Before we know what a special-shaped diamond is, we should know the most common diamond shape - the standard round diamond type. This type has a total of 57~58 facet, including the countertop, upper waist surface ( kite surface), star surface, lower waist surface, and the main face of the pavilion (some to prevent the diamond bottom tip from being damaged and grinding out the bottom surface). Fancy Shape diamond, compared with traditional round diamonds, refers to diamonds that are cut in a special shape and maximizes the use of diamond embryos. Generally speaking, they are not round diamonds, but shaped diamonds.
The special diamond originated from ancient Greek mythology. The triangular diamond set on the Prometheus dagger gave him the courage to bring the fire to the world. The heart-shaped diamond on the tip of Cupid's arrow can make men and women bathe in love. The oval diamond inlaid on the Trident of Neptune Boston makes him invincible... In the current diamond market, special-shaped diamonds account for one-third of the market.
Although round diamonds are recognized as the best expression of the beauty of diamonds, special-shaped diamonds are better in terms of appearance and cutting technology. Compared with round diamonds, special-shaped diamonds have stricter requirements for cutting, and their unique diamond shapes have quickly become popular in the global fashion field. The cutting skills of special-shaped diamonds are much more difficult than round diamonds, and the cutting tools and cutting are not much time required. Among the masters who are proficient in diamond cutting skills, only a considerable number of them have mastered the method of cutting special-shaped diamonds. Generally speaking, "a master who can cut special-shaped diamonds will definitely cut round diamonds, but a master who can cut round diamonds will not necessarily cut special-shaped diamonds". And most of the world-famous diamonds are shaped diamonds. The world's largest coloured diamond is a pear-shaped diamond weighing 407.48 carat, which was sold for $12.5 million at the 1988 auction.
Types and cutting of shaped drills:
Initially, if the irregular diamond raw stone is cut into a circle, the loss rate is too high. Therefore, the craftsman cut it into various shapes according to the situation of the raw stone. However, later, the colourful shapes and rich personality characteristics of special-shaped diamonds have made them deliberately pursue diamond shapes. Coupled with the progress of cutting technology, special-shaped diamonds are gradually loved by most people as round diamonds. The carat weight of the shaped diamond can be retained by 55%-60% after cutting and grinding, while the loss rate of the round diamond is as high as 47% when cutting and grinding the raw stone, and only 53% are left after cutting and grinding the brightest diamond. Assuming that the same raw stone is cut into a round diamond is 0.8 carats, then the size of the pad may be 1 carat, which also means that the diamond is finished of the same size. The cutting and grinding cost of special-shaped drills is lower than that of round drills. For a special-shaped diamond, what is important is not its cutting ratio, but its symmetry. Therefore, when choosing a special-shaped diamond, it mainly depends on the symmetry of the diamond.
In addition to meeting the aesthetic needs of different people, special-shaped diamonds can also use their own shape to avoid defects in the original stone.
