The following is a brief introduction to friends why diamond cutting is so important . In diamond 4C which is important, diamond 4C sorting, we introduce cutting is the most important factor affecting quality outside the weight, select diamond first consider it The cut, why is it so important?
The most fascinating thing about a diamond is its rare, hard, shimmering, colorful light, and it can show such a beautiful light, largely determined by his cut. When the diamond is exposed to light, each angle, every The facet affects the total amount of light reflected back into the human eye; therefore, the radiance of the diamond is entirely determined by the diamond's cutting effect. In the 4C (color grade, clarity grade, carat weight and cut grade) that determines the value of the diamond, the cut grade is the most difficult to assess and is the only part of the diamond cutter that can directly affect the grade.
In view of the many variables and possibilities that need to be considered when cutting diamonds, diamond cutters have a variety of cutting options; whether it is manual cutting or machine cutting, choosing different cutting methods will give the quality and value of the diamond. The degree of beauty presents a completely different look; this is especially true for standard round brilliant cut diamonds. Although each facet of a diamond has an effect on the appearance of the diamond, the overall appearance of the diamond is primarily determined by a combination of factors. Therefore, for round brilliant cut diamonds, GIA will consider the ratio and interaction between the facets, rather than a single ratio.
GIA's rating for diamond cuts takes into account the design, process, relative weight-to-diameter ratio, waist thickness (impact robustness), symmetry of faceted alignment, and the quality of the finish of each facet. The dazzling brilliance of diamonds comes from three optical effects: brightness (sometimes called light), fire and sparkle.
Brightness refers to white light that is reflected from the inside and outside of the diamond.
Fire color refers to the white light being analyzed into a colorful spectral color.
Flash refers to the flashing of the light seen and the dark and dark areas of the diamond as the diamond, light source, or observer moves.
The diamond cutter's cutting decision will affect the above three optical effects, so the cut grade together with the color grade, the clarity grade, and the carat weight determine the final value of the diamond, so we recommend that the diamond be considered first. .
