How to prevent jewelry fading and maintenance

Gold Jewelry: The discoloration or fading of gold jewelry is closely related to the sweat of the human body. 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 of the gold jewelry wearing part, then it will undoubtedly provide opportunities for cosmetics containing chemical substances and gold jewelry that is most afraid of chemical attack, and the result can be imagined. Some cosmetics also contain some fine hard particles, which can form another type of dirt, thus consuming gold jewelry. Regional environmental factors may also cause gold jewelry to lose its bright color. For example, in a dry area, the air contains more original fine dust, which will form a kind of “human body sandpaper” when it is contaminated with the human body. It can rub the gold jewelry into extremely fine debris and appear partial black stains. It is worth mentioning that the talcum powder or moisturizer also contains similar particles, which will also eclipse the gold jewelry as mentioned above. Treatment: Brush with soapy water mixed with a little alcohol, rinse and dry.

925 Silver Jewelry: Generally, the sterling silver sold in the market is 925 silver instead of 999 sterling silver. Because 925 silver is an alloy silver made of other metals, such 925 silver is recognized internationally as In sterling silver, the ratio is 7.5% alloy and 92.5% silver. Such sterling silver forged jewelry is stronger and less prone to wear and deformation. The real 999 sterling silver is as soft as pure gold. The jewelry made of sterling silver will be durable, not deformed in a few days, and the surface wears too much and needs constant polishing. How to maintain sterling silver jewelry? The biggest cause of oxidation of silverware is oxygen in the air, so blocking air is the best way to maintain it. For example, put the silver in a sealed plastic bag and put it in a jewelry box to block the contact between the air and the silver. When oxidizing, you can use silver-washed water or silver cloth to polish the silver, but the silver-washing water has a strong killing power. Therefore, please wipe it with a silver cloth as much as possible. If you use silver-washed water, pick it up immediately. Flush and soften, and clean the surface of the chemicals, and blow dry with a hair dryer. Otherwise, the oxygen in the water will accelerate the cerium oxide! In addition, soak it in 90-degree alcohol for 12 hours, wipe it off and dry it; or squeeze the toothpaste on a dry cloth and wipe it directly. The effect is also very good.

Platinum Jewelry: For a long time, when an elegant and beautiful platinum jewelry brings you a good feeling, can you think of how to care for your beloved platinum jewelry, so that it always shines with you? Here are some simple ways to teach you. When you do housework, don't let the platinum jewelry you wear be stained with oil or bleach. Oil stains will affect the luster of the jewelry; bleach may cause spots on the jewelry. Although young you want to be eye-catching, you must not wear platinum jewelry and gold jewelry at the same time, because the gold texture is soft, if you rub each other, the gold powder will be adsorbed on the platinum, making the platinum yellow, affecting the pure luster of platinum. . If worn frequently, platinum jewelry should be cleaned once a month to maintain a shiny luster. It can be cleaned with special jewelry cleaner or cleaned by yourself. The correct way is: squeeze the toothpaste on the towel, rub it with platinum jewelry on it, remove the fine lines and dirt on the surface, then wash it with diluted household detergent, then rinse it with water. The gloss can be restored as new. If your platinum jewelry is set with diamonds, it is recommended that you send the platinum jewelry to the jewelry store every year for inspection and timely professional cleaning and refurbishment, so that platinum diamond jewelry is often worn. Just like beautiful flowers and plants need to be carefully taken care of, your platinum jewelry needs your care to spend a wonderful time with you.

Pearl Jewelry: Although the color of the pearl is very beautiful, it does not stand the test of time. Generally, after several decades, the pearl will become ordinary yellow, and at the same time, the beautiful pearl luster will be lost. This is what the saying goes, "the old man is yellow." Why does the pearl jewelry use yellow for a long time? This is mainly because the physical properties of the aragonite minerals that make up the pearl are unstable. Over time, it becomes an ordinary calcite. Aragonite and calcite, although chemically identical, have a different crystalline form and luster. This is the reason for the discoloration of the pearl. After the pearl turns yellow, there are some remedies, that is, soaking with dilute hydrochloric acid can dissolve the yellowed outer shell, and the pearl will reproduce the brilliant and radiant color. However, if the color becomes very powerful, it will be difficult to reverse. You should wear pearl jewelry after the makeup is finished, because any beauty products (powder, foundation cream, etc.) are harmful to the pearl, including perfume and hair gel. After wearing, the pearls should be washed with water, rinsed, dried, and then collected, otherwise the pearls tend to yellow.

