diamonds
1st carat
The carat refers to the weight of a diamond. This unit of weight and the term carat are derived from a completely natural unit of measurement: the seeds of the carob tree, because diamonds were actually weighed using these seeds in the past.
Today, one carat corresponds to exactly 0.20 grams of weight. One carat is divided into 100 points. A diamond with 50 points therefore weighs half a carat (0.50 ct). However, the carat weight alone does not determine the value of a diamond. Two diamonds with the same carat number can have different values, as clarity, color and cut also play an important role.

2. Colour
When it comes to evaluating the color of a diamond, it is basically a matter of assessing how close it is to being "colorless." The more colorless and white a diamond looks, the more valuable it is. The scale ranges from D (colorless and particularly rare) to Z (tinted).
At the same time, nature has also created diamonds that are characterized by a particularly strong and pure color. These are the rare fancy diamonds, which are also particularly valuable.

3. Clarity
Flawless diamonds are an absolute rarity. Most diamonds have tiny inclusions, which are often referred to as nature's individual fingerprint.
The clarity of a diamond can be determined by how many inclusions or impurities it has. The purer and higher quality the diamond, the fewer inclusions it has. Inclusions up to and including clarity grade si are usually not visible to the naked eye.

4th cut
In contrast to the other evaluation criteria, which are determined by nature, the cut is in the hands of man. Only a perfect cut can ignite the fascinating fire of the diamond.
The proportions and arrangement are important so that the incident light is refracted and reflected at the optimal angle. If the cut is too sharp or too flat, the light beam fizzles out. Only a diamond with the optimal cut can unfold its magical glow and achieve the desired total reflection.
5. Confidence
Trust is the key word when it comes to diamonds. As the evaluation criteria described above show, not all diamonds are created equal and only the highest quality standards guarantee the highest brilliance.
The fifth C, which stands for trust, also requires that the chain of origin of the diamonds is conflict-free and transparent. Only diamonds from trustworthy sources are mined, processed and traded under socially, ecologically and ethically acceptable conditions. This is why NÓIR only uses diamonds from certified sources
