Let's take a look at this diamond first. In 20 17, Arocha, a Russian diamond mining company, collected a 27.85-carat rough stone in the Far East and polished it, which is now the soul of the rose.
Why are diamonds expensive? This is mainly related to its own formation time. Diamonds are formed in the thickest and softest upper mantle layer under the hard surface of the earth. Most of them were formed 3.3 billion to 900 million years ago, long before dinosaurs appeared. This huge and long time is far from the appearance of human beings, but diamonds already have names, which makes sense.
It is understood that about 90% of pink diamond in the world comes from the famous argyle mine, and the mining area produces about 50 CT pink diamond every year, but most of them are small particles. About 654.38 billion carats of rough diamonds can be mined in the world in a year, which is less than 10% of gem-grade diamonds, and colored diamond can only account for one thousandth of this proportion.
As you can imagine, every auction in colored diamond will be a fierce battle. As the old saying goes, the rarer things are, the more people will compete for them.
Purple and pink diamond stones are really rare, and it is generally difficult to see them in the jewelry market. Usually, the price of a purple diamond with a purplish tone is around several hundred thousand dollars. However, purple diamonds with deep purple tones can only fetch more than one million dollars at auction.
In addition, I want to talk about diamonds of other colors. Yellow diamond is the most common variety in colored diamond, green diamond is very fresh and bright, and pink diamond is an aristocrat among diamonds, and the number is very rare. Of all the diamond colors, red diamond is the rarest, ranging from pink to bright red. The famous pigeon blood red diamond is a rare and priceless diamond, and it is also the most expensive diamond color. ?
