rose gold stud earrings Basic quality evaluation of rubies

(1) Color. The ruby ​​with the best color is calledpigeon’s blood red”, det er, the color is as red as the blood of a pigeon, with a bright red color. Selvfølgelig, true pigeon blood rubies are very rare. Rubies are the best in category A (“pigeon’s blood”), followed by category B (pigeon blood rose), category C (rose red) again, and category D (light rose red).

(2) Quality. The mass unit of rubies is the same as that of diamonds, which is carat (ct). Rubies of 1 ct are rare, and rubies larger than 5 ct are rare.

(3) Klarhed. Because rubies generally contain obvious inclusions, the clarity evaluation standard is low. Generelt, there is no visible inclusions and the quality is good. If it is visible to the naked eye but not very obvious, and it will not affect the firmness of the gemstone, it is also acceptable.

(4) Transparency. Ruby is not high in clarity, and Gan Qi’s transparency requirements are not high, and for star ruby, translucent or even opaque is better. As long as the clarity is not affected, jo højere gennemsigtighed, jo bedre.

(5) Cut work. Ruby is very particular about cutting, and its refractive index is lower than that of diamond. Derfor, if ruby ​​is to produce total internal reflection, the angle of the pavilion must be larger than that of diamond, which means that the pavilion must be deeper than diamond; The starlight effect must be cut into a curved surface. The arc height should be appropriate, too low the star line will blur, and too high will affect the appearance.

In short, the main evaluation of ruby ​​is: whether the color is pure (no unpopular colors or hue, such as the gray tone in ruby), whether the clarity is good (no or few blemishes, inclusions, ribbons, stripes, osv.), and whether the color is uniform , Whether the transparency is high, whether the processing ratio of each part is in compliance with the regulations, whether the polished surface is flat and smooth, whether the style is novel, whether the quality is above 0.3 ct (for ring noodles, use more than 0.3 ct, mindre end 0.3 ct can only be used for group Inlaid jewellery. Rubies exceeding 5 ct are rare and must be priced separately).
