Investment in old diamonds or new diamond difference and explained.
A diamond is a faceted natural diamond having a certain number of polished facets. The history of diamonds is closely related to the history of diamonds. However, all researchers agree that for many centuries India was the "monopolist" in diamond mining. It was Indian craftsmen who first learned how to cut diamonds, turning them into diamonds. From the very beginning of their fame, these beautiful stones were given religious significance. The statues of mysterious Hindu gods were decorated with diamonds, the priests owned the reserves of precious stones. Diamonds got to Europe through a few travelers and merchants who overcame the most challenging path. But these diamonds were not like modern ones. At best, the craftsmen were able to polish the diamond along the natural edges. The stone caused supernatural horror with its hardness, but it was scarce and valued less than, say, a ruby or a sapphire. Perhaps it is precise because no one has ever seen the magnificent play of the diamond.
India was the world's only source of diamonds until the 18th century. Then the "diamond rush" began to cover other countries and continents. In 1725, a diamond deposit was found in Brazil. For more than a century, the center of world production of these stones shifted to South America. Brazilian deposits were discovered by a Catholic priest who had lived in India for a long time and therefore had an idea about diamonds and places where they could be found. And in 1869, a specific South African farmer innocently came to the tavern with a bottle of "flints," which he picked out of curiosity from the clay bricks of his own house. The "flints" turned out to be diamonds! Thus began a new era of diamond mining. And today, the words "diamond" and "diamond" are associated all over the world with the company "De Beers," which "grew up" in the South African mines. The founder of the De Beers Diamond Corporation was Cecil Rhodes.
The world's most giant crystal weighing 3,106 carats was mined in 1905 in South Africa and named "Cullinan." It was so big (10 x 6 x 5 cm) that at first, no one even believed that it was a diamond. The Transvaal government paid 150 thousand pounds for it. In second place is "Excelsior" (995 carats), also mined in South Africa in 1893. The stone of the third magnitude in 969 carats – the "Star of Sierra Leone" was found in 1972 and purchased at auction by Harry Winston. The price remained unknown.
In Russia, the first diamond was found in 1949 in the Vilyu River basin. And in August 1954, Leningrad geologist Larisa Popugaeva, who bravely traveled through the remote taiga with only one worker, discovered in Yakutia the first indigenous diamond deposit in the USSR - the famous kimberlite pipe "Zarnitsa." In just forty years of geological research, more than 800 kimberlite pipes have been discovered in Yakutia.
Although diamond has been known as a gemstone for more than two millennia. The first attempt to process it to enhance its luster was made only in the 14th century. At the same time, processing was limited only to polishing its flat faces.
The first diamond was made in 1454 by Louis de Berkham, the court jeweler of the Duke of Burgundy Charles the Bold. When the warlike duke saw the diamonds, he immediately found a use for them on the battlefields. He ordered them to decorate his armor with them so that the brilliance of the precious stones would dazzle and terrify enemies. Other crowned warriors began to follow the example of Charles the Bold.
The written certificate of diamond cutting is dated 1463.
As a result of the earliest experiments, such a form as a "diamond table" appeared. The peculiarity of this cut is that the flat face is on top, where the upper part of the crystal is sawn and polished. The rest of the crystal is left unchanged.
The "rose" cut originated in the 16th century. Usually, the stone was obtained with a flat base and faced radiating from the center in an amount multiple of six, which gave the impression of a rosebud opening. Rocks of this cut can be rounded, pear-shaped, and oval. The "rose" cut is still used for small and flat diamonds, but diamonds cut with "rose" often can be found in antique products. "Roses" are valued much lower than diamonds since they do not have the brilliance and play characteristic of the latter.
At the end of the 17th century, Vincentio Peruzzi from Venice invented a diamond cut with 58 facets. 33 in the crown above the girdle and 25 in the pavilion. And since then, cut diamonds have been called diamonds of the old miner's cut. They are characterized by a shape close to a square or a "pillow." The platform at such stones is minimal. The palette is extensive and easily visible from above, resembling an opening.
The stones of the old European cut appeared in the middle of the 19th century. They are similar to the rocks of the old miner's amount but more rounded and have 58 facets. The top of them is less high than the stones of the old miner's cut, the palette is smaller. Such diamonds can be found in jewelry made up to 1930.
Most of the diamonds of the old European cut have a yellowish color. In the 1870s - the diamond rush in South Africa, diamonds of these shades were mainly mined.
Vintage diamonds can be very spectacular. The strong play of some of them is simply fascinating.
Usually, the stones of old facets are evaluated by comparing them with rocks of modern cut. Their value is determined by assessing the stone's color, purity, and weight, which could have turned out if they were re-painted in a modern way. We do not recommend you reshape antique diamonds; if they are installed in the original frames, this can harm the integrity of the product and reduce its cost. However, in some cases, an unattractive old-cut stone can benefit from re-cutting. Although it will lose weight, it will become more expensive in value.
Around 1900, a transitional form of cutting appeared. In 1919, diamond cutter Marcel Tolkowski developed an optimal combination of angles that allows light to penetrate the stone and be reflected. Top play is created with the most minor loss of luster. The Tolkowski cut is the basis of the modern ideal for new diamond cut.
