Jadeite
Jadeite jewelry is the most distinctive high-end jewelry of the Chinese nation. The maintenance methods are as follows:
(1) Clean it frequently. For jadeite jewelry, it is best to go to a professional store for cleaning, and check the metal claws and hooks in time.
(2) Do not contact with other gemstones and hard objects to avoid damage.
(3) Check the knots frequently to prevent them from falling off.
(4) If it is not used for a long time, it is best to wash it and store it separately.
(5) It is best not to wear jewelry during strenuous exercise.
Maintenance of gold and silver
[Silver]
1. The best way to maintain silver jewelry is to wear it every day, because human body oil can produce a natural and warm luster.
2. When wearing silver jewelry, do not wear other precious metal jewelry at the same time to avoid collision, deformation or scratches.
3. Keep silver jewelry dry, do not wear it when swimming, and do not approach hot springs and sea water. When not in use, wipe the surface with cotton cloth or tissue paper to remove moisture and dirt, and place it in a sealed bag or box to avoid contact with air.
4. If you find that the silver jewelry has turned yellow, the simplest way is to use toothpaste and a little water to gently wash the surface, or use a small jewelry brush to clean the fine seams of the silver jewelry, and then use a silver-cleaning cloth to gently wipe the surface, and the jewelry will immediately restore its original beauty. (If the silver-cleaning cloth can restore about 80% of the silver white condition, do not use silver-cleaning milk and silver-cleaning water, because they are all corrosive, and silver jewelry will become more likely to turn yellow after using these products. In addition, the silver-cleaning cloth contains silver maintenance ingredients and cannot be washed with water.)
5. If the silver jewelry is seriously yellowed, the soaking time in the silver-cleaning water should not be too long, generally a few seconds, and immediately wash it with clean water after taking it out, and then dry it with tissue paper.
6. If the silver-cleaning cloth can restore about 80% of the silver white condition, there is no need to use silver-cleaning milk and silver-cleaning water, because these products are all corrosive, and silver jewelry will become more likely to turn yellow after using these products. The silver-cleaning cloth contains silver maintenance ingredients and cannot be washed with water.
7. If you do not handle and store silver jewelry after wearing it, it is very likely to turn black. At this time, you should use a small jewelry brush to clean the fine seams of the jewelry, then drop a drop of silver cleaning milk on the tissue paper to wipe off the black oxide on the surface of the silver jewelry, and then use a silver cleaning cloth to restore the original brightness of the jewelry. After that, you must remember to do a good job of daily general maintenance to prevent the silver jewelry from turning black again. It is difficult to wipe silver jewelry white after it has turned black many times.
[Gold]
1. First, store gold jewelry separately in a jewelry box or suede, and make a habit of not throwing it together with other jewelry after wearing it to prevent scratches from occurring between them.
2. Place valuable jewelry in a safe place and purchase sufficient insurance. If you are not sure about the value of the jewelry, please take it to a local jeweler for an appraisal.
3. Clean gold jewelry regularly. This ensures that the jewelry presents the best luster and lasts longer. Gold jewelry should be cleaned the same way as other precious jewelry; use a commercial jewelry cleaner or soak it in a solution of soap and water and then gently wipe it with a soft cloth.
4. For gold jewelry with gemstones, it needs to be cleaned every six months. Have the jewelry adjusted, resized, polished and cleaned by a qualified jeweler. To professionally care for your gold, first make sure the jeweler has trained gold fitters.
5. If there are visible scratches, take the gold jewelry to a qualified jeweler for polishing. All precious metals may leave scratches, and gold is no exception. However, gold will naturally oxidize on the surface, so many people may prefer a freshly polished surface. If this happens, take your platinum jewelry to a qualified jeweler and have them re-polish it to produce an extremely bright effect.
6. Do not wear gold jewelry when doing housework, gardening, and other types of heavy work or physical activities. Because women are more likely to come into contact with bleach or harsh chemicals when wearing gold jewelry to do housework. Although they will not harm gold, chemicals may discolor diamonds or gemstones.
7. It is best not to wear or reduce the time you wear gold jewelry in the summer, because frequent contact or soaking in sweat will make your gold hair dark, and some women may experience itchy or allergic symptoms due to this reason.
For certain jewelry necklaces, due to the different qualities of different gemstones, there are some special requirements and precautions in terms of maintenance. They are introduced as follows:
(1) Jade necklace. Although jade is hard and tough and has a certain impact resistance. However, jade products after processing are often thin and can be damaged by impact.
(2) Emerald necklace. Emerald is slightly harder than jade, but more brittle than jade, so it is more vulnerable to impact and beating than jade. In addition, emerald is afraid of high temperatures. When exposed to fire, its color will fade and it is easy to crack at high temperatures.
(3) Opal necklace. Opal has a low hardness and should be avoided from friction with other objects. Opal contains water and should be avoided from high temperatures. Otherwise, after losing water due to evaporation, it will lose transparency at the least and crack at the worst. In addition, opal is not resistant to acid, so when wearing opal jewelry, you should avoid high temperatures and acidic substances. When collecting opal jewelry, you should also pay attention to the environment not being too dry, otherwise it will cause dehydration and cracks, or even breakage. To prevent dehydration, in the dry season, it is advisable to soak the opal jewelry in clean water once in a while.
(4) Amethyst necklace. The color of amethyst is unstable and will fade when exposed to high temperatures or long periods of exposure to the sun. When wearing or collecting, you should avoid high temperatures or exposure to the sun. Natural amethyst is known as the "guardian stone of love" and is noble and elegant, and is deeply loved.
(5) Malachite and turquoise necklaces. Both of these gems are harder than water and are very easy to wear. The chemical properties of both are unstable and will be corroded and dissolved when exposed to acid. Turquoise is particularly easy to change color at high temperatures, and even long periods of exposure to the sun and soaking in sweat will cause turquoise to change color. These are all things that must be paid attention to when wearing and collecting.
(6) Pearl and coral necklaces. Pearls and corals have very low hardness and can easily lose their luster due to friction. Both are composed of calcium carbonate, which will corrode and dissolve when exposed to acid. It is easy to sweat in the summer, and sweat can also damage the surface of pearls and corals and cause them to lose their original luster. Powders, perfumes, and hair lotions in cosmetics can also gradually cause pearls to lose their color. Therefore, it is best not to wear such jewelry in the summer. If stained by sweat, rinse it in clean water and then gently wipe it dry with a soft fabric. Pearl jewelry must be rinsed with clean water before collection, and must be stored away from cosmetics.
(7) Lapis lazuli necklace. Lapis lazuli necklaces must not be soaked or rinsed in water after being stained. Because lapis lazuli is a granular aggregate composed of multiple minerals, if it is soaked or rinsed in water, the dirt on the surface of the gem will penetrate into the interior, which will change the original luster of lapis lazuli. If lapis lazuli jewelry is stained, it can be gently wiped with a damp cloth to wipe off the dirt.
