One way to turn graphite into diamond is by applying pressure. However, since graphite is the most stable form of carbon under normal conditions, it takes approximately 150,000 times the atmospheric pressure at the Earth's surface to do so. Now, an alternative way that works on the nanoscale is within .And Diamond is formed by carbon . So these have same properties.
