A colored diamond is a tonal diamond that is more expensive than a regular diamond because the color of the colored diamond is very beautiful and extremely rare. So, how are colored diamondsgraded?
The Gemological Institute of America (GIA) has developed the well-known diamond 4C standards Carat, Cut, Clarity and Color. For yellow diamond grading, appraisal agencies are more focused on the color of the diamond. The color description of white diamond, from D to Z, indicates the degree of relative balance without yellow color. Only the yellow color beyond Z color can be called Fancy, the general diamond grade yellow diamond custom birthstone rings.
Many people say that it is difficult to buy a colored diamond because of its wide range and everyone has different feelings and preferences about the color. The color of the colored diamond is divided into solid color and mixed color. The color mixed color is very special birthstone necklaces. The visual effect is good and the price is cheap. However, there is always someone who pursues “pure”. The thicker the color of the solid color diamond, the more expensive it is. Therefore, the price identification of colored diamonds is different from that of colorless diamonds. It is very direct, the color is purer and thicker, and the price is more expensive. However, the investment value of the mixed color diamonds is lower than that of pure color diamonds, this is the basic difference.
According to the above rules, if you want to buy a yellow diamond with a vivid level, choose the ones you like to compare. According to the law of color, even the same level, the more concentrated the color, the more expensive.
Red and pink diamonds: Red diamonds are the most expensive of the colored diamonds, with low clarity. A small pink diamond name bracelet, if it is the Fancy intense, 1 carat will be about 2.5 million yuan. Unlike the yellow diamond, the red diamond has no other cause, such as nitrogen, but rather has its own distortion in the crystal lattice during its formation, through which the sunlight turns red. Pink diamonds are very rare, and diamond particles are generally small. From pink to red, red diamonds are rarer and more expensive.
Blue Diamond: The diamonds absorb a small amount of boron during their formation and become sky blue. The blue diamond has a high degree of clarity and is electrically conductive, making it suitable for industrial use. Finding a blue diamond with a vivid level is relatively easy, not as rare as a pink diamond. But it’s hard to find a beautiful blue diamond because it’s easy to gray.
The largest flawless brilliant blue diamond in the world was named “Blue”. This pear-shaped blue diamond weighed 13.22 carats and estimated at $21 million to $25 million before the auction. In the past ten years, only three 10-carat and rare-hard blue diamonds monogrammed necklace have been auctioned, and all three have not reached 12 carats and are defective. This diamond may be produced in the Premiere mine in South Africa, now known as the Cullinan mine. The market threshold for colored diamonds is set very high because they are too rare. And what’s unprecedented in the market is that there are customers who are looking for such investments. Christie’s auction house claims that the Geneva auction has set a record for seven jewelry auctions, including the yellow diamond with the highest historical transaction price – the 100.09-carat Graf bright yellow diamond ring, auctioned at $16.3 million. The auction house said it would also sell two diamonds of more than 100 carats, attracting buyers from more than 30 countries.
Green Diamond: Green diamond is very rare. It is caused by the lattice structure being altered by natural radiation to each layer during the formation of the diamond. There used to be a story: a diamond cutting expert, went to a mine to buy a green rough stone, then come back and want to cut a lot of green diamonds to sell. He did not expect that the deeper he cut the whiter the stone is. It turned out that the diamond only received radiation on the surface, and did not turn green inside, so he lost a lot of money. So the reason why the green diamond engraved necklace is so expensive, the first is that it is rare, the second is that the risk is very high, the money consumers spent is to compensate the risk of the merchant.
Orange Diamond: The orange diamond is the rarest of the colored diamonds, and it is rarer than the red diamonds, but it has no value because she has no collection value. In the collection of diamonds, only the main colors are collected: red, yellow and blue are what we call the three primary colors cute necklaces. The reason is simple, because they’re pure.
The auction of colored diamonds was extremely popular last year, and the 4C fine colored diamonds were the focus of the looting of various jewelry brands. Because they know that only if they capture the rare main stone, and the piece that carries it will have immortal attention.
