The oldest diamond in the past and present of jewellery

A few years ago, a company in the United States announced an amazing news: 3 to 10 缕 Beethoven's hair will be used to make three 0.5-carat to 1-carat diamonds. If this idea is realized, Beethoven’s ability to be alive will no longer be just his music.

Choosing hair to make diamonds is because it contains a single element that forms diamonds - carbon. Among the many dazzling gemstones, only diamonds are the symbol of eternity. Its physical and chemical properties are very stable and can be stored permanently.

The age of diamonds is unimaginable. According to scientists, the youngest diamonds are also 990 million years old, and the oldest diamonds were formed 3.3 billion years ago. Imagine that the earth hundreds of millions of years ago may have only microbial activity. In the depth of the earth's crust, about 200 kilometers deep, a group of carbon elements gather together to form crystals at a temperature of more than 1000 degrees Celsius and as high as 40,000 to 60,000 atmospheres. As the crustal movement arches out the surface.

Legend has it that about 3,000 years ago, an ancient Dravidian farmed on the central plateau of India, where the sun was roasting. Suddenly, he was attracted by a glistening little round stone, this crystal clear little thing, mysterious, It is fascinating and beautiful, and it has a seductive atmosphere. It is the diamond that people first saw.

Not long after, the clever Gudrawe people discovered the hard quality of diamonds. From the inscriptions they left in the cave, the tip of the tool was set with diamonds to cut other things. The Mohs hardness of a diamond (referring to the ability of a gemstone to resist external force scoring) is 10, with the highest index in the gemstone. Before the beauty of diamonds has yet to be fully revealed, its hard and fire resistance has a mysterious power in people's eyes.

At first, people thought that diamonds were indestructible. An ancient Roman scholar described this: When people put a diamond on an anvil and hit it with a hammer, "it will produce a huge counterattack, causing both the hammer and the anvil to split into pieces." This statement lasted for a long time, until 1476, when a group of soldiers hammered a diamond with a hammer to verify the true and false, the result was a diamond.

The unique quality has cast a mysterious color on the diamond. The ancient Indian book about the gemstone, "The Buddha", writes that the person wearing the diamond can be protected from snakes, fire, poison, disease, and theft. And the evil of the magic. What is even more peculiar is that in the eyes of ancient and medieval philosophers, diamonds still have life, "also divided into men and women", able to freely multiply, "giving small diamonds." Even Plato thinks so.

Although the hardness of a diamond has been known and used early, its surface is always sticky and thick, and only occasionally flashes a dazzling light. After entering the 17th century, the "rose-cut" and "bright-cut" techniques that have emerged have made the beauty of the diamonds hidden inside. The former makes the diamond "like a blooming rose", which can cut the diamond into 58 faces, releasing a dazzling light and unpredictable colors. At this time, the diamonds became hot, and the squandering of the princes and nobles reached an unprecedented level. The diamonds on Louis XIV's black dress are worth up to 12 million pounds. Louis XV intends to give a lover a necklace consisting of 647 flawless white diamonds with a total weight of 2,880 carats.

Carat is the weight unit of gemstones. It is derived from the seeds of the carob tree in the Mediterranean region - rice beans, which weigh more than 200 mg. 1 carat is equal to 0.2 grams or 200 milligrams.

It has been estimated that about one karat of diamonds can be produced for every 250 tons of ore excavated. Known as the "world's best" Cullinan diamond, the original stone weighs 3,106 carats, three skilled craftsmen, working 14 hours a day, it took 8 months to divide it into 4 large diamonds and 101 small diamonds. This rare and rare is the preciousness of diamonds.

For a long time, diamonds have been regarded as a symbol of power, majesty, status and wealth, and have nothing to do with love. In 1477, Austrian Maximilian I wore a diamond-encrusted ring on the princess's hand when she was married to Princess Mary of France. Since then, diamonds and marriage have joined hands and become the iconic gift that the world’s men hope to “catch the beauty back”.

"Diamonds are long-lasting, and one is forever." Men wish, women are happy. May marriage be like this.
