- The diamonds can help the scientists find the rough date in scientific field.
- The diamonds are formed by the earth, and the scientists found most of diamonds are formed by the Volcano eruption.  
- The scientists want to know if they can find the rough date of the diamonds. The movement of plates and the weather conditions both effect the formation of the diamonds. The deep geography of earth may hide a lot diamonds, but they are buried 200meter below the earth, since it's cool there. The temperature was very hot on earth at first, then it's cooled down, this can cause the big pieces of rocks? formed. Therefore, it's necessary to study the deep geography to estimate the rough date of diamonds.
- Some inclusion of diamonds can be seen easily by eyes, some are not. For the flawness of the diamonds, the scientist Shirey said that he cannot control over these diamonds, they have to be either sold out or donate.
- Although people say the diamonds could help the scientists with their studies, it's not totally true. Richardson and other scientists have to spend more than 3 years on more than 100 diamonds for their studies, it's not worthy.
- Some diamonds are formed very different from others, Shirey found that the diamonds are formed very different in Zimbabwe as those found in Australia. These diamonds are mantled by the earth, so they need tools to study more on deep- geography in order to get better results.
