I bought a diamond ring at the beginning of the year. At first I saw that there was no impurities in the diamond, and it was very bright, but after half a year, I found that there were dark spots in the diamond! Diamond level is medium. What is the situation? What are the possibilities of this situation?

It is normal for natural diamonds to appear black spots. Flashing () Flash of Vajrayana is flashing, that is, when diamond or light source, the observer is relative to the surface of the white light reflection and flash. The colorless and transparent, good crystalline octagonal or curved polyphonic diamonds can show good flashing light even without cutting.
The color scattered or out -of -fire (or fire) Vajrayana's diverse crystal surface like three prisms, which can decompose white light inside the crystal into the color of white light through refraction, reflection, and full reflection — Blue,, purple and other color light.
The extension data In diamond crystals, the carbon atom is connected by the tetraonate key to form an unlimited three -dimensional skeleton, which is a typical atomic crystal. Each carbon atom forms a co -price bond with the other four carbon atoms with SP3 hybrid orbit to form a positive tetraonal body.
Because the C-C key in the diamond is very strong, all the price electrons are involved in the formation of the covalent bond. There is no free electrons. In terms of industry, diamonds are mainly used to make probes and grinding tools used by diamond probes. The shape is also used to make high -end decorations such as hand ornaments. The price is very expensive.

Natural diamonds are very normal.
of course, the black spots affect their value, and generally determine it as a flaw. According to the size and how much the black spots, the level of identification of the flaws. It can be seen under the magnifying glass. According to the level of net level, it is generally set at the level of SI. If it is visible to the naked eye, it will be set at the level of SI. It seriously affects its value.
It may be the reason why there is no cleaning. The dirt formed at the bottom of the oil, and try it to the store to try it.
That's the containing material of the diamond
