Emerald is one of the most recognized precious stones in the international jewelry industry. Because of its unique green and unique charm, as well as magical legends, it has been favored by Westerners. Recently, it has become more and more popular among Chinese people.
The color of emerald emerald is very attractive. Some people describe it with spinach green, green onion, and green bud green, but they can't accurately express its color. It has a yellowish green color, and it seems to have a little blue. Even the spectrum seems to be missing the dot wavelength. Indeed, no natural color makes the eyes so comfortable. Whenever you look at the verdant lawns and leaves, the pleasing sensation is imaginable, but it is inferior to the emerald color. It is one of the gemstones that can never be seen. Whether it's cloudy or sunny, whether it's an artificial light source or a natural light source, it always glows softly and radiantly. This is the king of green gems - the charm of emeralds.
Emerald is a gem-quality green beryl. The green color should reach medium to reach a rich green tone, that is, the concentration of the color should be relatively saturated. Light green is often referred to as green beryl.
The beryl is produced by nature and its main component is Be3Al2[Si6O18], which has a hexagonal symmetrical aluminosilicate mineral. Emerald is formed due to the proper amount of Cr2O3 (0.15~0.6%). It is the most outstanding member of the beryl family.
The English beryl is beryl, which is derived from the Greek beryllos (green stone) and evolved from the Latin beryllus.
Emerald English is emeralde, from Persian zumurud (Emerald), later evolved into Latin smaragdus, and rumored to esmeraude, emeraude, and then become the current English spelling. Chinese is transliterated. Tao Zongyi transliterated in his "è¾è€•å½•" as "helping wood thorn". The old fashions in our country are called “Mother Green†and “Help Water Greenâ€. Hong Kong is also known as "Luzon Green".
Emerald has been one of the precious stones since ancient times. According to legend, 6,000 years ago, there were people in Babylon who presented it to the statue of the goddess. In the ancient Chaldeans of the Persian Gulf, women especially love emerald jewelry. Ancient Egypt and the ancient Greeks thousands of years ago also liked to use emeralds for jewelry. Chinese people are also very fond of emeralds. The emperors of the Ming and Qing dynasties were especially emeralds. The Emperor of the Ming Dynasty regarded it as precious as the golden-green cat's eye, and said that "the ceremony requires cat eyes and emeralds." Ming Wanli Emperor's jade belt is set with a large emerald, which is now in the Ming Tombs of the Ming Tombs Museum. In addition to the large number of pearls and other precious stones, the golden silk casket covered by the Empress Dowager Cixi has two emeralds weighing about 5 yuan each.
Now, emerald is the birthstone of May, symbolizing luck and happiness. Wearing it will bring people a lifetime of peace. It is also a memorial stone for the 55th anniversary of marriage.
As a high-grade gemstone, emerald has long been cherished by people for a long time. According to data research, its findings can be traced back to the 16th century. The mining of early emeralds was accompanied by the bloody evils of aggression and plunder.
It is known that the earliest emeralds were produced from schist deposits in southeastern Cairo, Egypt. Excavated by slave labor in 1500 BC or earlier, from ancient times to the 18th century, it was in turn owned by Egyptians, Greeks, Romans and Turks. It was abandoned in 1740 due to the depletion of resources, and all the information was lost, so that some people now think that there has never been emeralds, but all imported goods. At present, Egyptian emeralds are actually difficult to identify, and no samples are kept to be known.
Central and South America are currently the main producers of emeralds in the world. As early as 1521 when Spain invaded Mexico, there was a record of looting emeralds. In 1532, when Spain invaded Peru, the aggressors offered the plundered emerald as a gift to the king in order to please the king.
