Exploration diamond drilling differs from other geological drilling (such as Reverse Circulation (RC) Drilling [3]) in that a solid core is extracted from depth, for examination on the surface. The key technology of the diamond drill is the actual diamond bit itself. [4] It is composed of industrial diamonds set into a soft metallic matrix.
As of 2014 about 6,400 kimberlite pipes are known on Earth including about 900 that have been found to contain diamonds, with mining of diamonds occurring at about 30 pipes. [ 25 ] The discovery of diamond-rich kimberlite pipes in northern Canada during the early 1990s serves as a prime example of how challenging these deposits can be to locate ...

Laboratory work in mineral physics require high pressure measurements. The most common tool is a diamond anvil cell, which uses diamonds to put a small sample under pressure that can approach the conditions in the Earth's interior.
Big price tags and diamond jewelry typically go hand in hand. Engagement rings can easily set you back a few thousand dollars, especially if you are looking for the highest quality in cut, clarity ...
