Peter the Great built a mysterious building in the East Palace in St Petersburg where he lived. All the jewels in the collection are kept in it, and the world calls it the diamond vault. After Peter the Great, Queen Catherine II was the most obsessed with jewelry collection. If every woman in the world loves diamonds, then the woman who loves diamonds the most is Catherine II. She loves diamonds, wears priceless diamond ornaments every day, and her patterns are often renovated. She has extremely high requirements for diamond cutting and inlay technology. The best diamond cutting expert in Russian history appeared in the period of Catherine II. There was once a court bodyguard who dared to praise the beauty of the queen's diamond ornaments and was promoted to the head of the bodyguard. Officials, large and small, regard providing diamonds as the most direct way to get promoted. A queen's birthday, as a result, more than half of the tens of thousands of birthday gifts received were diamonds. The queen's diamonds are not only inlaid as jewelry, but also everything she uses every day. She has a 17th century Bible with 30 17 diamonds on the silver cover.

With the continuous collection of several generations of royal families, Russia's diamond library has become the most concentrated place for precious diamonds, and there are only three world-class 10 diamonds. The most famous diamond is orlov, which is currently the third largest diamond in the world, weighing 189.62 carats. /kloc-At the beginning of the 0/7th century, a rough diamond weighing 309 carats was found in the diamond placer in Golconda, India. According to the will of the king of India at that time, a diamond processing expert planned to process it into a rose shape, but failed to do so, resulting in a lot of weight loss (only 189.62 carats). This wonderful diamond later became the eye of the Brahman statue in the Indian temple of Seringa.

1739, after India was captured by the Persian king, this diamond was decorated on the throne of the Persian king. Then the diamond was stolen and fell into the hands of an Armenian. 1767, Armenians deposited diamonds in a bank in Amsterdam. 1772, these diamonds were sold to Ivan, a Russian jeweler. Ivan sold the diamonds to the Count of orlov for 400,000 rubles on 1773. In the same year, Count orlov named this diamond "orlov" and presented it to Catherine II as a gift on the naming day. Later, the "orlov" was welded into a finely carved sterling silver base, which was embedded at the top of the Russian scepter to decorate the scepter of Catherine II. The legendary diamond ornaments make the scepter awe-inspiring, and "orlov" has become one of the most important collections in the diamond library. During World War II, Russia also lost a considerable number of treasures, including the Amber Hall, which is called "the first jewelry box in Tian Zi". In 17 1 1 year, King Frederik 1 of Prussia ordered the construction of the Amber Hall. The amber room is square and covers an area of about 200 square meters. * * * Use 6 tons of amber and decorate it with diamonds, emeralds and rubies. Its value is not only reflected in the amazing concentration of wealth, but also a masterpiece of baroque art. Five years later, Frederik 1's son, Emperor William I, gave the Amber Room to Peter the Great to celebrate Prussia's alliance with Russia, and Peter the Great put it in the diamond vault. /kloc-In the mid-8th century, Catherine II ordered craftsmen to decorate this hall, and the Amber Room became a magnificent hall and amber room. 1770 when the final renovation was completed, the hall was brightly lit, 565 candles lit up the whole hall, and the candlelight sprinkled on the jewelry was dazzling ... 194 1 autumn, German invaders occupied the palace of former Catherine II. Hitler ordered the Amber Hall to be demolished, packed in 27 crates and shipped back to Germany, and put the city of Witz, Crolle (now Kaliningrad) in. At 1943, the situation went downhill. The hall fell back into Soviet hands, and the Amber Hall was dismantled and boxed by the Germans and hidden in Teutonic Knight Castle and nearby air-raid shelter. 1in August, 944, the allied forces bombed the city of Witz, Crolle, and razed the Teutonic Knight Castle to the ground. Since then, the whereabouts of Amber Hall are unknown. Now countless treasure hunters are looking for the amber room, but there is still no news.
