Diamond color classification 1, natural diamond color-colorless.
Colorlessness in diamonds can be divided into two series, one is colorless and transparent, and the other is pale yellow. This kind of diamond is the best of all diamonds. In the color classification of colorless diamonds, the top color is D, which is arranged down to Z in turn. We only say that the color scale from D to J, D-F is colorless and G-J is almost colorless. There is basically no collection significance from k down, but the ring holder below k color will also look good. Of course, the higher the grade, the more expensive the diamond is.
2, the color of natural diamonds-color
Colored diamond is divided into yellow diamonds, red diamonds, blue diamonds, pink diamond, green diamonds and black diamonds. Diamonds of all colors are rare treasures. Colored diamonds are mainly due to the color produced by the change of particles in colorless diamonds. Different changes produce different colors, so the rarer the color, the higher the value.
Their color difference is mainly due to the absorption of different trace elements, resulting in different colors. When nitrogen atoms replace some carbon atoms in the diamond crystal, the diamond becomes a yellow diamond, and the diamond begins to absorb blue and purple light, thus turning the diamond yellow. Blue diamond is a kind of diamond that absorbs a small amount of boron during its formation and becomes sky blue. Red diamond is a kind of diamond, and its lattice structure is distorted during its formation, making it appear red. The green color of green diamonds is due to the change of lattice structure by natural radiation. These colored diamond are also rare among diamonds and are expensive. Among them, red diamonds are the most precious.
What color diamond is the best?
The fineness of diamond ring mainly depends on the color grade of diamond, which is divided into white diamond and colored diamond. The rings we usually use to propose or get married are mainly white diamonds. The color grades of white diamonds in China range from D to M, and D is the highest color grade of diamonds, which is completely colorless. E color is colorless, and only professional appraisers can detect trace colors; Although F color is colorless, a small amount of color can still be detected. G to h are nearly colorless. When this grade of diamond is closely compared with D and E diamonds, a slight color will be found. I to j colors are also close to colorless, and it is easier to detect slight colors than previous levels; The colors K to M can be seen clearly with darker colors.
In fact, the color of a diamond depends entirely on personal preference. In addition, to judge the quality of a diamond, in addition to color, we should also pay attention to clarity, carat weight and cutting.
