jewelry china wholesale Diamonds are mainly composed of carbon.
The diamond refers to diamonds that have been considered. Vajra is a natural mineral and the rough of diamonds. To put it simply, diamonds are a monomer crystal composed of carbon elements under high pressure and high temperature conditions of the earth.
The diamonds have the highest hardness in natural minerals, and their brittleness is quite high. It is derived from the ancient Greek adamant, which means hard and inviolable substances, and is a recognized king of gemstones.
cards, or translation of carats, carats, is the quality unit of diamonds. One card is equivalent to 200 mg. According to legend, the weight of the early diamond merchants' weighing diamonds is a carob fruit (carob) fruit. A fruit of one grain weighs about 200 mg. Because the density of diamonds is basically the same, the heavier the diamond is the larger. The larger the more diamonds, the higher the value of each card.
The chemical composition of the diamond is carbon, which is the only one composed of a single element in the gem. It often contains 0.05%-0.2%impurities elements, the most important of which are n and B, and their existence is related to the types and properties of diamonds. The shape of the crystal is mostly octopus, diamond -shaped duodang, tetraonal and clustering.
It pure diamond colorless transparency, showing different colors due to the mixing 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. Poinity and alkali will not have a effect on it.
The differences between diamonds and similar gems and synthetic diamonds:
The substitutes or pupae in the gem market are colorless gemstones, colorless spinels, cubic oxidation, titanic acid, aluminum g uterry, , 钇镓 Garnet, artificial golden stone. 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.
