Matters Needing Attention
Old silver jewelry should not be cleaned together with new silver jewelry, it will become dirty.

Avoid contact with daily chemical products to avoid chemical reactions such as soap, shower gel, shampoo, cosmetics, etc.
Avoid collision or force to avoid deformation or breakage, such as sports, sleeping, cooking to take off your beloved jewelry.
Avoid high temperature and exposure to the sun to avoid unnecessary fading and other problems.
Different kinds of jewelry, with different hardness, should be worn and placed separately to avoid mutual wear and tear.
Check your jewelry regularly, whether the claw-set stones are loose or not, whether you have lost diamonds, whether the necklace clasp is firm, etc.

More details:
Keep jewelry away from chemicals
Exposure to chemicals may damage or discolor precious metals (gold, silver and platinum) and may also cause damage to certain colored stones. Even everyday household products like hairspray, lotions, perfumes or other cosmetics contain chemicals that can permanently damage the surface of jewelry and other delicate or porous stones (such as Turkish stones). Always remove fine jewelry before diving into a pool that contains chlorine or using household cleaners. Many of these cleaners contain ammonia, which is too harsh for delicate stones or antique jewelry. Chlorine bleach is another common household solvent that can cause dents or damage to gold alloys.

Beware of light and heat
Just as the sun’s harmful rays can harm our skin, light and heat can affect the durability and color of colored gemstones. Over time and from excessive light and heat, certain stones can also fade and become damaged, such as amethyst, lithium amethyst, topaz and shell cameo. Pearls and other fine materials (such as ivory) can be bleached if they are overexposed to light. Other stones, especially amber, will become dull over time when exposed to too much light.

Excessive heat and sudden temperature changes may also fracture certain stones. Heat can easily remove the natural water content, and these gems depend on moisture to maintain their beauty. For example, pearls can dry out, crack and change color. Opals can turn white or brown, develop tiny cracks, and may lose their tourmaline color.

Tips For Gemstones Jewelry Special Care
Many colored gemstones and jewelry are often treated to improve their color and clarity. These treatments can be negatively affected by heat, solvents, steam and ultrasonic cleaning machines. Knowing whether a stone has been treated or not is the first step in understanding how to care for it. Important information about the gemstone and any detectable signs of treatment should be known before cleaning.

Tips For Maintenance Gold and Silver
It mainly refers to pure gold, 18K gold, silver, platinum, etc.
When gold jewelry loses its luster due to tarnish and dust infection, just put it in neutral detergent (PH value = 7) to soak and clean it with warm water, and then take it out and wipe it dry.
Silver jewelry blackened can be wiped with a silver cloth, you can also use the toothpaste without particles to clean.
Metal jewelry will be worn for a long time oxidation reaction fading, blackening, etc., these are normal phenomena, you can get gold store refurbishment.
Metal jewelry that is not worn for a long time, take an airtight pocket after cleaning to prevent oxidation and blackening.
PS: Old silver jewelry should not be cleaned together with new silver jewelry, it will become dirty.

Tips For Maintenance Diamonds
It mainly refers to ordinary white diamonds, yellow diamonds, pink diamonds, etc.
Don’t touch the diamond with your hands often, the diamond is oleophilic and the oil on your skin will affect the luster and brightness of the diamond.
Don’t wear and place diamond jewelry with other gemstones, because diamonds are very hard and will have wear and tear on other gemstones.
Although diamonds are hard, they are also brittle, so do not bump them.
To clean, fill a small bowl or teacup with warm water and mix an appropriate amount of neutral detergent (PH = 7, such as detergent) in the water. Dip the diamond jewelry in the water, brush it gently with a toothbrush, rinse it with warm water, and finally wipe it dry with a soft cotton-free lint-free cloth.
You can take it to a gold store and use ultrasonic waves to clean it, but group-set diamonds are the exception.

Tips For Maintenance Other Delicate Items
It mainly refers to colored gemstones, rubies, sapphires, emeralds, tourmalines, garnets, etc.
Because of their different hardness/different kinds of colored gemstones should not be worn and placed together.
Some stones are afraid of losing their moisture due to strong heat or wind, such as turquoise and opal, so avoid direct sunlight when preserving them, and avoid using a hairdryer when wearing them, etc.
For emeralds, tourmalines and some other stones with many inclusions, cracks or brittle nature and low hardness, do not use ultrasonic machines to clean them, as they may be damaged or shattered.
2. Organic stones
Mainly refers to pearls, coral, amber, beeswax, etc.
Organic stones contain organic components and are not very hard, so do not touch them.
Keep away from heat sources (hot water, exposure to the sun, etc.) and acidic and alkaline substances. Sweat, steam and fumes can damage gemstones with air pores (pearls, coral, etc.), so wear them in these places with cloudy gases, such as the kitchen.
Avoid using chlorinated tap water to clean pearls; use purified water. You should use professional pearl jewelry wiping paper, preferably with a sheepskin or bead wiping cloth to wipe the pearls.
Avoid using ultrasonic waves to clean pearls, because ultrasonic waves can seriously damage pearl jewelry.
