Why are diamonds so expensive
The reason why diamonds are expensive is not only because they are scarce, but also because they are difficult to mine, costly, and complicated diamond processing procedures.
The reason why diamonds are called “the king of gems” by humans and become the most expensive gemstone species is because diamonds have high hardness, high abrasion resistance and chemical stability; strong luster, not easy to wear after processing, and can last The ground shines with diamond luster; and its refractive index is large (2.417), and the dispersion is strong (0.044, the strongest among natural colorless gems). when
The inherent charm of diamonds
As a gem, it must have three major elements of beauty, durability and rarity. Diamond is the only gem variety that combines the highest hardness, strong refractive index and high dispersion. It is incomparable to any other gem variety. Such a treasure amongst treasures, rare amongst treasures, should be the most expensive amongst the most precious.
Diamond culture has a long history
Since ancient times, diamonds have been regarded by humans as a symbol of power, majesty, status and wealth. Its indestructible, invincible, persevering, persevering and masculine qualities are the goals that mankind always pursues. It has potential and great cultural value.
Why are diamonds so expensive and how are diamonds formed
Exploring diamond deposits is difficult and costly
The search for a diamond deposit is not like the legendary one. You can find a diamond deposit if you accidentally fall. The search for diamond deposits often takes decades, even hundreds of years of hard work and labor, and it is costly. For example, the exploration of primary diamond deposits in Siberia, the former Soviet Union, began in 1913 and it took 18 years of hardships before being discovered; Botswana’s “Oula” primary deposits cost 32 million US dollars and were unearthed after 12 years of struggle; In recent years, the primary diamond deposits discovered in northwestern Canada have gone through the arduous efforts of generations of geologists and cost at least several hundred million U.S. dollars.
The number of diamond deposits is small, and the grade of gem-grade diamond deposits is low
The number of diamond deposits in the world, if compared with the number of iron, copper and gold deposits, can be said to be pitifully small, one of a few. Of the diamonds mined, only 20% are gem-quality on average, while the remaining 80% can only be used in industry. But the value of this 20% gem-grade diamond is 5 times that of 80% industrial diamond. The world’s annual output of diamonds is about 100 million carats, about 15 million carats for gem quality, and about 4 million carats (equivalent to 800 kilograms) of processed diamonds. Some rough statistics have found that to get 1 carat (0.2 grams) of polished diamonds, about 250 tons of ore need to be excavated.
