As the name suggests, shape (round, princess, pear, etc.) refers to a diamond's form. It is mainly viewed from above the diamond. The cut of the diamond refers to both, the diamond’s shape as well as how good the diamond is cut for proportion and finish. In diamond grading both of these factors are the only ones that are influenced by humans.
THE FOUR C’S of a DIAMOND
This term most people recognize when considering a diamond’s value. However, this is just one component that suggests value. Generally with all facts under consideration one would assign a greater value to a larger diamond when considering the 4 C’s. A diamond weight considers metric carats according to the GIA. Diamonds are divided like one percent into a hundred, where 50 points is 0.50 carats. It is important to remember that two diamonds of equal carat size can have very different values when considering the other value components.
Almost every diamond has some sort of imperfection even if it is very small. Those diamonds that have very few or no imperfections at all receive the highest grading. The clarity of a diamond suggests the absence external blemishes or internal exclusions. Because diamonds form deep within the earth’s core most usually have these unique marks referred to as inclusions which are internal, as well as blemishes which are external. Those diamonds which have very few of these marks are rare and are assigned a higher monetary value. The rarest case being a flawless diamond and most consumers and jewelers will never see one.
One of the main grading agencies is GIA and their Clarity Scale contains 11 different grades with VS and SI being the most readily available. In order to assign these grades the reporting agency considers the color or relief, size and nature, position, and the amount of clarity characteristics which are viewed under a 10x magnification.
There is no doubt that the most attractive feature of a diamond is its cut. The three main attributes of a diamond’s cut are its brightness (the maximum light reflected), its fire (the dispersing of light with the different colors found in the spectrum), and the scintillation (the sparkle as a diamond moves).
A thorough comprehension of the diamond’s cut starts with the shape of a diamond, with round being the most popular. The other seven major shapes are known as fancy cuts which include cuts such as the marquise, oval, pear, and emerald. Other modern shapes becoming popular are hearts and triangles, and a variety of new styles which are developing. Put more plainly, the better the diamond’s cut, the more it will sparkle.
When considering the diamond’s cut as a value component, the GIA considers the diamond’s symmetry, proportions, and its polish. In an example provided by the GIA one can look at the side of the standard round brilliant. The primary factors are the girdle, crown, and the pavilion going from top to bottom. A diamond with a round brilliant cut will have 57 or 58 facets, with the 58th being a small flat facet located on the pavilion, also known as the culet. The flat facet on the top is what is known as the diamond’s table. When considering the proportions of a diamond you would refer to the relation between the size of the table, pavilion depth, and crown angle. There are many proportion combinations which affect the synchronicity of a stone with light.
In 2005 the GIA unveiled a grading system for a diamond’s cut which consisted of a standard round brilliant in the D to Z color range and an overall grade for the diamond’s cut ranging from poor to excellent.
The color of a diamond refers to what you can actually see. The color value component considers how close they approach colorless; in other words, the less amount of color the more value. The most common range runs from no color to slightly yellow or brown. The exception in this component is for diamonds that are outside of this range (see diamond colors).
