With lots of time, diamonds will be found. They are normally found at volcanoes that erupts kimberlitic eruptions. A major known site is at Mount St. Helens. (Hart p. 24).
The process of searching for diamonds are split into two occurrences. The primary occurrence is a process in which diamonds are extracted. It can be extracted through open-cast mining which is also known as pipe-extraction, or underground mining. Open cast mining, pipe-extraction, and underground mining is a basic process in which people go to the volcanic areas and mine diamonds. Because diamonds are formed underground, weathered pipes end up having remains of rocks stuck to the side of these pipes. These rocks that are extracted in the primary occurrences are known as Kimberlites. The secondary occurrence of diamonds is a basic process in which diamonds are recovered. Since earth is surrounded by water, most volcanic areas are close to rivers and lakes. Weathered pipes allows these diamonds to be dispersed by rivers and glaciers. It gets washed along coastlines and diamonds are recovered. This secondary process is known as the "Alluvial" process. Alluvial is basically the recovery of diamonds. (Schumann p. 55).
Diamonds are also known as gemstones. They come in many different shapes, size, and color. The size and unit of a diamond is referred to as "carat." Diamonds differentiate from one another by the color and clarity of that precise diamond. Two diamonds can be about the same size and weight in carat, but depending on the color and clarity of that diamond, one of them could be worth so much more. The most valuable diamonds are the ones that were formed completely colorless and contains no trace of impurity, along with how well they were crafted by hand. Emeralds, rubies, and sapphires are also expensive because of the beauty given off from its color. (Post p. 13) .
The surface of a diamond is called "blemishes," while the internal part is known as the "inclusion.
