Diamond information and definitions:
This is a diamond with a weight of over 60 carats and of the best quality.
The diamond prices have stabilized again, here you will find a price index over several decades.
is the weight of the diamond measured according to a unit derived from the core of the baobab tree. Today a carat is defined as 0.2 grams.
is the clarity of the diamond from inclusions.
There are the purity levels IF, which is flawless and is sometimes also abbreviated to LC.
Then comes vvsi1 and vvsi2 these are very, very small inclusions that the expert can only see with great difficulty with a 10x magnifying glass.
Vsi1 and vsi2 denote inclusions that are very small and si1-3 inclusions that are small can only be recognized by the expert with a 10x magnifying glass.
Such inclusions can never be seen with the eye, because they are significantly smaller than 0.15 mm in their largest dimension.
Diamonds that have larger inclusions are piqué diamonds.
Here, the purity level Piqué 1 is defined in such a way that no inclusion may be larger than 0.5 mm and only from Piqué 2 you can see inclusions on closer inspection.
Locations: South Africa, Congo, Angola, Tanzania, Russia, Australia (2 million ct./year. New in Canada, old in Brazil. The largest ever found in 1905: Cullinan 1 Type IIb - Diamond South Africa, Premier Mine in Transvaal, weight 3106 ct. South Africa - until 1866 an unknown country for diamonds - but then the 15-year-old son of the farmer Erasmus Stephanus Jacobs rested from work under a tree on the Vaale River and saw something glint in the sun. He found a treasure in the form of the first African diamond and didn't know. He gave the stone to his sister, who sent it to the Dutchman Schalk van Niekerk, who sold it to the dealer Jack O'Reilly for a couple of pounds He sent it to the surgeon and hobby mineralogist Dr. W. Guybon Atherstone in Grahamstown. He immediately recognized the authenticity of the round, pebble-shaped rolled stone. O'Reilly's yellow diamond weighed 21.25 carats. Dr. Atherston sent the stone n to the colonial secretary in Cape Town, Richard Sonthey, who understood the scope of this find; because where a stone is found there must be several. The stone went to London, was recognized as genuine, but the experts classified the accompanying rocks for further discoveries as not suitable for diamond deposits: no kimberlite, too salty, the formation of the rocks cannot be compared with those in India and Brazil. The following year, several more diamonds were found near the Vaal and Oranje rivers. Now mineralogist James R. Gregory came, carried out test drilling and wrote: "I carried out a thorough investigation in the districts in which diamonds were allegedly found, but found no evidence to infer diamond discoveries or diamond-bearing deposits". Another misjudgment: Due to the geological conditions in this part of the country, it is impossible that diamonds could ever be found there! Secondary deposits were not included in the consideration. Everything would have seeped away, had it not been for the Griekwah herdsman named Swartbovi, who knew about a Boer (van Niekerk) who paid well for "special" pebbles. He asked for 500 sheep, 10 cows and a horse for his stone. Niekirk paid and rushed to Cape Town, where he fetched 11,200 pounds ($ 250,000) for the 83.5 ct diamond from the jeweler Gustav Lilienfeld. Lilienfeld called his new acquisition "Star of Africa" and had it grinded in London and sold to the Earl of Dudley for £ 30,000. The media made the source known all over the world and thousands of adventurers packed their belongings in order to set off for South Africa in 1869 to "river-dig". Geologists now know that all of the origins have one thing in common: Unfortunately, the topography does not provide any clues. In very different countries, such as China, Russia, Brazil, India and Arkansas, diamonds were hidden under a 1,400 m thick layer of sediments and lavas that are still present today near the craters in Botswana and Lesetho. The prospecting - and in 2 years the first town with 50,000 inhabitants after Lord Kimberley. At the confluence of the Vaale and Oranje rivers, the miners fanned out in all directions. They camped in corrugated iron huts and apart from meat there was nothing to eat. Fever and other illnesses caused many to repent. But the diamond rush was kindled. Within a very short time, five thousand soldiers of fortune were mining. Few knew rough diamonds and mistook them for pebble quartz. The so-called more valuable stones were smashed because it was mistakenly assumed that hammer blows would not damage the diamond. Sometimes there was a stone just below the surface in the soft tuff and the prospector could scrape it out. Normally, however, the yellow earth had to