What are the types of diamonds?
Diamond jewellery shines, but a diamond has experienced many hardships from the rough stone that has been mined to the gleaming diamond. The diamond deserves such a high price and is worthy of being called the king of gems. So, what are the types of diamonds? Pointed type The pointcut is the earliest polished shape of a diamond and is limited to smoothing the eight faces of the octahedron. Since the octahedral surface itself cannot be polished, the polished surface has a small angle of intersection with the octahedral surface. The purpose of polishing is to improve symmetry and obtain transparent diamonds. Table shape The table shape simply rubs off a corner of the octahedron, which forms the shape of the four natural sloping ribs of the crown, which in turn evolves into a stepped facet. Rose flower type The rosebud type is a flat bottom, a vaulted dome type, and the top is covered by a small triangular facet. This type of flaw has a small mass loss and a more beautiful appearance. It is suitable for flat crystals made of rosettes. The disadvantage is that the fire color is insufficient. . Despite this, the rose enamel type has been popular for decades, and some of the world's most famous diamonds are such scorpions. Single polyhedron The single multi-faceted single cut is an over-type of the shape of the table-shaped å‘-shaped to the multi-faceted , type, which is similar to the modern eight-cut shape, but the appearance is not circular. It is a slanted table shape with four corners worn away. Double polyhedron The double-folded doublecut is a single-sided scorpion type that many people think is the result of the bishop's advocacy by Mazarin, so it is also called the Mazarin. It has a cushion-like shape with a total of 34 facets, 16 of which are in the crown and 16 in the pavilion, plus 1 countertop and 1 underside. In addition, there are two variants of the double-faceted enamel type: the British star-shaped enamel type and the British square ç¢ type, the star-shaped ç¢ type has a distinct horn-like appearance, the square ç¢ type is a cushion-like shape, and in addition, the pavilion of the pavilion is also different. Triple polyhedron It is believed that the triple-cut triplecut was designed by Venice's diamond polishing craftsman Vincen-zio Peruzzi, who increased the number of small faces to 58, including the countertop and the underside. This increases the brightness and fire of the diamond. But the form is still irregular. Classical European style The classical European enamel type is the result of further improvement of the above-mentioned ç¢ type, the size and angle of the facet are more uniform and symmetrical, and the waist rib has a more round shape. This type of ç¢ is closer to the modern round multi-faceted ç¢ shape in shape and style. Fancy type Fancycut refers to any modern diamond type that is not round and multi-faceted. It is estimated that only about 10% to 20% of rough diamonds are processed into this type. This is mainly due to the fact that the final polished form depends to a large extent on the original rough form. Another factor is that the fancy type is more expensive to produce, only a few experienced artisans can make it, and it is a time-consuming job, so manufacturers are often reluctant to produce this type. There are many styles of fancy enamel, which are basically divided into two groups according to their respective characteristics: each group requires different crafts and different rough diamonds. The first group is a deformed round multi-faceted ç¢ type, which evolved from a circular multi-faceted ç¢ type. The facet distribution of this type of scorpion is similar to that of a round facet, except that the contour of the waist is different. Oval, olive, pear and heart are common; the second group is stepped ç¢, common square and emerald. In addition, the stepped shape has many different forms, such as wedge, diamond, triangle, trapezoid and kite.
