Evaluating a diamond is both a trade and also a skill, it needs competence and know-how. Profesionals worldwide use a technique referred to as the 4C's.
Color, cut, clarity of diamonds in addition to carat is the only viable way of determining the actual diamond assessment. These 4 attributes play an independant role of one another yet all work in conjuction to arrive at the conclusive appraisal.
We are going to refer mainly to color, cut, clarity of diamonds since these 3 attributes are subject to graduations, whereas the final attribute "carat" is really a known attribute by virtue of the fact that the stone simply must be weighed to work out the outcome.
When referring to color, diamonds are graded in descending classification from whites being the most expensive to yellow colored stones being the lowest priced. In fact, diamonds come in all colors within the spectrum, but for commercial and trading purposes, the overall variety lies between white - yellow. Fancy tinted stones as in pink, red, blue and green are so rare that the cost is solely centered upon supply and demand.
Cut is simply separated into three sub-categories, these are:
The "shape" can be quite straight forward. Diamonds are cut into a range of shapes to be able to get the most out of the weight. The most typical shape is a round brilliant, whereas all other designs are called fancy shapes. These include the pear, oval, marquise, heart, ascher, cushion, radiant, princess and emerald. Round brilliants are costlier than fancies merely as a result of demand and supply.
The "symmetry" is the actual proportions of that stone. Imagine this like accuracy whereby angles and percentages come into play. This grading is very strict since some misalignments will deter on the brightness and lustre within the stone.
The "finish" is the grading for the workmanship. Think of this as tidyness. A diamond cutter may be interpreted just as one artist as a consequence his quality of labor is therefore graded as the "finish".
Clarity refers back to the inclusions inside the stone. A number of are spotless while some contain a variety of flaws, like bubbles, cracks (known as gletzes), in addition to some black or white spots. The flaws are subsequently graded as per what number are occurant, their size, and in addition their position. The cleaner the stone, the higher the price.
Carat is the measurement of weight. As noted previously, it is already determined by means of weighing the stone, thus no graduation needed.
Color, cut, clarity of diamonds are therefore the three attributes graded in order to determine the appraisal.
