THE FOLLOWING MUST BE CONSIDERED WHEN PURCHASING A DIAMOND
Anyone who decides to buy a diamond should make sure that the diamond meets the high
quality criteria and therefore its value. Terms such as "flawless" are known to most buyers.
Most buyers are familiar with terms such as "flawless", but few realize that this quality feature alone is not enough.
The quality of a diamond is determined by the 4 Cs.
The weight of a diamond is in carats (abbreviated ct.). 1 carat corresponds to 0.2 grams and is divided into 100 points. Because of this, half a carat weighs 0.1 grams and has 50 points. Do not confuse the weight of the diamond with its size, which is influenced by both its size and the quality of the grinding. Important to know: if all the factors are met equally, then the diamonds with a higher carat are more valuable than those with a lower weight.
The word Carat comes from the Greek word "Keration" and is used as a name for the locust bean, a mathematical miracle of nature: each seed of the bean has the same weight. One metric carat corresponds to exactly 0.2 grams. Because of this, these grains were once used by jewelers as measures to determine the weight of Gold and of the precious stones.
Diamonds of all sizes are used for jewelry purposes. Brilliants over ¼ carats are perfect for solitaire rings. The following table exemplifies the different sizes of diamonds and their approximate diameter. It may vary depending on the individual polishing performance.
Diamonds are of different colors. For the value of a diamond it is necessary: that the more colorless the stone, the brighter it shines and thus it is more valuable. The white light penetrates and is reflected in the rainbow's color spectrum. The most valuable are the diamonds in the color "River" (= pure white"), followed by "Top Wesselton" (= fine white) and then "Wesselton" (= white, standard quality).
Depending on each laboratory, the color of diamonds is cataloged by different notions:
River, the most colorless, white-blue diamond bears the letter D and E.
F and G denote the pure white of Top Wesselton.
Wesselton diamonds are white and bear the letter H.
Meanwhile, more precious diamonds are being sold, the so-called Fancy Diamonds or "Fancies", diamonds with a more obvious and uniform pigmentation. Fancies actually account for a percentage of world production. First of all, diamonds in deep red and pink are very rare and thus very expensive. The most expensive diamond at the moment, a pink and emerald gemstone, weighing 24.7 carats, has been auctioned by a diamond dealer for no less than 46 million Dollars.
A diamond is purer and more valuable, the fewer inclusions it has. Inclusions mean the included minerals, spindles or growth marks, which influence the optimal penetration of light through the diamond. For diamonds like jewelry, it is important that the inclusions are not visible to the naked eye or at least not at first glance. If diamonds serve as a capital investment, then the high degree of purity plays a very important role. Flawless diamonds, which do not show inclusions even at a tenth magnification, are the purest diamonds and thus the rarest. The official assessment is made from FL/IF (flawless) to P3 (coarse inclusions). Detailed diagram:
|FL||Flawless||Lack of inclusions and external features|
|IF||Internally Flawless||No inclusions|
|VVS1-VVS2||Very, Very Small Inclusions||Very, very small inclusions, at a tenfold increase|
|VS1-VS2||Very Small Inclusions||Very small inclusions, at a tenth increase|
|SI1-SI2||Small Inclusions||No inclusions observed with the naked eye|
|P1-P3||Piqué||Inclusions visible to the naked eye are observed|
In the case of smaller diamonds, purity is normally classified as less pure. For example, instead of VS1 or VS2, it is indicated only VS or even just one domain, such as VS-SI. But the inclusions are also what make a gemstone unique.
All diamonds purchased from 123GOLD have a minimum SI quality (small inclusions).
The cut of a diamond determines the brilliance of a gemstone and thus is the criterion that significantly influences the beauty of a diamond, because the proportions are decisive for the reflection of light. The ideal cut has an extraordinary brilliance, the best proportions and symmetry. In the case of excellent cut, the brilliance, proportions and symmetry are excellent. Brilliance oscillates between “very good” (=excellent brilliance), “good” (=good brilliance), “medium” (=fair brilliance), or “unusual” (=poor brilliance) graduation. In the case of proportions and symmetry, the deviations become larger with the decrease in the quality of the diamond.
|Excellent||Optimal cut||The best possible brilliance, without foreign features|
|Very Good||Very good cut||Excellent brilliance, few or only insignificant foreign features|
|Good||Good cut||Good brilliance, some foreign features|
|Fair||Medium cut||Decreased brilliance, more foreign features|
|Poor||Minimal cut||Visibly diminished brilliance, many and/or great foreign features|
Each diamond in a piece of jewelry is polished into a specific shape. The most beloved shape is the one with polishing in 57 facets. In addition, there are many other shapes such as the Princess, Emerald, Heart, Oval, Marquise or Drop sanding types.
In the case of polishing, the skill of the man who processes the diamond matters a lot. The purpose of a perfect polishing is the optimal reflection of the light through the facets. The well-polished diamonds reflect almost all incidentals light.
