The largest diamond in the world you asked is Cullinan diamond, 3 106 carats, which is equivalent to the fist size of an adult man. Cullinan was too big for anyone at that time. Later, it was acquired by the local authorities in Transvaal for 6,543.8+0.5 million pounds, and presented to the British royal family on February 9, 654.38+0.907 to celebrate the birthday of King Edward III. The crushing work was completed by the famous Dutch craftsman Jo Aschar. He spent several weeks studying Cullinan, made a glass model according to its size and shape, and designed a set of tools. He first tested the glass model with these tools, and the model was indeed split. After a few days' rest, in February 1908, 10, he and his assistant came to a special studio, clamped Cullinan in a big pliers, and then put a special steel wedge in a pre-ground groove on it. Joe Ashcar hit the steel wedge with a heavy stick, and with a bang, Cullinan did not move, but the steel wedge was broken. Cold sweat streamed down Ashcar's face, and he put a second steel wedge in an atmosphere as tense as an explosion. Knock hard again This time, Cullinan split in half as planned, while Ashcar fainted on the floor.

After being split, Cullinan was polished into 9 big diamonds and 96 small diamonds. The largest one is called "Cullinan 1", that is, "Star of Africa", which is embedded in the Queen's scepter, and the second one is called "Cullinan 2" which is embedded in the Queen's crown. It can be said that the Tianxi series is priceless, and its owner has inestimable wealth value.

As for the blue diamond-"hope". Also known as the "star of doom". Because everyone who once owned it is dead. It was not until 1958 that Winston, a famous American jeweler, was lucky enough to get this diamond and gave it to the country. After being collected by the Smithsonian Institution in Washington, USA, this bad luck ended ~ Maybe it was destined to belong to all mankind ~ The whole story is as follows:

"Hope" blue diamonds appeared 500 years ago. In an abandoned mine on the banks of the Keable River, an old man passing by occasionally caught a glimpse of a shiny stone. After identification, it turned out to be the largest blue diamond. The old man asked the craftsman to rough process the diamond, and the processed blue diamond was 1 12.5 carats. After the old man died, his three sons competed for diamonds. As a result, the diamond was confiscated by the patriarch and ordered to be inlaid on the forehead of the idol.

One night, a young man who couldn't resist the blue light of diamonds stole them. But only a few hours later, he was captured by the patron saint Brahman and beaten to death, becoming the first victim of the blue diamond. The blue diamond was re-inlaid on the idol's forehead.

/kloc-At the beginning of the 7th century, a French missionary killed two Brahmins with an axe and took the blue diamond for himself with his bloody hands. The missionary brought the blue diamond back to his hometown, but on a thunderstorm night, his throat was cut and the blue diamond disappeared.

Forty years later, the blue diamond fell into the hands of Jean Tavernier, a jeweler in Paris, who immediately sold it to King Louis XIV of France. A few years later, Joan Tavernier went to Russia to do business and was killed by a wild dog.

Louis XIV couldn't put it down. After thinking about it, I put the blue diamond on the scepter symbolizing kingship and took it off. His mother was named "French sapphire", but one day soon, one of his favorite grandchildren was inexplicably killed. Louis XIV died shortly after this blow.

After the death of Louis XIV, "French sapphire" fell into the hands of Princess Belle. She took the diamond from the scepter and hung it on a necklace as an ornament. 1792 On September 3rd, in an accident, Princess Belle was beaten to death by a group of civilians.

"French sapphire" changed from Princess Belle's pet to the treasure of Louis XVI and Queen Mary. But a storm in the French Revolution sent King Louis XVI and Queen Mary Anthony to the guillotine. "French sapphire" was stolen by the royal bodyguard Jacob Cerroti in this revolution.

When the French interim government counted the national treasury, it found that the "French sapphire" was missing, so it posted a notice: anyone who hides royal treasures will be sentenced to death. After watching it, the bodyguard Jacob Cerroti fidgeted all day, went insane and finally committed suicide.

"French sapphire" has brought its owner more bad luck than the wizard's curse, and people regard it as an ominous thing. Nevertheless, there are still many greedy eyes staring at it in the world, hoping to become its master one day.

The "French sapphire" was transferred from Crown Prince Ivan to Queen Gardelin I. The Queen wanted to set the diamond in the crown, so she ordered the "sapphire" to be sent to the Netherlands, where it was carefully processed by world-class craftsman Wilhelm Fowles. After careful carving by Wilhelm Fowles, the "French sapphire" was cut into what it is now, with attractive blue light shining on each side. After processing, the drilling weight is 44.4 carats. After the diamond was processed, the son of the diamond maker left without saying goodbye and took the diamond to London, England. The diamond maker who couldn't find a job committed suicide by taking poison to thank the queen. And his son later committed suicide in England, the cause of death is unknown.

Henry Phillips, a British jewelry collector, bought the diamond for $90,000 that morning by an anonymous person and named it "Hope". 1893, Henry Philip died suddenly. His nephew became the owner of "Hope" blue diamond. The owner of the diamond put it on display in the exhibition hall, and later it was said that he died.

At the beginning of this century, a businessman named Jacques Ciro bought "Hope" diamonds, but soon he committed suicide inexplicably.

The diamond fell into the hands of a Russian, who was assassinated and died soon.

Habibou Bay bought diamonds and sold them to Simon. It is reported that Habibou Bay and his family drowned in the sea near Gibraltar. Simon lost his whole family in a car accident.

The diamonds were transferred to Sultan Abdullah Hamid II of Turkey, and a princess was killed. Sultan himself was deposed by the Turkish Youth Party in 1909.

I hope the next owner of the blue diamond is the Washington millionaire Wolth McLean and his wife. Since the possession of this diamond, disasters have followed, and their sons and daughters have suffered misfortune one after another.

As a treasure of human art ~ the price is immeasurable!
