  1. The black spots appear in the diamond to indicate that there are defects
    The clarity of diamonds of diamonds is mainly to watch whether there are impurities inside the diamond. Generally, it is necessary to observe it through high -power microscope. Quantity and other situations. The less impurities in the diamond, the higher the value, the higher the value, the better the transparency. Diamond clarity is 13 levels, according to the figure above, you can see the level comparison.

    is how much the connotation of diamonds under the large mirror. GIA divides diamond clarity into FL, IF, VVS1-VVS2, VS1-VS2, SI1-SI2-SI3, I1-I2-I3 and other levels. In this gear, the collection is more suitable for the IF.
    The comprehensive consideration of the purchase of SI1 when buying a diamond ring. This kind of cleanliness is high and looks good. Essence

    The color of diamonds is divided into 23 levels. From the high -quality colorless colorless color of D -class to the light yellow or brown color of Z -level, the level is decreasing step by step, and the quality is decreasing. There are several different levels of color levels:

    Among them, D color is a very good grade color, and it is also the color level that many diamond rings like to use.
    The colorless level: G, H, I, J, and the naked eye can hardly see any color, but comparing them with colorless levels will be relatively colorful.
    Mild micro -yellow level: K, L, M. It is generally difficult to see the color when watching it. If it is diamonds of more than 1 carat, the color will be relatively obvious.
    D yellow level: n, o, p, even the color that can be seen by the naked eye, few people choose such a diamond ring. As for the P -level, it rarely appears in the public's vision, because the jewelry industry has strict control of the diamond color grade, and most brands of diamond ring use

  2. 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.

    extension data
    In diamond crystals, carbon atoms are connected by the tetrahedron to form an unlimited three -dimensional skeleton, which is a typical atomic crystal Essence 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.
