Diamond cut depth resolution

Diamond cut often is easy to ignore the problem, only in 4 c diamond cutters is the only man-made factors can change. And many appraiser who also believe cut is the most important factors that affect the value of diamond, even a diamond with the most perfect color and clarity, cut not ideal also can make the diamond appears bleak. Diamond cut - its roundness, depth, width and carved the uniformity will influence the diamond brilliance. Diameter: measuring the width of the diamond at the waist. Desktop: the biggest diamond facets. Crown: the upper half of the diamond, flange extends to the desktop from the waist. The most wide waist: diamond ring parts. Bottom: the lower part of the diamond, extend from edge of the waist to bottom tip. The bottom of the bottom tip: gem facets. Often popular is invisible to the naked eye bottom tip, from 'small' ( 小) To 'no' ( 没有一个) 。 Depth: the height of the gem, from the desktop to the bottom tip of the distance. Ideal ( Ideal） The ideal proportion of diamond, when light enters inside diamond can refracting surface to another moment by moment, finally will be completely out of the diamond positive refraction of light, and let the diamonds glints, bright light, flashing attaining the state of the perfect acme. Too shallow, 浅) Diamond proportion too shallow, because the Angle of the diamond crown and booth is too narrow and too shallow, lead to light into the diamond to refract all light from the front of the diamond, most of the light from the bottom of the diamond light-leaking, lead to the phenomenon of 'fish eye'. Too deep, 深) Proportion too deep diamond, as a result of the diamond crown and pavilion Angle is too big, too deep, causing light into the diamond to refract all light from the front of the diamond, most of the shine by the side of the diamond light-leaking, lead to the phenomenon of 'pin'. The proportion of diamonds, particularly in depth and the waist diameter ratio, and the proportion of the waist diameter and the diameter of the desktop. These two factors will determine how the light inside the diamond surface reflection and refraction, determines the light with the light of the diamond. Cut is the only man-made factors can change polishing and symmetry is two important assessment in the process of diamond cutting, polishing level represents a diamond surface carved surface state, all levels including diamond proportion and symmetry precision, balance, and the accuracy of the drill stone carving face should be. One of the most perfect polishing can release the light and the light. While good symmetry can make diamond light, the light and flash to achieve perfect balance. Polishing and symmetry level will be clearly marked in GIA identification certificate. GIA cut standard & bull; The total depth & bull; Polishing/symmetry & bull; Bottom tip size & bull; No actual Turner level & bull; Desktop percentage & bull; The waist width & bull; Diameter measuring the most perfect diamond, can consult GIA level excellent polishing and symmetry ( 例) Very good ( VG） Or good ( G） Diamond grade, try to avoid have fair ( 公平) Or poor ( 可怜的) Grade of diamond polishing and symmetry, because of its proportion or carved the asymmetry will seriously affect the direction of the light within the diamond, affecting the light of the diamond and the light.
