Why Diamond Stones It Very Hard?
when you take a piece of make thick paint material and want to make it into an ape, then what would you do? you will hit and pressure. the more you squeeze and getting in the press, then the harder too. any diamond is shaped in a way that is by nature, a million years ago when Earth is still at the beginning of cooling stage, at that time in the ground there are a substantial number of rocks in liquid state due to the heat, then these objects was subjected to great heat and pressure. carbon that is formed by the incredible pressure that we call with the diamond.

diamond is the hardest material in the area of this nature we are known for, but it is not easy to measure exactly how hard a diamond material. one way to test the level of violence in the diamond stone is to us test of scratches, that scrape the ingredients diamond with other hard objects.

in 1820, an expert named Mohs make a kind scales for measuring and drawing up a list-sort by the rigors of nature of a mineral. the results obtained are based on such test, i.e. tests scratches. according to the list in the arrange by order of the rigors of mineral materials, ranging from the most soft to the hardest of which is as follows :
1. talk
2. cast
3.calcite
4. fluorite
5. afatit
6. feldspar
7. the quart
8. topaz
9. corundum
10. diamonds
but the results of these measurements is in comparison to each other, for example, it was found that despite the fact it is at the level of the corundum to 9 in the hardness minerals, and diamonds in order to 10, but the difference between the two was different in the hard is huge, compared to the difference between 9 and 1 on the scales, so diamond won the hardest objects in the world, there is no comparison.
because diamond is so hard, and then arises the question, how do people get cut and give shape to the diamond/the only objects that can be sliced or cut diamond is just another piece of the diamond, which is used by the sharpener no other diamond is the kind a chainsaw on its perimeter lined with diamond powder.
in fact the wheel grinders and cutters made of diamonds are widely used in the industry with a variety of ways. for example, among others, to scrape the lens, to give form to a wide range of utensils made of copper, brass and other metal materials, also used to slice up the glass, this is now more than 80 percent of the total number of diamonds produced people and is used for industry.
