As early as ancient Egypt, ancient Greece and Rome, it was used to decorate mosques, churches and monasteries and as a tribute to religious ceremonies. Together with diamonds and pearls, it has also become an indispensable ornament on the crowns and dresses of the kings of the British Empire and the czars of Russia.

Buy a sapphire, light.
It is best to observe sapphire with naked eyes under white light, not with strong light, because the blue color seen with naked eyes under white light is the most correct. High-quality sapphire should be transparent. When you turn the polished sapphire, you can see dancing blue light.
Second, flaws and colors.
It is best to buy sapphire without cracks and defects, and sapphire with obvious cracks is of little value. From the color point of view, purplish sapphire in indigo is the most precious.
Third, identification skills.
The identification method of natural sapphire and synthetic sapphire is: first, look at the texture and whether the texture structure is naturally crystallized. Rock crystal is often messy, so it is generally genuine.
However, the crystallization of synthetic sapphire is often very orderly. Of course, many synthetic sapphires are clean and flawless, usually fakes. Because there are always some impurities in natural gems, there are almost no clean ones.
This synthetic sapphire is often dazzling in color and superficial in luster, without the deep feeling of natural color. Natural gemstones are high in color purity, not dazzling, and their brilliance is naturally emitted from the inside out.
Sapphire maintenance 1, timely removal, which is also an effective maintenance of sapphire. In normal life, no matter how careful you are, some bumps are inevitable. Therefore, it is best not to wear sapphire when doing heavy work or sports, so as not to break the gem due to collision.
2. Don't let sapphire be contaminated with oil. Any gem will lose its original luster once it is stained with oil. Therefore, before entering the kitchen, it is best to take off sapphire jewelry. In addition, don't always touch the gem with your hands, because people will also have oil secretion on their hands, which will also affect the luster of the gem.
3. Sapphire can't touch substances containing acid and alkali, which will damage the gem. Therefore, gems should try to contact cosmetics, perfumes, soaps and other items that may contain acid and alkali substances. At the same time, remember to wear jewelry in order, make up first, and then wear gems.
When you go out every day, remember to take a small jewelry bag with you to avoid breaking the picked jewelry when washing your hands in the sink.
5. Sapphire jewelry that is often worn should be "examined" once a month, and go to the jewelry store to see if the gem is loose.
