What to know before buying a jewel with diamonds?

Earlier I talked about the symbolic and romantic part of the diamond, but today I thought about changing the chip and talking about the practical part of what you should know before buying a diamond in a jewelry store. Because the diamond apart from being something decorative with a high symbolic value has another very important value which is the investment value. Therefore I am going to explain to you in the following lines what you should know before buying a diamond.

The four C’s Before buying a diamond, the characteristics that influence its quality, and consequently its price, must be taken into account. To know this, four characteristics that determine the quality of the diamond must be taken into account. They are called “4C’s” and are: Color, Clarity (purity), Carat (weight or carat) and Cut (size).

Colour The color of a diamond greatly influences its beauty and price. The more colorless, the better quality. The color scale most used today is that of the American GIA gemological laboratory, which is the one used in most jewelers. This scale orders the color of diamonds from the letter D (colorless) to Z (yellow or brown). At this point, colored diamonds must be discarded starting from the letter J, since a yellowish tone begins to be seen in them.

Purity Diamonds are formed over thousands of years under enormous pressure and temperature. This process leaves inclusions or small internal imperfections in diamonds that determine their purity in the diamond. The purer a diamond, the more light it receives and reflects, producing a greater amount of brilliance than lower-clarity diamonds. The degree of purity of a diamond is determined according to the number, size and position of its external marks and inclusions, using a 10x magnification (10X) magnifying glass. The most widely used purity scale, from the GIA gemological laboratory, is divided into 11 grades ranging from the highest grade of purity FL (or Flawless) to grade I, also known as Piqué (chopped in French). At this point, what must be discarded are the Piqués, since they can be seen with the naked eye. For the rest of purities you will need the magnifying glass if you want to see something.

Weight The weight of a diamond is measured in carats (1 qt = 0.20 grams), and logically the larger, the more valuable the diamond is. The problem is that the price increases faster than the size. Thus the price of a one-carat diamond is not twice that of a half-carat diamond but five times more expensive. At this point it is clear: the bigger the better.

Size Although there are many possible sizes, the most common to get the most out of diamonds is the brilliant cut (the round of a lifetime). If the cut of the diamond is not too good, part of the light is not reflected and it loses part of its attractiveness. In principle, the brilliant cut is the most demanded, although it is a bit of a matter of taste. In our German jewelry stores, for example, we sell princess sizes very well, which, being also very showy, are more original. Whichever size you choose, you must discard the diamonds that in their certificate say “bad” cut.

In summary The price is a ratio of the four “C”, so if what you want is to buy a beautiful and apparent diamond, you have to prioritize color and size over purity, which is not perceived with the naked eye. A color between F and H will be a good choice, a purity of at least VS2, and the size… Well, the bigger the better, of course! And finally the most important advice: Look for a trusted jeweler and if possible buy certified pieces, because even if you have read the entire article, you will not be able to distinguish the qualities by yourself.
