Exposure to the hot sun and human sweat caused by high temperature may become a "jewelry killer." If you don't "serve" them carefully, they will crack, lose their luster, or may be scrapped ... what jewels can't stand the heat in hot summer?
Summer wear advice
Avoid outdoor high temperature and strong light.
The high temperature and strong sunshine in summer will destroy the surface structure of some jewels and jade. For example, jadeite is afraid of high temperature, which will lead to discoloration or cracking in case of fire. Turquoise/coral/amber is not heat-resistant, and amethyst/topaz/ruby loses its luster easily.
Avoid the erosion of human sweat.
After wearing jewelry in summer, remember to wash it with clear water or professional emulsion, dry it with a towel and keep it dry. Jewelry is not suitable for sports, swimming, sleeping and housework.
Avoid chemical pollution.
Wear jewelry in the last step of daily makeup, avoid applying perfume, bleach, cosmetics and other chemicals on jewelry, and pay attention to disinfecting alcohol. Sunscreen with high oil content will make the diamond with strong adsorption lose its luster. In addition, swimming pools or saline seawater will corrode precious stones such as corals/pearls/ivory.
Avoid sudden temperature changes.
If you take a bath with cold water just after taking a steam bath, the gold ornaments you wear may not be able to stand the pressure of contraction and expansion, and the gems in the ornaments are more likely to crack.
Tips for cleaning in summer
Cleaning mode
You can put the jewel ornaments in diluted soap solution, gently wipe the jewel and bracket with a soft brush, then rinse them with clear water, and then absorb the water with a soft cloth. Remember to plug the washbasin or fill it with pots to prevent jewelry from falling into the sewer.
Some precious stones, such as cracked jade, emeralds, opals, etc., should not be cleaned by ultrasonic machine, but can be wiped with soft dry cloth.
Fingerprints and stains on the surface of precious metals can be removed by non-abrasive cloth (such as silver cloth or glasses cloth).
Never use washing powder and detergent containing abrasives, and never use bleach to clean gold ornaments to avoid discoloration and decomposition.
So, in the hot summer, what common jewels can't resist the heat?
1. Diamond
How come diamonds don't shine after wearing them for a while? What about the good "fire color"? Did you buy a fake?
Of course not!
As the hardest mineral in nature, diamonds will not cause any harm if worn daily. However, it has a little-known feature, which is lipophilicity.
This feature in daily life is the oil secreted by the human body, daily skin care products or cosmetics, cooking fumes, etc. in the process of wearing diamonds. Will be adsorbed on its surface, affecting its reflection and refraction of light, thus reducing the luminosity and becoming dull.
In summer, when you sweat more and secrete more oil, it is easy to make diamonds "dull".
Maintenance coup:
Cleaning diamonds contaminated by oil stains is not a technical job. Just prepare a small bowl filled with warm water, mix a proper amount of neutral detergent in the water, put the diamond in it, and gently brush it with a toothbrush to easily remove the oil on its surface (don't brush it with toothpaste).
After brushing the diamond clean, block the drain and rinse it with clear water to restore its old flame color! Of course, don't forget to wipe off the water stains with cotton-free flannel and put it in a ventilated place to dry naturally.
2. golden
Although gold itself is stable in nature, it is easily corroded and dimmed due to contact with chemicals, and even discolored phenomena such as white spots (when encountering mercury), erythema (when encountering iron) and fading (when encountering sweat, cosmetics and skin care products) appear.
In hot summer, sunscreen, shower gel, shampoo ... these chemicals need to be contacted more frequently than usual.
Maintenance coup:
Don't touch chemicals when wearing gold. It is also not recommended to wear gold when bathing, cooking, swimming, exercising, soaking in hot springs, steaming sauna, dyeing hair and caring hair.
If you feel dull, you can gently scrub with a soft brush dipped in neutral soapy water (thick rice soup can also be used) to help you recover as new.
Apply a layer of transparent nail polish on the surface of gold every day, which can isolate the air and last forever ~
If the dirt is killed and cleaned, it is recommended to send it to the gold shop and ask professionals for help ~ Never burn it with a lighter at home (the guns in the gold shop will not be damaged)!
3. Emerald
Emerald contains many inclusions, so it is afraid of sun exposure (high temperature).
Long-term direct sunlight, jadeite can not stand "destruction", will produce cracks; In daily life, we should also try to avoid fire sources, otherwise we will lose its original luster and brightness.
Maintenance coup
Try not to wear emeralds in hot places with strong ultraviolet rays. Emerald is very delicate. Avoid bumping and beware of damaged edges and corners. When you need to engage in manual labor or strenuous exercise, you should take off your jewelry to avoid collision and crack of the gem. You'd better take it off when cooking. Don't casually wear skewers to eat hot pot!
More importantly, don't take it to the ultrasonic cleaner for cleaning! Wash and crack!
4. pearls
Pearl really deserves to be called the "queen of jewels", and the weakness of the nobility is obvious. Not only afraid of corrosive cosmetics, but also human sweat and even hot water will do harm to them. If you are not careful, your beloved pearl will become "old yellow" in a summer.
The physical properties of aragonite minerals that make up pearls are unstable and will become ordinary calcite after a long time. Although aragonite and calcite are both calcium carbonate in chemical composition, their physical forms have their own characteristics. That's why it turns yellow.
Maintenance coup
What should I do if the pearl turns yellow? The correct cleaning method is: soak pearls in 50-60 degrees pure water for 8- 10 minutes, and then clean them with a fine-wool toothbrush. Never use toothpaste.
turquoise
Turquoise is a hydrated copper-aluminum phosphate minerals, which has a loose structure and is not resistant to external factors such as bumping, drastic temperature difference change and large amount of water loss.
Any improper maintenance may cause turquoise cracking, and sun exposure will make water loss faster and accelerate the formation of cracks.
Maintenance coup:
Avoid exposure to the sun. Turquoise love the water. It is suggested that you soak turquoise in purified water regularly to achieve the effect of maintenance.
The soaking time is one night. You can take out the turquoise when you get up the next day, air-dry it naturally and put it in a sealed bag. Don't rush to let it dry quickly in the shade, put it under air conditioning, it will peel or crack.
6.aquamarine
Aquamarine is sky blue or sea blue because of its high iron content, and its color is as blue as sea water, so people give it the property of water. Belonging to the beryl family, it has emeralds and is also "brittle". Prolonged exposure to high temperature may cause the gemstone to discolor or even burst.
Maintenance coup:
When you wear it out in hot weather, you must do a good job of sun protection. Aquamarine is fragile, afraid of high temperature, high temperature and explosion, and will fade when baked in fire.
Avoid impact when wearing, and stay away from fire sources. Don't use ultrasonic cleaning machine when cleaning, but soak it in mineral water for 24 hours and dry it naturally before wearing it.
