Buying a diamond remains an investment requiring some knowledge.
As you know, there are several qualities of diamonds. Whatever quality you look for, it is necessary to ensure its precise value.
For this, four characteristics are to be considered, called the 4Cs. Here they are :

1- Weight (Carat)

The weight of a diamond is measured in carats indeed. Keep in mind first of all that 1 carat = 0.20 grams. Some diamond professionals also speak in points, knowing that 1 carat = 100 points.
However, a diamond bigger than another does not give it more beauty. According to its proportion and the way it is cut, a small diamond will sparkle more than another diamond with twice its size.

2- Size (Cut)

This is the most important feature to consider when buying your diamond. It is essential not to confuse the diamond shape (round, princess, marquise, oval, pear, emerald, radiant or heart) and the proportion of diamond, that is to say how it is cut.
A perfectly cut diamond will have by definition, perfect proportions. In other words, each facet of the diamond must be positioned precisely so that its symmetry allows light passage equally. This will then give it maximum shine and brilliance.

3- Color

The color (stain) of the diamond, is the only characteristic determined by nature and not by humans. In the middle of the diamond, its color is graded from D to J, D being the rarest.
In other words, the more colorless a diamond is, the more rare and valuable.

4- Purity (Clarity)

Each stone is unique. When each stone takes shape in earth depths, microscopic natural and plant traces take shape inside the diamond. These traces are called inclusions. The fewer inclusions inside your diamond, the more it will be clean (pure).


The certification guarantees

Every diamond is unique. Many are similar, with very similar qualities. However, only the certificate will give written evidence in due form of its specific characteristics. It is, somehow,your guarantee of quality.
This certificate provided by Capital Diamond for each transaction, will give you the precise characteristics of your diamond, the 4Cs: weight (carats), size (cut), color and purity (clarity).

Where the certification of a diamond comes from?

Many specialized laboratories worldwide are responsible for analyzing and certifying your diamonds. The best known are the Gemological Institute of America (GIA), the High Diamond Council (HRD) or the IGI laboratory.

However, it becomes obvious that these laboratories do not have the same rigorous analysis and certification. In order to provide full transparency and ensure the quality of our stones, Capital Diamond has chosen to entrust its certifications to the most reputable laboratories in the world: GIA, HRD, IGI, IGL.
