For thousands of years, diamonds have been considered THE gem of the 21st century. The mineral is coveted, especially in its colorful version. Ever used for making beautiful jewelry, the color diamond is one of the most sought-after minerals in the world because of its refined color patterns.
Colorful diamonds: real jewels of nature
For jewelry lovers, colored diamonds are highly appreciated for the distribution and intensity of their color. It must be known that these precious stones are more rare than colorless diamonds. The diamond indeed takes its color from the chemical elements present in the earth, pressure conditions and particular temperature. Iron, aluminum or hydrogen are the most famous elements in giving the diamond its subtle color. Another peculiarity of colored diamonds is that the more intense the color of the stone, the rarer it is. They are stones of exceptional purity that their value is among the most important of the market, although it is not so much the purity of the stone that defines its value, but its hue.
As a general rule, there are two classifications for colored diamonds. When the gemstone has a solid color, the color "straight" indicates that the stone is unique in color. When the diamond is composed of several colors, it is then a mixed diamond indicating that the stone has other intensities of color than its dominant hue. As for diamond dealers and jewelers, the intensity of the stone is a benchmark for its elegance and refinement. For each gem, a specific name identifies a stone according to its intensity. From the least intense color to the most intense, the colored diamond is referred to as "fancy light", "fancy", "fancy intense" or "fancy vivid".
Exceptional stones of great rarity
Understanding the particular language of diamond dealers and jewelers is always essential to get a first idea of the value that stone can have on the market. It should be understood that although there is a wide range of diamond color, single color stones are the rarest on the market. Mixed-color stones are the most common types of colored gems. In addition to their elegant color, minerals are found mainly in mines in Australia, South Africa, India or Siberia. In other words, it is not given to all to find a colored diamond, and for that you really have to take the prize. The logic is such that the more the stone is rare, the higher its price on the market will be high.
Many still do not know it, but you have to count a colored diamond for a thousand colorless diamonds. If the colored diamond is known for its rarity, some colors are even more difficult to find. Red, yellow, blue and green diamonds are currently coveted, although these color schemes are simply rare. The deposits of these colored diamonds are very rare in nature. Given the invaluable value of these models, it is especially investors and collectors who allow themselves to afford these gems, and even find them at the other end of the planet. Of course, world celebrities do not hesitate to proudly display their colored diamond, thus contributing to the international reputation of these colorful gems.
The colors pink, red, purple and yellow in the spotlight
Around the world, a little more than a dozen diamond colors are currently known. However, four shades are now on the front of the scene, especially because of their rarity. At the top of the list, the pink diamond associated with femininity and romance is extremely rare. In reality, this hue can range from deep raspberry, or even red to pastel pink. To get an idea of the invaluable value of this colored diamond model, it should be noted that a 0.25 carat red diamond of oval size was sold for $ 326,800 in 1996. To date, The largest known pink diamond deposits in the world are found in Tanzania, Africa, Australia, Brazil and Russia. Otherwise, the presence of hydrogen in the red stone also produces very subtle violet shades. This colored diamond pattern is mined primarily in the Australian Argyle mine. The violet diamond is often very small, and the precious stones of an intense violet color without even more rare, whose extraction in the year is practically held in one hand.
By the way, the yellow diamond can also be considered the king of colored diamonds. The yellow color of the stone comes from the presence of nitrogen that will simply capture the sun's rays and offer the stone an extraordinary shine. Yellow diamonds are highly sought after and the most beautiful of them come from South African mines. Of undeniable elegance, yellow diamonds are classified into four color levels depending on the intensity of the yellow. All shades of yellow can be found on diamonds, with different intensities from one stone to another. The more intense the yellow, the higher the price of the stone. Nevertheless, the yellow diamond pattern is more answered than other colors, but still on small stones.
Other subtle colors known to date
In addition to red, pink, yellow and purple, there is a large choice of diamond colors. From blue to gray, to green and orange, all these precious stones have natural shades. We can first mention the blue diamond which has the particularity of absorbing all wavelengths of light, except for blue. The stone holds its hue of the presence of boron in its molecular structure. Renowned for being mysterious stones, blue gems are mostly found in India and South Africa. Its hue can go from the sky blue to the deep blue of the ocean. Another color of the diamond, green comes from a natural irradiation of stone, a formation that requires several million years, making the green diamonds the rarest in nature. Concretely, the green color results from the natural exposure of the diamond to the radiation of uranium. From intense meadow green to light mint, this diamond range exists mainly in Africa.
Often confused with green diamonds, olive stones are distinguished by their unique hue, a subtle blend of green and yellow. Sometimes it is even possible to find stones with a touch of gray and brown. Approaching colorless diamonds, gray diamonds have a silver hue, which only an experienced eye can make the difference with its colorless counterparts. This range of diamonds is very rare, just like the purple diamonds. It is a color resulting from the crystalline distortion of pink diamonds, a gem extracted in small size, most often in Siberia. Excellent alternative to yellow diamond, brown diamonds offer golden tones, a more delicate and soft version of colorless diamond. This color can range from deep cognac shades to light champagne. Native to Australia, Africa and Siberia, these brown stones are produced primarily in the Argyle mine. Finally, jewelers and diamond dealers also have diamonds with a solar and luminous aura. This range of orange diamond offers a color ranging from light orange to blood orange, with shades of pink, yellow or brown.
