Angel's tears don't refer to a particular diamond. Angel's tears, originally a kind of plant, are full of leaves and are in the shape of water drops, just like tears, hence the name. Later, people made diamonds according to the shape of plant leaves, which were called angel's tears diamonds.
The story of angel's tears: angels pay attention to everything in the world in the sky, see the sweetness between men and women, see the sad state of one party's death, and envy their feelings at the same time, so they decide to go to the world to find out.
Finally, the beautiful angel found the man she loved and shed tears. Surprisingly, tears turned into diamonds. She told the secret of her life to the man she loved and they lived happily together. However, the good times did not last long, and men lost their freshness and were tired of angels. The angel noticed and left sad tears, which turned into crystals.
Tears left when you are happy are diamonds, and tears left when you are sad are crystals. This is what people give these two gems.
2. Ocean Star is one of the four giant gems in the imperial court of Mongolia. According to legend, it is used for divination and sky observation. The source is unknown, but one of the sources was plundered from a small Slavic country during the "eldest son's Western Expedition". The texture of the gem is blue, about the size of a seal. Its birthplace is Laitan (now Nogundi area in western Pakistan).
It is said that after being driven to the north of the Great Wall by Zhu Yuanzhang, the Mongolian Empire was lost during the migration of Mongolian nobles, and its whereabouts are still unknown. Some people claimed that when the Germans captured Kiev in World War II, they saw the Ocean Star in the underground vault of the Soviet National Bank, but it was not confirmed. "In the Center of the Sea" in the movie Titanic is based on "hope", a diamond with bad luck in reality.

1905, an original diamond mine weighing 3 106 carats was discovered in South Africa. The newly opened transatlantic cable quickly spread the news all over the world. At that time, experts in the gem industry estimated that the value of the original diamond was as high as $7.5 billion. As South Africa was a British colony at that time, everyone agreed to transport it to London and dedicate it to King Edward VII.
This unique treasure has aroused the imagination of jewelry thieves all over the world, and the relevant personnel have spent several months thinking about how to ensure transportation safety. Finally, Scotland Yard decided that the best principle was "the simpler the safer". Diamonds as big as eggplant were mailed in unmarked packages and appeared at the Royal Post Office in Buckingham Palace a month later.
On February 1908 and 10, this giant diamond was cut into several pieces for processing. The total amount of finished diamonds processed is 1063.65 carats, all of which are owned by the British royal family. The largest diamond is named Cullian 1 and weighs 530.02 carats.
