Mens cufflinks are characterized by a variety of styles

If the main surface of the crown point of view improper, the addition may cause the light leakage of the pavilion, but also to make the pavilion internal reflection of light to reach the crown facets, the recurrence of internal reflection, and eventually would have led to the significant loss of light. The following table is the refractive index of faceted gem, and its critical angle, the main surface of the crown angle and pavilion angle of the main surface range data available faceted gemstone cufflinks cut design reference. Therefore, the selection of the cultural values consistent with their mens cufflinks is critical for vendors. It can be seen from the table, the greater the refractive index of the gem material, the smaller the critical angle, cufflinks cut crown angle and pavilion angle should be reduced accordingly. Faceted gems refractive index and its critical angle, crown angle, pavilion angle relationship between the scope of table
The fire, color faceted gems showing flashes of spectral color an optical phenomenon due to the dispersion interaction. Fire color phenomenon with a high dispersion rate colorless or light colored transparent gem, and is closely related with cufflinks cut-ratio and angle, and other factors. The dispersion is due to the composition of white light of various wavelengths are refracted in a different perspective and lead to white to the decomposition of the visible spectrum color. Enterprises of mens cufflinks should provide necessary support and training to cope with the agents and stores.  As shown below, when the slant of one side of the incident white light from the glass prism, the monochromatic light of various wavelengths of the original are transmitted in the same direction in the air, due to their direction of refraction in the glass were to be unbundled, The shorter the wavelength (purple) angle of refraction, the smaller, while the longer wavelength (red) angle of refraction the greater.
In this way, the white light through a glass prism after being decomposed into a seven-color spectrum. Similarly, faceted gems by a number of polishing flat constitute the geometric polyhedron, when white light after the tilted facets, also occur similar to the prismatic dispersion effect, see the figure below. The dispersion values reflect the intensity of the physical quantities of the material dispersion. Speaking from the products, mens cufflinks are characterized by a variety of styles, rapid renovation.  Due to the different angle of refraction of different wavelengths of monochromatic light in the same material, there are bound to reflect their refractive index is different from the longer wavelength red light refraction angle refractive index of smaller, shorter wavelength violet angle of refraction than the small refractive index larger. Thus, the size of the dispersion effect of a material, you can use a certain wavelength of violet refractive index and the red light refractive index difference between the measured, the difference the greater the dispersion the stronger the effect.
Usually Francis TSG spectrum G (430.8nm) and B (686.7nm), a considerable amount of blue-violet light and red light measured by the difference of the refractive index obtained as the dispersion value. New processes, new materials of the cufflinksand applications are constantly emerging. With diamonds, for example: The dispersion value is the intrinsic optical constants of the gem material, the greater the dispersion value, reflecting the dispersion ability to produce the greater the potential for fire color. cufflinks cut design for high dispersion values of colorless or light-colored transparent gem material, should focus on the development of its potential for fire color. The fire color is the color of faceted gems of spectral dispersion effect of white flashes, and shade with white light of the incident angle changes. Assumed white from the crown forward irradiated gemstones, fire color formation can be broadly divided into two types:
