The issue of the manufacturers is how to create such a cufflinks culture

Compared to the gem's surface reflected light (gloss) is the brightness of the contribution is of course important, but instead of reflected light role, the role of internal reflection faceted gem on brightness far better than the surface reflection effect, corundum, for example, The corundum refractive index N of about 1.76 into the above formula: The corundum surface reflectivity R = 0.76. In other words, only 7.6% of incident light reflected at the surface, if the remaining 92.4% of the incident light into the corundum faceted gem internal, and then shot through the internal reflection effect from the front brightness of the gem will greatly improve the . Thus, the internal reflection effect is real potential to improve the brightness of faceted gems. Of course, the issue of the manufacturers is how to create such a cufflinks culture.
As shown below, only managed to refraction or direct light into the gemstone body to reach the various facets of the pavilion angle of incidence greater than the total reflection critical angle, and finally reflected to the crown facets of the angle of incidence is less than the critical angle , so as to make the light from the gem positive (crown) injection. The gem of the refractive index is larger, the smaller the critical angle. Different mens cufflinks will represent corresponding cultural groups. Due to the intrinsic optical constants of refractive index and critical angle are precious stones, can not change, the only way to change the light into the gemstone body angle of incidence of the various facets. Thus, according to the faceted gems in the gem of the refractive index and critical angle size to a reasonable design cufflinks cut ratio and angle, is the only way to enhance the gem brightness.
Faceted perspective of the brightness of the impact on the brightness of the angle of the facets is very obvious, especially the angle of the pavilion main surface and crown surface angle. If these angles are poorly designed, too large or too small will lead to the thickness of the faceted gem is too large or too small, so that light can not be a shot from the front, but the loss of the pavilion, resulting in the weakening of the gem the appearance of brightness. It is important for the manufacturers to note the selection of the cufflinks. The impact of the main facets of angle of reflection light generated within the appropriate proportion and angle, can produce a better internal reflection of light; the pavilion angle is too large, resulting in the pavilion is too deep and leaky; pavilion angle is too small, resulting in the pavilion is too shallow and leaky; The crown angle is too large, resulting in a total reflection of the crown and pavilion leaked
Cufflinks cut-faceted perspective to produce reflected light affect several circumstances: Only appropriate cufflinks cut proportions and angles in order to allow light to produce total internal reflection effect in the pavilion, while the shot from the crown, showing good internal reflection light; If the main side of the pavilion angle is too large will cause the ratio of the pavilion is too deep, the light refraction occurs in the pavilion engraved surface, leakage from the pavilion side of the body (called the second light leakage), resulting in loss of light, brightness is weak; The main side of the pavilion angle is too small, the ratio will result in the pavilion is too shallow, so that the light refraction in the pavilion engraved surface, penetration leakage from the back of the pavilion (called the first light leakage), resulting in brightness is not good. Once the cufflinks are introduced, it is difficult to be changed.
