How to evaluate the value of diamonds? The value and value of the diamond is composed of 4C, 4C is the color, Clarity, Cut and Caratweight. 4C is the standard for identifying the quality of a diamond. Among them, color, clarity and carat weight are the innate conditions of diamonds; and cutting is the only human factor that affects the quality of diamonds. 3. Why are English and numbers engraved on the ring? Because the state stipulates that the precious metal must be engraved with the factory code and material color, you will see the relevant English and numbers on the finished jewelry such as the finger ring or bracelet. 4. What is carat? What is the point? Carat (ct) is an international gem quality unit. The weight of the diamond is expressed in carats. 1 carat = 0.2 g = 200 mg. When the quality of a polished diamond is expressed in carats, it is required to be accurate to two decimal places, and the third place is rounded off. For example, 0.598ct should be recorded as 0.59ct; and 0.599ct can be recorded as 0.60ct. The fraction (pt) is an international gem quality unit, which is mostly used for diamond measurement below 1ct. 1 carat = 100 points. For example: 0.10ct, you can call 10 points. 5. Is it ok to wear diamonds for housework and bathing? It's not impossible, but for your diamonds to be better maintained, try not to. Because diamonds have the characteristics of lipophilic, it is not advisable to bring diamonds to the kitchen to do things, nor to wear a bath, which is easy to hide. At the same time, although the diamond is hard but brittle, it cannot be used for a strong collision. If you find that your jewelry is dirty and shiny, you can contact us for a free cleaning service. 6. Will the diamond break? Most people think that diamonds are the hardest minerals in nature, so they won't break. This concept is not correct. This can be explained by hardness and firmness. Hardness: the anti-friction force of a substance; firmness: the ability of a substance to resist cracking and cornering. Although the diamond is the hardest mineral in nature, but because of its firmness, if the diamond's cleavage surface is struck, the diamond will break. Therefore, in daily wear, you must still be careful to prevent heavy blows. 7. The problem of gold fading: Generally, there are two possibilities: First, discoloration or fading is related to the sweat of the human body or the cosmetics used. 99% of human sweat is water, and about 1% is waste and harmful substances in the human body, such as: chlorinated substances, lactic acid, urea ammonia and so on. When these materials come into contact with silver and copper in gold jewellery, they produce a chemical reaction that produces silver chloride and copper sulphide and exhibits a deep black chemical salt. This chemical salt often falls from the gold jewelry, contaminating the wearer's skin, leaving a very noticeable black stain on the skin. At present, cosmetics have become one of the "characters" indispensable to people's lives. If it is applied to the skin where the gold jewelry is worn, it will undoubtedly provide opportunities for cosmetics containing chemical substances and gold jewelry that is most afraid of chemical attack. The result is conceivable. The general cosmetics contain mercury, mercury. When it comes to gold, it will chemically act, causing the gold to absorb the mercury part of the white. When this happens, the general maintenance master can use the welding torch to pass the fire once again to return to normal. Second, it may be that gold and white precious metals are worn together, resulting in the phenomenon of “golden eatingâ€. Gold adsorbs white precious metals, which leads to the white part of the gold. This situation can also be sent to the maintenance master for processing, and the weight will not be generated. influences. 8. Jewelry maintenance methods: The maintenance of platinum and palladium jewellery, especially jewellery inlaid with diamonds and precious stones, requires careful maintenance and necessary cleaning and cleaning to maintain the luster and perfection of platinum and palladium jewellery. What about the daily care of platinum and palladium jewellery? First, when doing strenuous exercise and heavy physical work, it is best not to wear platinum, palladium jewelry, which will cause accidental bruises, and even accidental loss. Second, if it is not taken for a long time, it needs to be properly preserved. It is best to keep the platinum and palladium jewellery separately from other different types of ornaments, because the hardness of each precious metal is different, and some colors are larger. The difference, when put together, will cause color changes, color mixing and other situations (such as the occurrence of gold). Third, if it is inlaid with precious stones, diamond platinum and palladium jewellery should be checked frequently, so as to avoid loosening and falling of gems and diamonds, and reduce accidental losses. 4. Do not wear platinum or palladium jewellery with diamonds and gems in the wet places such as kitchens and bathrooms to prevent the dullness caused by the absorption of grease. 5. Clean regularly: Platinum and palladium jewellery should be cleaned after wearing for a period of time. It is easy to lose the original brilliance without performing necessary cleaning for a long time. If it is only a small amount of dust, it can be washed directly with water [preferably boiled water], and gently wiped with a soft brush, soft cloth, etc. If the dirt is serious, you can use toothpaste, neutral detergent, it is best to buy professional jewelry cleaning solution, which can not only clean the dirt, but also increase the brightness of the jewelry. In addition, there are a few points to note when cleaning: (1): Do not use water containing bleach to avoid unpredictable chemical reactions.
