How to choose a diamond

The beauty, the rarity, and the value of a diamond depend on the combination of 4 parameters: color, cut, clarity and carats. If a diamond owns high values in all 4 parameters then it belongs to the rarest and most valuable of its family. It goes without saying there is no need to buy the most rare diamond to express your love.

Cut - A right cut brings more shine

danelian diamond cut

The cut is a very important component for a diamond as it does not only give its shape but also releases its brightness, shine and beauty. The right cut presupposes extensive knowledge, agility and talent from the polishing specialist. He must achieve with greatest precision the perfect geometric synthesis and arrangement of each of the 58 facets of a round diamond (the number of facets varies with the shape). And allow to the light to penetrate perfectly inside the diamond and reflect back with all its initial power. The value of a diamond can very easily be destroyed from an unfair polish.

At Diamond Club we carefully select diamonds that have the best possible proportions to have an outstanding balance of brightness and light reflection.

The right cut allows to the diamond to use light adequately. A diamond with an “ideal” cut (image 1) reflects light from one facet to the other and scatters towards the top.

If the cut is “deep” (image 2), part of the light escapes from the right and left lower facets.

And when the cut is “shallow” (image 3) the light exits towards the bottom and does not reflect. At Diamond Club we carefully select diamonds that have the best possible proportions to have an outstanding balance of brightness and light reflection.

The cut has very often been related to the shape of a diamond. The shape of an uncut precious stone usually determines the shape of the diamond; more importantly, this decision remains to the experience of the polisher. The most popular shape is the “round” diamond. But one can find a variety of shapes, such as: emerald, princess, asscher, cushion, radiant, triangle, pear, marquise, oval and heart.

Diamonds reflect the more light than any other gem. When a diamond is 100% clear, the light enters to its heart without encountering any obstacles. It is very rare to come across a diamond that has been exempted by nature from any flaws… They are known as “flawless”. These flaws are like small scars and determine the “identity” of each diamond without diminishing their beauty. The lesser and smaller flaws you encounter, the brighter and rare the diamond is. The number, the size, the position, and the color of these flaws determine “clarity”.


Clarity is a parameter that has been established by the Geology Institute of America (GIA) and references to a specific scale. Starting by FL (flawless) where no flaws may be observed under a 10x magnifying glass to I3 (imperfect) where flaws are visible to the naked eye. A flaw in the middle or at the top of a diamond can easily influence the course of light and diminish the brightness of the diamond.

Most flaws must be magnified (x10) in order to be observed by an experienced craftsman. Up to SI (slightly imperfect) they can hardly be detected.

The weight of a diamond is calculated using the carat as a measuring unit. A carat is equal to 0.2 grams (a 5 carat diamond weights 1 gram). A carat may also be divided into points; meaning that a 75 point diamond weights 0.75 carats. Weight, does play an important role on a diamonds’ value, but it is not the only parameter to define it. Two diamonds of same weight may have completely different values if the other 3 C’s (cut, clarity, color) are different. It may happen that a smaller diamond may be more expensive because its cut, color, and clarity levels are higher. On the other hand if clarity, cut, and color are identical then their weight will make the difference. As bigger diamonds are harder to find in nature, their value does not increase proportionally. Therefore a 1-carat diamond costs more than twice a 0.5-carat.

At Diamond Club we take our time to explain in details every C of a diamonds’ identity and help you choose right.


danelian diamond color The best color is the one that has no color. As it transforms the diamond into a “prism” and allows the light to perfectly enter within and reflect at the top in the form of mini rainbows.

The color scale starts from level D (no color) to level Z (light yellow). The differences between the levels are imperceptible and therefore we find a various number of colors in the color scale. A diamond may seem to have no color but a closer and experienced look will show shadows that will determine its level on the color scale.

Color is also a very important factor to the value of a diamond. The differences between the different color variations might be slight… the difference in its value may be more than you think.


There also diamonds that are popular because of their color! These diamonds have been naturally gifted with color. They are known as “fancy diamonds” and the palette is generous. You may find them in several tones such as blue, green, yellow, pink and the very rare red. The high quality fancy diamonds are very rare and of great value. Their quality and the richness of their color are the main elements that mold their value and make so special.

Fancy diamonds have their own private criteria that determine their value. In this case, color works backwards. The more color is rich, the more precious a fancy diamond is.

5th C - Certificate!

At Diamond Club we have issued a 5th C: the Certificate. As important indeed as the other C’s, it is in fact the identity of each diamond. All diamonds are unique and different from one another. The 5th Certificate (or Grading Report) is a bit like a diamonds’ fingerprint, and our guarantee you have purchased no less than we have promised you.

What is included in a Certificate / Grading Report?

The grading report states the scientific factors of the diamond you’re about to purchase; detailing the cut (depth), the carat weight, the color, the clarity, the diamond’s shape, its symmetries and also characteristics such as fluorescence, raining and any imperfections it may have. It also includes a diagram of your diamond as a proof of belonging.

Who issues the grading reports?

To assure the authenticity of our diamond’s value, we only issue our certificate with the most credible gemological institutions in the world. The GIA (Gemological Institute of America) and the HRD (Hog Raad Voor Diamant); both institutions are very famous for their experience and excellence.

A diamond should always be purchased with a GIA or HRD certificate as it allows you to understand in detail the diamond you’re about to purchase and even compare prices on the market.

At Diamond club we believe the 5th Certificate is as important as the other 4C’s because, by its nature, it guarantees the other 4C’s that make your diamond beautiful, bright, unique, and timelessly valuable!

Authenticity, brilliance, and value follow the Danelian reputation as a lifelong guarantee.
