According to color diamonds can be divided into two categories: colorless series and color series. Colorless: We usually refer to white diamonds, with the letter D as the top color, and so on. The IJ color is light yellow (brown, gray). The colors are different according to the color.
1. Net Rhinestone: A colorless, transparent diamond that is as pure as water, with light blue being the best. The world's largest diamonds and world famous diamonds are mainly such varieties, such as "Jinkel" and so on.
2. Red diamond: a transparent diamond from pink to bright red, especially the "pigeon blood red" is a rare treasure. Australia is its main source, such as the world famous diamond “Russian Redâ€.
3. Blue Diamond: A clear blue, blue to dark blue transparent diamond, of which the dark blue is the best. This diamond, unlike all other color diamonds, has semiconductor properties. Because it is particularly rare, it is a rare treasure. Such as the world famous diamond "hope" and so on, South Africa's Premell mine is its main source.
4. Green Diamond: A light green to green transparent diamond, with fresh green as the best. Such as the world famous diamond "Dresden Green." Zimbabwe (Rhodessia) is its main source.
5. Purple Diamond: A lavender to purple transparent diamond, especially the rare purple is a rare treasure, the former Soviet Union is its main source.
6. Gold Diamond: A golden transparent diamond that is a common variety in colored diamonds.
7. Black Diamond: Black diamond is usually not used as a diamond, but a large black and transparent person can also become a precious diamond, such as the world famous diamond "African Star".
Color plays a very important role in the value of diamonds. One of the reasons why precious diamonds are precious is their rarity, and the probability of occurrence of various colors is different. For example, red diamonds are almost insignificant, green is also very rare, blue and purple are rare colors. In comparison, yellow, brown and other colors are relatively large, but overall, colored diamonds are still rare gems.
The jewellery industry generally recognizes that colorless diamonds are the best, while yellow and brown are poor; light red, blue and green diamonds are called colored diamonds and are precious diamonds. There are still no international evaluation standards for colored diamonds.
