Diamonds are created by the movement of fluid in a redox reaction with methane. Scientists have discovered a new way to make diamonds. Recent studies have shown that water could make diamonds as the ph level drops. This takes place really, really deep in the earth. The lead researcher said that "diamond formation in the deep Earth, the very deep Earth, may be a more common process than we thought." It is estimated to be around 90 to 120 miles below earth's surface. At that location there is extreme pressure and the temperature is 1,600 to 2,000 degrees fahrenheit. These diamonds are formed really deep in the earth while the diamonds we use for jewelry are brought to the surface by minor eruptions. The diamonds are microscopic and wouldn't have the same value as the ones we have. This research shows that diamonds are more common than we were led to believe.
The information in this article affects humanity because the diamonds are so microscopic that they would have no purpose for jewelry. Before I read this article I thought they found more large diamonds and the value would go down as well as the price, but when I read that they were microscopic, I knew it was hopeless. But all hope for these diamonds is not lost. Diamonds are the hardest naturally occurring substance in the world. On Moh’s hardness scale the diamond has a value of ten. Because the diamond is so hard and we have a new way it can be produced, we may have more material to put it on the end of drill bits and machinery that could drill through rock. For example, these drills are being used to drill a new subway tunnel in New York City which would benefit humanity, and help the morning commute.
This article was lacking specific detail regarding exactly where under the earth you would be able to find these microscopic diamonds. It would also be nice to conduct an experiment to try and match what their research says. After they analyze the results it would be helpful to include pictures of the final product because the article was lacking pictures. A comparison to what was made on the earth to what was made in a lab would also be beneficial on the reader's behalf. I'm more curious about if it's possible to find bigger diamonds in other locations on earth.

Francesca’s review of the article “Diamonds may not be as rare as once thought”, was well thought out and informative. While summarizing, Francesca included a quote she pulled directly from the article to help support her statement. I really appreciated her ability to refer back to the article.She presented her information very specifically but made sure to include just the basics. In her first paragraph, Francesca alluded the distance from the earth’s core with specific milage. Francesca consistently compared the information of diamonds found in the article with our known knowledge of diamonds. I think it helped us to compare what we knew to new information.
I enjoyed reading Francesca’s article because it provided me with new understandings of diamonds. I was very interested to learn that diamonds were created due to the pressure and temperature located underneath the Earth’s surface. I wasn’t aware of diamonds creation. I was also interested to learn that diamonds were used for subway tunnels. I mostly associated diamonds with jewelry. It was interesting to know that they have other purposes as well that actually help our lives.
While Francesa’s review was very informative there was an aspect that I wish she would have focused on. I discussed Francesca’s ability to be straight-forward and specific earlier. Unfortunately while Francesca did do well with those areas, she failed to include depictions of the events she was portraying. For example, when discussing that water helps make diamonds, it would have been a good use of knowledge to inform us how exactly that process happens. However, overall Francesca’s review was an informative and interesting read.
