A Russian diamond company has announced that it has discovered a diamond weighing about 158 ​​carats in the Russian Republic of Yakutia. Earlier, news of the existence of huge reserves of diamonds (diamonds) in the eastern part of Russia was shocking the world. According to the reporter, Russia is one of the top five diamond producing countries in the world, but many people are not clear about it because of its late development. .jpg)
For more than half a century, Russian diamonds have come mainly from the Mirne mine in Yakutia, which has brought at least $17 billion in wealth to Russia. In 2007 alone, Russian diamonds reached 1.35 billion U.S. dollars, 98% of which were exported to Belgium and Israel. Russia's Yakutia is located in eastern Siberia, covering an area of ​​more than 3.1 million square kilometers, accounting for one-fifth of Russia's area. It has been Russia's largest diamond producing area, accounting for 90% of Russia's reserves (about 1 billion carats) and 98% of production. , accounting for 28% of the world's total production. Yakutia is the coldest region in Russia with a population of about 100,000. It is said that before the Soviet geologists and industrial diamond mining companies came to Yakutia, the indigenous people were not interested in the glistening gemstones, and even felt fear. They thought that it was "the eyes of God" and did not dare to shake. In the past, Yakutia’s diamond mining has been carried out in secret and has been closed for 11 years for safety and market reasons. Recently, Russia changed its mindset and used quality diamonds as a beautiful business card for Yakut. In August of this year, the “Yakut Diamond Week†tourism project was held for the first time. The organizers hope to make it a unique tourism brand in the world, and invited more than 70 journalists from China, Japan, the United States, Britain and France. The Yakut proudly claims that Yakutia is "the only region on the planet that mines diamonds and processes them at the same time." Participants can stand on the edge of the Mirne mine and see this spectacular crater 525 meters deep and 1,300 meters in diameter. At Yakutia's most rigorous diamond grading center, managers tell people how to evaluate diamonds with 8,000 indicators. In the diamond library, one can appreciate 350 carats of diamond and platinum ore. Visitors can also visit the finely crafted workshops, artisan rooms and diamond exhibitions, and wear the purchased accessories to the ball at night. The reporter saw a lot of unprocessed Yakut chunk diamonds at the Moscow Kremlin Treasure Hall. At the jewellery fair held in Moscow not long ago, the reporter visited the Yakut gem counter. Although the price of diamonds varies according to processing and quality, the diamonds processed at the local diamond cutting factory are moderately priced and popular. Russia's gemstones are very rich, and many cities have their own ore museums and regularly hold gemstone exhibitions. For example, the Ural Mountains are known as the “gem belts†of Russia, which contain a variety of beautiful gems. The city of Yekaterinburg holds gemstone exhibitions every month. According to the reporter, the newly announced Siberian diamond mine Bopige diamond mine is located in the Krasnoyar region near the Yakut border. The formation of Poppy's diamond is different from that of Yakut diamond. Experts call it "impact diamond" formed by celestial bodies such as meteors striking existing diamond mines. It is said to be a very unique diamond with a higher hardness than ordinary diamonds and is highly sought after in the high-precision scientific instrument manufacturing and industrial markets.

A wedge-shaped brass gate is lowered into a machined slot to close the valve. They should either be completely open or completely closed. Water flowing through a partially open gate valve wears away the metal and causes the valve to fail over time.
