4 thoughts on “What does the diamond ring mean two EXs mean?”

EX is usually used to describe cutting, and the purchased jewelry certificate is marked with diamond EX. The diamond shape and type of diamonds are mainly determined by polishing, symmetry and polishing process. Excellent cutting can exude dazzling light from all angles, especially in the sun. The cutting of diamonds from high to low is divided into five levels. The ideal type is based on the cutting of diamond EX. It represents the standard that can only be achieved by only 3 % of high -quality diamonds. It's like a very distinguished and beautiful craft. The expansion information: omotive structure four carbon atoms are combined around a carbon atom with common price bonds with shared electrons, and the four carbon atoms are the same. Short (0.154nm), so diamonds are the hardest materials. The hardness The diamond Mo's hardness is 10, which is the hardest material known. The hardness of Mohs is only the sequence of hardness, and does not represent actual hardness. For example, the hardness difference between diamond (10) and Gangyu (9) is that the hardness difference between Gangyu (9) and talc (1) is still large. The hardness of the difference The hardness of the diamond is not exactly the same. On the same diamond, the hardness in some directions is slightly stronger and the hardness in some directions is slightly weaker. The cutting of diamonds is to use this point. In a relatively hard direction of diamonds, another diamond is softer. Only diamonds can cut diamonds.

The expansion information: diamonds as ornamental gemstones: Diamonds appear to be shining under the light due to high refractive index, becoming a lady's favorite gem. Giant drills can be valuable. The price of a deep -colored diamond is higher. At present, the most expensive colored diamonds are a slight blue water and blue diamond. The diamonds are divided into two types: first and second type, which is mainly based on whether it contains n elements: first type; type 2 does not contain. The blue diamond is Type 2 and semiconductor.
Round diamond: generally cutting, symmetrical, and polishing. VG represents very good. EX is the best, G is good. In general, customization will choose 3EX diamond inlaid. Alien diamonds: generally symmetrical and polishing, with only two items. Some of the alien diamonds should not only look at this symmetrical and polishing parameter when selecting, but also look at the physical or high -definition pictures. The better shape of diamonds often cost higher prices.

omotive structure
four carbon atoms are combined around a carbon atom with common price bonds with shared electrons, and the four carbon atoms are the same. Short (0.154nm), so diamonds are the hardest materials.
The hardness
The diamond Mo's hardness is 10, which is the hardest material known. The hardness of Mohs is only the sequence of hardness, and does not represent actual hardness. For example, the hardness difference between diamond (10) and Gangyu (9) is that the hardness difference between Gangyu (9) and talc (1) is still large.
The hardness of the difference
The hardness of the diamond is not exactly the same. On the same diamond, the hardness in some directions is slightly stronger and the hardness in some directions is slightly weaker. The cutting of diamonds is to use this point. In a relatively hard direction of diamonds, another diamond is softer. Only diamonds can cut diamonds.

Among the three "cut, polishing, symmetrical", 2 dimensions reached excellent (perfect level)
Round diamond:
generally cutting, symmetrical, and polishing. VG represents very good. EX is the best, G is good. In general, customization will choose 3EX diamond inlaid.
Alien diamonds:
generally symmetrical and polishing, with only two items. Some of the alien diamonds should not only look at this symmetrical and polishing parameter when selecting, but also look at the physical or high -definition pictures. The better shape of diamonds often cost higher prices.
