The five most expensive gems in the world: 1 diamond

Diamonds are the hardest natural substance in the world. Since ancient times, people have used diamonds to symbolize men's strength and perseverance. When Pangu first opened hundreds of millions of years ago, diamonds were deeply hidden in the earth's crust, and they are still the hardest and lasting treasure in nature. It is precisely because diamonds can still shine after thousands of years that they have won the reputation of "eternity" and become a symbol of today's "eternal love". There are countless fairy tales about diamonds. The ancient Greeks believed that diamonds were the tears of God. It is said that Cupid's arrow can only exert the magic of love because of diamonds.

ruby

Ruby's English name is Ruby, which comes from Latin and means red. It belongs to corundum group minerals and has a tripartite crystal system. Because it contains chromium, it is red to pink. The higher the content, the brighter the color. Blood-red rubies are most cherished by people, commonly known as "pigeon blood red". Before the Middle Ages, all red gems were called rubies because of the underdeveloped scientific knowledge of gems. In ancient India, people believed that there was eternal fire in rubies. In the past, there was a tradition in the west that red gem ring was worn on the left hand, which showed that people were kind in nature, calm in heart and able to resist the temptation from outside. In addition, ruby is also a symbol of supreme authority and wealth. Therefore, in Britain, France and other countries, ruby is the main gem used to decorate the crown or royal symbol, especially in Israel, ruby is regarded as a symbol of the tribe. Ruby is the birthstone of people born in July, and it is also the memorial stone of the crystal wedding (the 0/5th anniversary of the wedding/kloc-) and the ruby wedding (the 40th anniversary of the wedding). It symbolizes nobility, love and kindness, and represents beauty, eternity and loyalty.

Ruby is hard in texture, and its name comes from its beautiful and full red color, which gives off strong vitality like fire. Her red color can be the same as you think: a pure and saturated almost mythical color, without any refraction of brown and blue. As the ancient Roman scholar Pushini said: "In the tiny space of gems, the whole nature is included. Only one gem is enough to show the beauty of everything in the world. "

Sapphire is produced in Thailand, Sri Lanka, Madagascar, Laos and Cambodia, among which the rarest sapphire belongs to Kashmir, and Myanmar is the place where the finest sapphire is produced today.

Natural sapphire can be divided into blue sapphire and bright (non-blue) sapphire. In the gem market, dark blue and purple sapphires are called "male sapphires" and light-colored sapphires are called "female sapphires". Sapphire is designated as "September Birthday Stone" by the international gemstone community, symbolizing loyalty and loyalty. It is said that sapphire can protect the country and the king from harm and is called "the stone of the emperor".

Because of its unique green color, unique charm and magical legend, it is deeply favored by westerners, and recently, it has been more and more loved by China people.

cat's eye

Opal, the mineral name is golden emerald. Because it contains rutile needle-like inclusions or feather-like fluid inclusions, from a proper point of view, refracted light will form bright light bands, which can change with the movement of light, like cat's eyes, hence the name. Opal is one of the five precious stones, mainly produced in Sri Lanka, Brazil and China.

The first five cardinal stones in western culture are diamonds, rubies, sapphires, emeralds and amethysts, but later amethysts depreciated due to the discovery of large-scale mineral deposits. With its increasing preciousness, the value of opal has been gradually recognized. Because of this, the world-recognized gems have now become diamonds, rubies, sapphires, emeralds and expensive olivines or opals.