Diamond Jewelry: Add water and detergent to the container, put your diamond ring in water for 10 minutes, soften the dirt, then brush it with a toothbrush, rinse it in water, then wash it with 90-degree alcohol. Finally take it out to dry.

Turquoise jewelry: Be careful when wearing turquoise jewelry, it can absorb grease. Do not wear turquoise jewelry when applying sunscreen or lotion to your body. Because once the dirt is dirty, it is difficult to restore it to its original state.

Opal Jewelry: Must be kept in a cool place. Because the egg stone contains a lot of water, it will dehydrate after exposure to the sun or strong light for too long. The method of care is to soak in water or sweet apricot oil for two days and it will be restored.

In addition to the above general principles, some jewellery has different qualities for different jewels. Therefore, there are some special requirements and precautions in terms of maintenance.

(1) Gemstone jewellery such as diamonds, rubies, sapphires, tourmalines, and topaz (ie topaz). These gemstones are hard and can withstand a lot of pressure, but they also have the common disadvantage of being brittle and cleavable for diamonds and topaz, so these gemstones can't withstand beatings and knocks, otherwise they will be brittle. And it collapses, or cracks or even breaks in the direction of cleavage due to cleavage. Keep in mind that even the hardest diamonds can't withstand the impact.

(2) Jade jewelry. Although the jadeite is strong and tough, it has a certain impact resistance. However, the jadeite products after processing are often thinner and will be damaged by impact.

(3) Emerald jewelry. The hardness of emerald is slightly larger than that of jade, but it is more brittle than jade, so it can't withstand impact and beat more than jade. In addition, emeralds are afraid of high temperatures, which can cause the color to fade and catch it at high temperatures.

(4) Opal jewelry. Opal has a low hardness and should be avoided from rubbing against other items. Opal contains moisture and should be protected from high temperatures. Otherwise, it will lose its transparency due to evaporation, but it will lose its transparency. In addition, opal is not acid resistant, so avoid high temperature and acid when wearing opal jewelry. When collecting opal jewelry, you should also pay attention to the environment should not be too dry, otherwise it will cause dehydration and cracks, and even break. In order to prevent dehydration, in the dry season, it is advisable to soak the opal jewelry in clean water for a certain period of time.

(5) Amethyst jewelry. Amethyst is unstable in color and can cause fading when exposed to high temperatures or exposure to prolonged exposure. Avoid high temperatures or exposure during wear or collection.

(6) Malachite and turquoise jewelry. Both gems are harder than water and are very susceptible to wear. Both of them are chemically unstable and will be dissolved by corrosion when exposed to acid. Turquoise is particularly discolored at high temperatures, and even a long period of exposure and soaking in sweat will also discolor the turquoise. These must be taken care of during the wearing and collection process.

(7) Pearl and coral jewelry. Pearls and corals have a very low hardness and are highly susceptible to tarnishing due to friction. Both components are calcium carbonate, which will suffer from corrosion and dissolution when exposed to acid. Summer is easy to sweat, sweat will also damage the surface of pearls and corals and lose their original luster. Powders, perfumes and hair creams in cosmetics will also gradually fade the pearls. Therefore, it is best not to wear such jewelry in summer. If it is stained with sweat, rinse it in clean water and gently dry it with a soft fabric. Before the collection of pearl jewelry, it must be rinsed with water, and the place must also avoid cosmetics.

(8) Lapis jewellery. After the lapis lazuli jewelry is smeared, it must never be soaked and rinsed with water. Because lapis lazuli is a granular aggregate composed of various minerals, if it is soaked and washed with water, the dirt on the surface of the gem will penetrate into the interior, which will change the original brilliance of lapis lazuli. After the lapis lazuli jewelry is stained, wipe it gently with a damp cloth to remove dirt.
