The diamond is the queen stone of jewelry not only for its value but for the specific characteristic of refracting light in many crystalline reflections and magical glows that only a diamond can give.

Diamond offers a wonderful collection of Comete, with a wide range of rings, earrings, bracelets, and necklaces. The items set with diamonds are accompanied by their own certificate of guarantees and authenticity in which all the characteristics of the diamond are illustrated.

All diamonds are rare, but some are rarer than others and therefore of greater value. To determine the characteristics and the value of a diamond it is necessary to know the ” 4 C ” Carat, Color, Clarity, Cut. The best combination of these four characteristics determines the greatest value of the diamond.

Carat Weight refers to the weight. The carat is often confused with the size even if it is actually a unit of weight. 
A carat can also be divided into 100 “points”. A diamond of 0.75 carats can also be referred to as a diamond of 75 points or ¾ of a carat.

A one-carat does not cost exactly twice as much as a half-carat diamond, as larger diamonds are rarer in nature, which places them at the top quality pyramid, a one-carat will cost much more than double that of a half-carat of the same color, clarity, and cut.

This parameter refers precisely to the color. 
The color range varies from ice white to warm white. Diamonds are classified according to a scale established by the Gemological Institute of America (GIA) which goes from D (colorless) to Z. The colors indicated in the table are only to show the differences in shades. The letter D refers to perfectly colorless stones, the rarest and most expensive. Below we have the color E (exceptional white), F (extra white +), G (extra white), H (white), IJ (slightly tinted white), KL (tinted white), MNOPRSZ (tinted). 

Purity is evaluated according to the number of inclusions present. Almost all have inclusions within them, sometimes referred to as “fingerprints of nature”. They are natural identifying features, such as minerals or fractures, which appear during the formation of the underground. They can be in the form of small crystals, clouds, or feathers, however normally not visible to the naked eye.

To see the inclusions, jewelers must use a magnifying glass that allows them to see a magnified 10 times so that they can better locate the inclusions. The location of inclusion can help determine the value. There are very few in nature that is completely free of imperfections and these are therefore extremely valuable.
Inclusions are rated on a scale of perfection, known as purity, established by the Gemological Institute of America (GIA). 

Some inclusions may be hidden by the setting and therefore have little effect on the beauty of the stone. An inclusion in the center or on the table could affect the scattering of light, thereby decreasing the brightness of the stone. The higher the clarity, the greater the brilliance, value, and rarity of the stone.

The cut is the only one of the 4Cs to be affected by the hand of man. Based on mathematical formulas, a well-cut will reflect the light internally from one facet to the other like in a mirror and then scatter it and reflect it through the crown and the table.

The cut can also refer to the shape, for example round, square, teardrop, heart. Since a round diamond is symmetrical and able to reflect practically all the light that enters it, this is the shape with the greatest brightness and follows specific guidelines regarding proportions.


Many people confuse the word “diamond” with the word “brilliant”. It is the precious stone of extreme value; the brilliant is a type of cut (the round cut) which due to its characteristics allows the best shine. So any stone, for example, zircon, can have a brilliant cut, but it has nothing to do with the diamond stone.


The value depends on its weight and quality, but not proportionally. The higher the capture the rarer the stone and therefore its value increases considerably. Two stones of equal weight can have two completely different values ​​if they do not have the same characteristics of purity, color, and cut. The most important deposits are found in India, Brazil, and South Africa. 

Diamond veins can also be found in the countries of the former Soviet Union. The largest diamonds found so far are the Cullinan (South Africa) of 3106 carats, President Vargas (Brazil) of 726.60 carats, the Grand Mogol (India) of 246 carats. All stones of inestimable value.


We can certainly consider the diamond the gem of gems, to keep its beauty and value unchanged over time, just a few tricks are enough. Periodically the jewels must be washed in warm water with a common degreasing detergent, washing with the aid of a brush with soft bristles. Rinse thoroughly, always using the toothbrush.

 It is a good idea to keep the jewels inside their containers. When this is not possible, it is advisable to keep them, avoiding rubbing between them. These simple treatments will keep your jewelry better over time. Small or large, a jewel is something that lasts over time, because happiness is in the memories.
