Our team of diamond experts can tell you all about the properties of diamonds and their value. The quality of a diamond is assessed on the basis of 4 aspects; Cut, Carat, Clarity & Color, or the 4C´s. Below is a detailed description of all 4 C’s.
The cut of a diamond is the most important element in choosing a diamond. The cut includes the diamond’s proportions and symmetry as well as the overall finish. The better the cut, the more brilliance the diamond will have as its facets come in contact with light. This characteristic is graded based on a five-point scale with “Excellent” representing the highest quality and “Poor” the lowest. Cut plays a very important role in determining a loose diamond’s quality and ultimate value.
Carats are the units of measurement used to weight diamonds. A diamond carat weighs 200 milligrams. Smaller dianonds are measured using the point system, with 100 points being equal to one carat. Generally speaking, diamond price tends to increase based on carat weight. This may vary, however, based on other characteristics. Larger diamonds typically are considered rarer and tend to fetch a higher price if the other characteristics included in the 4Cs represent quality. Keep in mind that two loose diamonds of the exact same carat weight can have two very different prices based on other factors related to the 4Cs.
Considering the extreme heat and pressure required for natural diamonds to form, it is quite common for individual gems to display tiny, internal imperfections. Almost all diamonds, in fact, have some internal inclusions or external blemishes. Most diamonds have flaws that cannot be seen except through the use of 10x magnification. Tiny flaws that cannot be seen by the naked eye are not likely to affect splendor of the diamond. They can have an impact on quality and value though.
Clarity is rated on a scale that ranges from “flawless” to “included” with different grades representing the evidenced severity of inclusions and blemishes. The lowest-quality diamonds, for example, may have inclusions so severe they affect brilliance and transparency. Generally speaking, most diamonds with different clarity grades will look exactly the same to the naked eye, but will command differing quality rankings based on what is witnessed under magnification.
Diamonds are in several varieties from colorless to yellow. To determine the color, diamonds are compared with an already assessed set of stones, the color of which is different. The ranking goes from D (colorless) to Z (the yellowest), but a stone is seen as yellow from color K.
Diamonds can also have another color in addition to white (for example, yellow, blue, pink or orange). Depending on the intensity, these diamonds are called ‘fancy’. Fancy color diamonds are rarer than white diamonds. Especially when the color is intense, the value increases significantly.
