Diamonds are a source of attraction every human over thousands of years as a diamond has its own unique, shining and beautiful. Moreover, diamonds also conducts heat better than any other mineral. But where and how did the diamond formed? On this occasion, we will discuss the history or origin of the formation of diamonds on earth. However, nowadays people know that the diamond originated from the minerals in the world but they do not know which minerals can form a diamond. Diamond is the hardest
Diamonds are supposed to be symbols of love, and commitment, and joyful new beginnings, but for many people in diamond rich countries, these sparkling stones are more a curse than a blessing. Too often, the world’s diamond mines produce not only diamonds, but also civil wars, violence, worker exploitation, environmental degradation, and unspeakable human suffering; these diamonds are commonly referred to as “conflict diamonds” or “blood diamonds”. The negative effects of diamond mining have been
diamond crystals. When volcanic eruptions occur, magma carries the diamonds up to the surface of the earth. Kimberlite lavas carrying diamonds erupt at anywhere between 10 and 30 km/hour and increase their velocity to several hundred km/hour within the last few kilometers. (Pough, 44) At the surface, this lava cools and turns into Kimberlite rock. That is why diamonds are often found in kimberlite, a volcanic rock, which is often much younger than the diamonds themselves. All diamonds that are around
1.0 Introduction Historically, most of earliest diamonds were found in India where the first diamond mine in the world were developed (Edward and Hausel 2002). Today, diamond deposits are found in some locations as different situations. For instance, diamonds have been found and mined in southern Africa and the largest deposits are currently in Siberia (Yelisseyev et al., 2013). However, the largest diamond mine in the world is at Argyle in northern Western Australia that produces 25 million carats

The primary deposits often consist of diamond-bearing “pipes” of volcanic rock called kimberlite.

But, the final destination of a diamond is in the form of a ring- promising a lifelong commitment in the first world tainted
website “at one time, about 2/3 of Colorado was covered by [extrusive] rocks but much has eroded” (“Volcanic rocks,” 2013). Today, Colorado is home to many different types of intrusive igneous rocks, such as: alkalic complexes, batholiths, dikes, kimberlite diatremes, plugs, sills, and stocks. If you are looking for metamorphic rocks in Colorado, you will certainly find gneiss, schist, amphibolite, and quartzite. Theses rocks have been formed by both contact metamorphism and regional metamorphism
Diamonds can be created through both geologic forces and man-made processes. However they are made diamonds have many uses. In the first part of this essay we will look at the geologic forces involved in the making of a diamond. Next we will examine the man-made processes. In closing we will take a brief look at the many uses of diamonds. As we begin to look at how diamonds are formed it’s important to understand a little about the composition.
