Diamond is the gem name of diamond, so it is also called diamond, sapphire and luminous stone. The English name is diamond, and the word * * * is the most difficult meaning. Greek calls it the world-beater "Atama Stone".
The high refractive index and high dispersion value of diamond lead to the special "fire color" of diamond. Modern science accurately calculates the best angle of refraction and cutting method of diamonds. Therefore, a well-crafted diamond can change into charming brilliance, and with its hard and eternal characteristics, it has become the cherished and pursued goal of the world.
The first diamond in the world was produced in ancient India about 3,000 years ago and was found in a valley called Krishna in India.
Until18th century, the rich king of India was the only supplier in the world.
From the 4th century BC to the beginning of the 8th century, India produced about 3 million carats of rough diamonds.
This is why diamonds are measured in carats.
A strange tree grew in ancient India. The weight of each seed in this tree is basically the same, and each seed is exactly 0.2 g.
Because diamonds are rare and have limited weight, clever Indians use the tree seed "carat" of this tree as the weight unit of diamonds.
The measurement unit of diamond weight is carat (CT), 1 carat = 0.2g, 1 carat = 100 minute.
In Europe in the13rd century, diamonds are the exclusive products of the royal family, and wearing diamonds is the privilege of the queen and princess.
Alice Su Hui, the mistress of French King Charles XVII, was the first woman to break this tradition. She got a diamond from the king and wore it in public. Since then, the diamond has entered people's hearts.
15th century is a milestone of diamonds and love.
Charles, Duke of Ba Gen, likes diamond rings and collects diamonds. When his daughter Mary was engaged to the Grand Duke of Austria, she was given a diamond ring, which became the first engagement diamond ring in history.
Since then, diamonds have become a symbol of beauty and eternal love, capturing the hearts of countless women.
16 and 17 centuries, the romantic French dominated the new trend of diamonds.
The necklace of French King Francis I is inlaid with 1 1 big diamonds. His queen Jia Fulian not only likes diamond jewelry, but also poisons political opponents by mixing diamond powder into food.
The "usurper powder" handed down in European history may refer to diamond powder.
Whether diamond powder is toxic or not has not been verified. It is very likely that the ancients deliberately fabricated lies to prevent miners from swallowing diamonds and stealing.
During the reign of Louis XIV, the popularity of diamonds in France reached its peak.
His palace is full of jewels and jade, and diamonds shine all over him.

The most famous is the 44 big diamonds bought back from gem giants, including a French blue diamond of 1 12 carats.

Americans are much later interested in diamonds than Europeans. It was not until the end of19th century that diamond jewelry became popular in America and regarded it as an eternal love message.
All this was created by the bachelor Harry Frederick Oppenheimer, the son of Sir Ernest Oppenheimer, who brought De Beers from the19th century to the 20th century.
The reason why Americans came from behind can be traced back to his promotion campaign, which is famous for the slogan "Diamonds are eternal".
It is said that diamond tycoon Brady owns 20 thousand diamonds; Pulitzer, a publishing giant, bought a necklace with 222 diamonds for his wife at the Royal Jewelry Auction in France. Famous movie stars Marilyn Monroe and Elizabeth Taylor have a beautiful story about diamonds, and the American people have deep feelings for diamonds. When the world-famous diamonds were exhibited in new york, thousands of spectators lined up in the rain to see them.
In Japan, until World War II, the number of people wearing wedding rings was less than 1% of the population. Later, De Beers launched an unpretentious but persistent promotion activity, which made nearly 70% brides in Japan wear diamond rings.
West Germans are another consumer group that is easily influenced by advertisements.
Before 1967, most brides in West Germany liked to wear wedding rings consisting of two gold rings, so De Beers put forward a new concept of "three-ring diamond ring", that is, adding a third ring with diamonds on the basis of "two-ring ring ring".
This new concept makes West Germany the third largest diamond consumer in the world.
China's earliest records about diamonds are the works of the Western Jin Dynasty, the sword of rolling chromium mentioned by Liezi Tang Wen, and the jade-cutting knife mentioned in the Romance of the Ten Kingdoms in the Han Dynasty.
These swords are all set with diamonds.

From marriage to wedding anniversary, lovers use diamonds to express their affection. A round ring with diamonds, which reads "Our love has no end", represents eternal love (this tradition originated from the West is also accepted by the East).

/kloc-in the 7th century, Portuguese explorers thought that "diamonds can grow near the earth's surface in 2-3 years", and confirmed this view by taking the example that miners can still get diamonds when they return to the old mining area several years later.
