The term “rough diamonds” applies to diamonds that are in their natural form, without being cut or polished. They would look more like a small lump of crystal than a brilliant shining diamond in a store. Diamonds in their natural state are found in shapes like a cube, an octahedron, or dodechedron. Some diamonds have even been found in the shape of a hexoctahedron, however, they are most often found in an octahedron shape. Diamonds also come in a shape known as a macle. These shapes can best be described as two pyramids that have been glued together. They are extremely difficult to cut. Most rough diamonds in the shape of a cube are unlikely to be satisfactory jewelry quality. You can not see through a rough diamond and they will not have the same shine when held to light. If you were to come across a natural diamond, you probably not recognize it, unless you had seen a picture for reference. Some of these rough diamonds can be found at your local AZ diamond pawn store.
Diamonds are believed to have been objects of trade as far as back fourth century B.C. Many diamonds in these days were found in India, and were prized by Europeans who purchased or traded for them along the Silk Road. However, India’s supplies dwindled, and Brazil rose as a leader in the diamond trade. Diamonds were used in a number of ways, such as a cutting tool. The stones were found in riverbeds, and individuals of noble birth love to wear them. They found their use in battle as decoration on breast plates and as talismans to ward off bad spirits. Eventually they would be used by royalty to show their wealth with diamond-studded crowns, tiaras and pendants.
In 1866, Dutch teenager Erasmus Jacobs uncovered a 21.25-carat diamond in the banks of the Orange River. He was looking for pretty stones to play with, and he gave the stone to a neighbor, who had it confirmed by a mineralogist as a diamond; the diamond was named Eureka. The diamond is on display today at the Kimberley Mine Museum in South Africa. Later diamonds were found away from the river in volcanic pipes. The biggest diamond mine was named “The Kimberly Mine.” The diamond race in South Africa was on, and though many profited from the practice, De Beers had control of 90% of the world’s rough diamond mining by 1900.
Canada’s Northwest Territories entered the diamond rush in the 1990’s, when a miner found the first diamond that could be confirmed after many unsubstantiated reports throughout history had occurred. The Ektaki mine opened in 1998 about 200 miles northeast of the town of Yellowknife and produces around $600 million in diamonds annually. With many concerned about “conflict diamonds,” Canada provides lets jewelers buy diamonds without worrying about human rights violations.
Diamonds have been found in all sizes and weights. The biggest rough diamond ever located is the Cullinan Diamond, named after the mine where it was found. It weighed 1 ⅓ lb or 3,106.75 carats. It was cut into nine pieces, and several of the pieces were used in royal items such as the Imperial State Crown of Elizabeth II. The second diamond ever found was named the Excelsior diamond and it weighed 995.20 carats.
