The properties that determine the quality of a diamond are size, color, purity, and carat weight. These characteristics are also referred to as “the four Cs” (4 Cs). So what are these 4 Cs, you may be asking? Well, if you want to find out just how diamonds are valued, then read on below!

Size

A good size is the one that manages to produce more brightness and sparkles, reflecting the maximum light. The best cut is achieved when the proportions between the different parts of the diamond are adequate, if these proportions are not good, the diamond will not shine the same, or it will look dull.

Although, undoubtedly, the best known is the brilliant size. It’s the way most people come to mind when they hear the word diamond.

If you intend to buy a diamond, demand a certificate, because if you do not, you can never know for sure if it is well carved or what value it has.

In the HRD and proper certificates, the proportions are indicated in the section of the same name according to three grades: VG (Very good), G (Good), UN (Unusual).

If the certificate is from the GIA, we cannot know directly if the proportions are good or not.

Color:

The best color is, without doubt, colorless. As this lack of color decreases, yellowish or brown shades begin to appear until the end of the series with clear yellow tones. The presence of color is mainly due to the presence of impurities and structural defects.

As the color tone is more yellowish the price of the diamond decreases, and therefore, also its value, although there are exceptions. Fantasy diamonds have a strong color (red, yellow, blue, green …) and are exceptional in rarity and price.

Diamond Purity

In the crystallization process of diamonds, nature leaves traces as inclusions that do not affect the beauty of the diamond. A diamond that lacks inclusions is of the highest quality.

It is understood by the purity of a diamond to internal perfection, including minerals, cracks and growth phenomena influence the purity and are jointly named inclusions. Diamonds that do not present any inclusion when viewed with a magnifying glass at ten magnifications are considered magnifying at the magnifying glass level. Defects that can be seen at higher magnification are not considered in the valuation of purity. You should consult with an expert on gems to determine the purity of a stone.

Carat

The diamond’s carat is a unit that is only used in gems, and that is equivalent to 200mg. In turn, each carat is divided into 100 points. Thus a diamond of 25 points is equivalent to 1/4 carat, and a diamond of 50 points is the same as one of half a carat.

The more carats, the more price. But since other factors such as color, purity, and size are also involved, it is possible that a small diamond is worth more than a larger one, since the quality of the small one may be better than that of the larger diamond.  There are diamonds of all colors the most frequent are yellowish tones. The rarest and colored in green, red, blue, purple, brown and yellow are the so-called fantasy colors Fancy Diamonds and reach value for fans. Only within reach of collectors.

Diamonds are classified according to their hue and are more precious the more white they are. But, for practical purposes, a diamond begins to be visible its yellowish hue when it is cataloged within the GIA scale in color I or higher. Therefore, diamonds cataloged from color H are colorless to the eye and of exquisite beauty.
