What is a diamond?

What is a diamond?

The diamond is a mineral composed of carbon. It is the hardest stone of all natural materials, elle can therefore only be scratched by another diamond. The word diamond is derived from the Greek "adamas" which means the hardest metal.

The diamond is considered the most precious stone, these small minerals formed at the same time as the Earth. If you wear a diamond on your finger, know that it is billions of years old. The diamond is probably the gemstone with the most meaning, it is also a highly sought after stone. So choosing a diamond for various reasons should be done meticulously.

Buying a diamond: an ethical and responsible approach

The popularity of diamonds has not always had good effects on people. We often talk about Blood diamonds which are war diamonds. In fact, these are diamonds that have been obtained and sold illegally by rebel groups to finance conflicts in war-torn regions, particularly in West Africa. Of course, these conflicts have led to many stories and tensions between certain countries. In order for this to disappear and for these "conflict zone" diamonds not to be able to penetrate the legitimate market, diamonds are controlled at every stage of supply: from extraction to retail sale.

These processes are called the Kimberley Process and Warranty Systems. The Kimberley Process is a system mandated by the UN. Over 99% of diamonds today are certified as coming from peaceful countries through the Kimberley Process. War diamonds now represent less than 1% of global production. When buying a diamond, it is important to check that it does not come from these conflict zones in order not to stem this movement.

The diamond market helps to transform people's lives around the world, particularly in Africa. Indeed, the revenues generated by diamonds contribute to the employment, education and health sectors (fight against AIDS).
At Celinni, we pride ourselves on respecting the Kimberley Process Charter. Thus, none of our diamonds come from conflict sources. Each of our diamonds follows the Kimberley Process.

One of the most important characteristics of a diamond is its size.

Why do the diamonds from the Celinni shine so much?

Why do the diamonds from the Celinni shine so much?

The size of the diamond is the only characteristic made by the hand of Man: either by a diamond dealer or by a lapidary (gem cutter).

The rough diamond is different from the diamond set on jewelry. Their sizes are usually made in Antwerp, Tel Aviv or Gujarat (India) by the Jain community. A diamond acts like a prism to light and brings out the colors of the rainbow. This quality is possible thanks to the size of the stone and its polishing. Even if a rough diamond already has this prism effect, when it is cut this quality stands out more.

The diamond is the hardest stone elle is 10 on the Mohs scale. Before cutting the stone, it is examined to know what its cleavage planes will be. This examination aims to determine how the lapidary will cut the stone to bring out the most beautiful.

Once the cleavage plans are made, the lapidary will draw a line marking the perimeter of these plans and a small groove is made with a kind of wood that carries a diamond at its end. Through this opening, a thin steel blade is introduced, a sharp blow is given and the stone is divided in two!

The diamond can be cut in different ways and therefore have different shapes. The most well-known and the one that best highlights the beauty of the diamond is the "brilliant" cut. Indeed, elle has been studied to have perfect proportions and give the most possible shine to the diamond. The "brilliant" cut transforms the rough stone into a true jewel of light, revealing 58 facets, regular and precisely defined in size on the surface of the diamond. You understand, this is when the magic happens.

Purity and color are two other characteristics of the diamond, they are more familiar. But the cutting proportions for a diamond are very important and often poorly understood. However, these are an essential quality factor. They directly condition the brilliance and the "fire" of the diamond. At identical color, a diamond with good proportions will be much more brilliant than a pure diamond incorrectly cut.

Since the appearance of the Tolkowsky cut (1919), diamond cutters have continually sought to optimize the brilliance of the diamond. Of all the diamond cuts, it is certainly the round brilliant shape that has been the most studied and is the most accomplished. Today, the proportions applied to this cut result directly from the understanding of the optical laws of the material and the mastery of the cutting and polishing technique.

Without any real knowledge of diamonds and their aspects, it is difficult not to make a mistake or even get fooled when you want to buy a diamond. One might think that the most important criterion for a diamond is its color when it would rather be its size. One might also think of buying a beautiful certified diamond when it is a Blood Diamond. At Celinni, our diamond dealers are trained and our diamonds undergo internal and external certifications. Which will prove their quality.

1) When buying a diamond, it is essential to look at it in daylight. If this is not possible, look at it under a cold light lamp.

2) There is a diamond planet called: 55 Cancri-e. Elle was spotted in 2011 by Franco-American scientists, elle carries billions of tons of diamonds at a

3) staggering speed around a star visible to the naked eye. It is a very hot rocky planet largely composed of diamond.


The origin of the word diamond: "adamas" initially designated the hardest metal, then any very hard material like magnetite for example.

The diamond dealer's advice

Choose a professional with a good reputation. Your sources should then be reliable. Refer to a recognized diamond dealer like Celinni.

  • If you are using a ring sizer and are hesitating between two finger sizes, we advise you to choose the larger of the two sizes.
  • A diamond is chosen by a stroke of heart, it must correspond to you, make you "vibrate" and you must feel "feelings" towards it. You look at it for the first time and you say to yourself "it's him, it's the right one" a bit like when you meet the love of your life. You can visualize it by microscope directly on your computer or in our jewelry stores.
