), these standards are more and more attention by consumers. The era of diamond consumption is slowly ending, and high-quality diamonds are gradually favored by consumers and have begun to be active in the jewelry market.

For how to create high-quality diamonds, most domestic jewelry brands choose to hold hands with internationally renowned diamond suppliers, so as to get the perfect cut diamond. For example, Chow Sang Sang's InfiniLove All-love diamond brand is made of high-quality diamonds cut by professional cutting technicians in Antwerp, Belgium, with extremely rigorous and accurate turning skills, and its turning is the highest level of diamonds in the world; The Estrella diamond was jointly developed by TSL and RosyBlue, the world's leading diamond manufacturer. Gold Supreme Jewelry and Crissut cooperate to launch the wedding diamond jewelry series, the first introduction to the mainland market.

In addition, cooperating with international top jewelry suppliers to obtain its patent is also a future development direction for domestic jewelers. For example, the Belgian top diamond cutting process blue flame diamond, which was introduced to the country by Tongling Jewelry in 2009, has recently obtained its exclusive cutting patent, which is the first time that a domestic jewelry brand has obtained an international top diamond cutting process patent. Perhaps in the near future, China's diamond cutting technology will also lead the trend of the world.

Diamond cutting procedure

Marking (marking) is the first step in diamond cutting, marking the surface of the rough stone that has been tested. Craftsmen need to carefully observe the structure of the rough stone with tools such as magnifying glasses, and sometimes it takes months to determine how to mark the rough stone. Because the first cut of a diamond determines the final value of a diamond.

The next step is to divide the rough stone, which involves a cutting and sawing process, through which the "beauty" of the diamond is revealed.

Finally, there is the flapping and polishing process, when the cast iron disc coated with diamond powder and lubricating oil is ground out all the flapping faces (facets), and the diamond finally gives off a dazzling glow.
