The most essential component of the global jewelry market is the diamond and diamond market.
Today, rough diamonds are mined in Angola, Sierra Leone, Guinea, Australia, Tanzania, Zaire, Namibia, Botswana, South Africa, and Russia.
The sale of rough diamonds in the cutting industry is carried out through a network of diamond dealers. Most of the unsorted diamonds (about 50% of the value of world production) are sent to London through the channels of the De Beers Corporation. They are resold by the Central Sales Organization to several trusted wholesalers on websites. Wholesale diamond sales (sites) are held 10 times a year in London, Johannesburg, Lucerne. A standard wholesale batch of diamonds contains at least 100 thousand carats for a total amount of at least $ 1 million. At the same time, De Beers satisfies customer requests by 50 - 70%.
The world prices for jewelry diamonds are the sales prices of diamond products on sites in London and on diamond exchanges in Antwerp (Belgium) and Tel Aviv (Israel).
Until recently, the process of forming market prices for diamonds was not disclosed. It is only known that in comparison with the initial cost of rough diamonds, the price of diamonds in the wholesale sector increases almost 4 times, and in retail trade by 6 times.
Currently, the largest diamond production centers are Bombay (India), Ramat Gan (Israel), New York (USA), Moscow, Smolensk (Russia), Antwerp (Belgium).
