The cut of the diamond is the most crucial aspect that goes a long way in determining the dazzle and of the diamond. This is one trait that the diamond maker can control and it makes a day and night difference, in the final result of the diamond. Contrary to popular belief, the cut of the diamond is not the shape of the diamond such as round, oval, heart, and so on. It refers to the proportions of the diamonds, the symmetry, the angle, and the polish. Diamond cuts have three primary effects on its appearance and these are:
- Brilliance: that refers to the brightness of the light that gets reflected and refracted.
- Fire: that refers to the dispersion of the light when it gets struck by a few flashes of visible color.
- Scintillation: The flashes of dark and light, or the sparkle when the diamond is moved about areas of varying light intensities.
When a diamond cutter begins his craft, he must find the perfect balance between the optimal cut and the maximum yield. The maximum yield is the retention of the maximum carat weight; the more you cut off, the less of the diamond you are left with. The better the optimal cut, the better you can bring forward the true exuberance and beauty of the cut diamond ring. Some customers prefer to go for a larger diamond with a fair-cut, rather than a smaller well-cut diamond. Understanding the customers’ requirements is the mark of a true diamond cutter.
Diamond depth is a factor that determines the cut of the diamond. The depth of a diamond is nothing more than the height of the diamond (in millimeters) measured from the bottom tip or the culet, all the way up to the table of the flat, top surface. On most grading reports there are two forms of this diamond depth, with one being the diamond depth in mm, and the other being the diamond depth percentage; the depth and width relation.
When light enters into the diamond, the depth of the diamond determines how much of an extent the light goes into the diamond, until it is reflected in the eyes of the observer. If the depth is too low, or excessively shallow then the light escapes from the bottom. If the diamond depth is too deep, then the light escapes through the bottom after causing refraction.
Too much or too little of the diamond depth and the true beauty of the real diamond ring stays hidden and unutilized.
