Therefore, strictly speaking, diamonds should be a diamond gem that made into jewelry, and diamonds that have not been processed gem value are called gem diamonds. However, because most people have called diamonds as habits. Therefore, people also mixed diamonds with diamonds.

    diamonds, also known as diamond, the mineral name is diamond. English is Diamond, which originated from ancient Greek Adamant, which means hard and inviolable substances.

    The chemical composition of diamonds is carbon, which is the only composed of a single element in the gem. The axis system of the genus. The shape of the crystal is mostly octopus, diamond -shaped duodang, tetraonal and clustering. Pure diamonds are colorless and transparent, which shows different colors due to the mix of trace elements. Qiang King Kong luster. The discount rate is 2.417, and the color is scattered, 0.044. Betal body. The thermal guidance rate is 0.35 calories/cm · second · degree. Test it with a hot guide, the most sensitive response. The hardness is 10, which is currently known as the hardest mineral. The absolute hardness is 1,000 times that of quartz and 150 times the jade. They are afraid of hitting. A group of explanations are complete. Density 3.52 grams/cubic centimeter. Diamonds are luminous. After sunlight, light green phosphorus light can be emitted at night. X -ray irradiation, emitting sky blue fluorescence. The chemical properties of diamonds are very stable, and it is not easily dissolved in acid and alkali at room temperature, and acid and alkali will not have effect on it.

    The difference between diamonds and similar gems and synthetic diamonds. Common substitutes or crickets in the gem market are colorless gemstones, color -free spine -free spine, cubic oxidation, titanic acid pupa, aluminum g utensils, tadpoils, and artificial golden stones. Synthetic diamonds were first successfully developed by Japan in 1955, but did not produce in batches. Because synthetic diamond costs higher than natural diamonds, synthetic diamonds on the market are rare. Diamonds can distinguish between gemstones similar to their unique hardness, density, scattering, and discounts. Such as: Cube of imitation diamonds is oxidized and colorless, with strong color scattered (0.060), strong luster, and density. It is 5.8 grams/cubic centimeter. Aluminum is soft and soft, and it is difficult to distinguish it from the diamond. Therefore, keep in mind the characteristics of diamonds when buying, so as not to cause unnecessary losses.

    Mozang diamond: It is very similar to the diamond. It is the latest diamond imitations-synthetic silicon carbide. It is a world patent product launched by the US C3 company to develop and research at $ 45 million and launched in June 1998. Its chemical composition is SIC, nearly colorless, with a discount of 2.56-2.69, a scattered 0.104, a double refractive index 0.043, a hardness of 9.25, and a density of 3.22 grams/cubic centimeter. Testing method: The heat guide instrument cannot distinguish between diamonds and Mosan diamonds. It must be identified by the US C3 company 590 color siliconless carbide/diamond detector. Test it with diet methane (density 3.32 grams/cubic centimeter) liquid. You can also use a magnifying glass to observe the package and fire burning method for auxiliary identification.

    The evaluation and purchase of diamonds should be considered from the following four aspects:
    (1) color: the best colorless, the darker the color, the worse the quality. Colorful diamonds, such as: red, pink, green, blue, etc., and belong to the treasures of diamonds, which are expensive.
    (2) Black defects: The degree of diamond cleaning should be carefully observed under ten times the microscope. The more defects, the more obvious the location, the worse the quality, and the price should be reduced accordingly.
    (3) Weight: The price of the diamond is proportional to the square. The greater the weight, the higher the value.
    (4) Cut: Cut it according to the standard ratio to form a standard round diamond type. If the proportion is not suitable, the price will fall without the "fire", and the price decreases. If there are fine lines and artificial injuries on the surface, the price will decrease.

    What is diamond?
    -The mysterious veil of the diamond
    The diamonds were formed deep in the strata hundreds of millions of years ago. It is a pure or nearly pure carbide formed under high temperature and high pressure.

    The precious parts of diamonds:
    . The natural conditions formed cannot be reproduced.
    . Finding and mining diamonds is a very difficult project and costs huge.
    . Diamonds are relatively rare than other gems.

    The extraordinary traits contained in diamonds:
    . Diamonds have a unique reflection ability for light. When the diamond is cut to an appropriate proportion, it can gather light and reflect the glorious glory.
    . Diamonds are the only essence minerals that do not contain other elements, and are the purest gems on the earth.
    . Diamonds are the hardest substances known to humans. But due to its unique internal structure, it will definitely be damaged if it is impacted. Diamond "4C": 4C is the four elements that evaluate the value of diamonds, namely COLOR (color), Clarity (clarity), CUT (cut), cact (weight).

    color color:
    The factor of color is important to diamonds, because the closer the colorless diamond is, the scarce the color, the higher the value. It is just a difference in color level, and diamonds of similarity can have different price differences.
    classification:
    The clarity is used to measure the quantity, location, type, color and obvious degree of the impurities contained in the diamond. When a diamond cannot find impurities or surface traces in a ten -fold magnifying glass, this diamond can be crowned as "perfect diamond". However, no flawed diamonds are extremely rare. In fact, almost all diamonds contain crystalline, feathers and cloud -like fine substances, which are also so -called impurities.
    CUT cutting:
    The brilliant brilliance of diamonds originated from precise cutting. In order to enable a diamond to radiate the best glorious diamond cutter, each cut surface and angle of the diamond must be arranged with precise geometric excessive arranges, and its effect is like light reflex mirror. For example, a round cut diamond. It is necessary to accurately arrange 57 or 58 cutting surfaces.
    carat weight:
    The weight of the diamond is represented by carats. One carat is equal to 0.2 grams. It can also be divided into 100 points. It is meaningless to pay attention to the size of the diamond. It must be considered at the same time, and it must be considered at the same time. If a diamond lacks brightness, clarity, high color and glory, even if the weight is large, it is not high. On the contrary, the greater the weighing weight of good quality, the less the value, and the higher the value.
    4C element is a global general standard for judging diamond value and preciousness when purchasing diamond jewelry.

  2. unfinished wood jewelry boxes wholesale The refractive index of diamonds is high, and the critical angle of full reflection is small, and it is prone to full reflection. In addition, the craftsman will carefully cut out the proper shape. The common 59 facial body and water droplet shaped, so that the full reflection is generated.

  3. jewelry wholesale online uk Physical internal rules, Fresnel formulas, the reflectivity of the calculated light, and the refractive index of the material. Generally speaking, the greater the refractive index of the material, the greater the reflectance, and the material with a high refractive index with a strong dispersion body, and the phenomenon of light scattering is obvious, so the diamonds are very reflected and dazzling.

  4. turquoise jewelry wholesale distributors The high refraction index of the diamond is small in the critical angle, and it is easy to occur with full reflection. Coupling artisans will be carefully cut, and the full score is appropriate. many.