be removed and mixed with water. The sludge was then poured out and shaken through 3 sieves. Such vibrating troughs separated the larger from the small stones. Then they were spread out on a greased board. The worthless stones fell off, the diamonds got stuck. The yield was not productive enough for the many miners, and you didn't want to stand up to your knees in the water all the time, so you searched the area. They heard of a Vooruitzigt far-sighted farm where a single prospector found flawless diamonds. Organized diamond mining began on this farm in May 1871. The secondary deposit on the farm of Boer Johannes Nicholaas De Beer, whose son-in-law staked and sold 800 claims within a few weeks, was the NEW RUSH. De Beer had previously pursued agriculture and cattle breeding in peace, feared for his life and was no longer up to the new challenge. He sold the ranch for £ 6,300 and was sure to have received £ 6 million. In addition, another, even more productive premier mine was found 1.5 km away: the Kimberley Mine, where so many chlaimholders removed the dry earth that it soon became known as the BIG HOLE. The city grew to over 500 inhabitants on the edge of the Kalahari Desert, west of the city. The city was in dire need of an improvement in health, hardly any sanitation, a high mortality rate from poor medical care and common diseases such as bronchitis, pneumonia, tuberculosis, etc. But the city had to have a better name than New Rush: It was named after His Lordship , renamed the Colonial Minister to Kimberley on July 5, 1873, who also gave the name for the diamond-bearing rock: Kimberlite. The development of this city with the merger of the claim owners to form the De Beers dynasty under Harry Frederick Oppenheimer provides further material. Further deposits have since been developed in: In addition to the mines of Kimberley, the neighboring De Beers, Wesselton, Bulfontein and Dutoitspan. These are the so-called "big five", as well as Jagersfontein on the Orange Province and 3 km from Pretoria: Premier in Transvaal found by Sir Thomas Cullinan, 1902. Rhodesia (Zimbabwe), southern Zaire, 1908 near Lüderitz an der Atlantic coast as sea deposits, Liberia 50 km from Monrovia, western province on the border of Sierra Leone, Tanzania In 1939 the largest kimberlite chimney known in Africa was discovered there by Dr. J.T. Williamson, Canadian geologist found it at Mwadui, 140 km south of Lake Victoria, Angola, 1960 Postmasburg - the Finch mine discovered by A.T. Finchman, 1967 Botswana 200 km west of Francistown on the edge of the Kalahari desert, west of the Transvaal region to the Orange River Ghana, Namaqualand (sea deposits) The following sites are interesting in history: India knew diamonds as early as the 4th century. v. And historical diamonds were found, such as the Koh-i-Noor (Mountain of Light) in the river bed in 1304 with 103.93 ct now, after the regrinding. The mines in the Panna district in Madhya Pradesh state and the formerly famous Golconda in Haiderabad are practically insignificant today. Borneo from 600 diamonds were found here at Bandjarmasin in the secondary gravel, insignificant. Brazil In 1721 the first diamonds were found in Minas Gerais. 1759 in Bahia, Mato Grosso and Golas. They mostly occur in secondary deposits. The largest diamond found in Brazil, the "President Vargas" weighed 726 ct. It was found in 1938 in the San Antonio River, Coromandel Municipality, Minas Gerais, and in 1941 it was cut into 29 stones, the larger ones in an emerald cut. USA In 1849 the first diamond was found in California, further finds in Murfreesboro in Arkansas (only single diamond crystals) The largest diamond found here was found in 1924 and weighed 40.23 ct. A diamond weighing 23.75 ct was found in Virginia in 1955. Australia In 1851 diamonds were found in New South Wales, followed by others in 1872. They were secondary deposits. Occasionally some have also been discovered in Queensland, South Australia, Victoria, and Western Australia. In 1981, a new primary deposit was discovered by the Australians, which De Beers had searched for over 15 years and could not find. It is a very productive mine found 2200 km north of Perth at Smoke Creek, Argyl. The diamonds are mostly colored. From brown to yellow to the unique pink color. British Guiana In 1887 diamonds were found in river soaps on the north coast of South America. Venezuela in 1901 was found in the deposits of the Cuchivero River, about 450 km southeast of Caracas. Russia In 1829 the first diamond was found in the Urals. In 1949 a secondary, productive field was opened in Yakutia in eastern Siberia. Systematic prospecting led to the discovery of the first primary deposit in 1954, a kimberlite vent as in Africa. Since then, more mines have been discovered.
