It marked the width of the diamond, as well as the edge of the diamonds. Standard round brilliant diamonds, waist edge, in fact, by 16 'hill' and 16 'valley', by connecting the upper facets and pavilion in the crown area of area in the second half of the facet to form. How much is the thickness of the waist? An average waist size thickness by optical device to mm for the unit of measurement, actually. To calculate the percentage, the average diameter of diamond you need to be divided by the average thickness, and the results will be multiplied by 100. GIA describe the thickness of the waist level has a very thin, very thin, thin, and is a bit thick, thick, very thick and very thick. If we look at the two extremes, we got two very different conclusions: when the belt is very, very thin, it is fragile, the diamonds can be easily damaged. On the contrary, very thick belt hidden carat weight, means that the same diamond carat, belt very thick diamond looks smaller from the front. It is important that the belt homogeneously fan, and 'the hills' and 'valleys' on the size and shape are rules, you can give it a good grade. How to increase quietly carat? Polishers can use known several kinds of technology, in order to get maximum diamond weight, these technologies is known as the brush stuck between grinding and grinding. Both basically include the upper facets and the second half of the facet towards kite facets or tilt pavilion department main facets, or make them leaning toward each other. In this way, can produce in a certain part of the waist edge thickness, thus can increase the total weight of the stone slightly. Usually, if the visual impact is less than GIA create a minimum threshold, so, we think it's influence on diamond and the overall classification is reasonable, therefore, it is a feasible technology. However, excessive levels of mining can significantly change and influence the appearance of the diamond, so it can be reduce the cut level.
