Are most most diamonds formed inside kimberlite?
All diamonds are formed from carbon. Kimberlite and diamonds are both erupted to the earth's surface via volcanic pipes. Kimberlite is an indicator mineral, increasing odds for geologists that a volcanic pipe includes diamonds: not all pipes erupt diamonds with kimberlite. Kimberlite can be considered a 'neighbor' or 'kin' of diamond, but not a source.
Are most diamonds mined directly from Kimberlite?
Kimberlite is an indicator mineral, formed deep within the earth's mantle where diamonds are also formed. Often, they are found together, but not always. Kimberlite is not diamond: they are different minerals.
Where do brown diamonds come from?
Brown diamonds come from the earth just like all other diamonds. Brown diamonds come from every mine in the world, and the most profitable mine that produces them is called the Argyle mine in Australia. Notable brown diamonds, however have come from Brazil and from Africa.
Where chocolate diamonds come from?
Brown diamonds are the most common of coloured diamonds. 'Chocolate' is simply one of the words used to describe a specific shade of brown diamond. All diamonds are formed deep within the earth's mantle.
What is the average age of most diamonds on Earth?
Most diamonds are estimated to be between 1 billion to 3.3 billion years old. These diamonds are formed deep within the Earth's mantle under high pressure and temperature conditions over billions of years.
Can a diamond be created in any rock?
No. Diamonds are an allotrope of carbon formed deep within the earth's mantle under extremes of high pressure and temperatures. This unique combination is what forms diamonds over millions of years.
What are the compounds in diamond?
Natural gemstone diamonds are formed from pure carbon. Often trace minerals are included, and in 'white' diamonds, the trace mineral is often nitrogen, which gives the gemstone a yellow tint. A flawless gemstone diamond may contain another element such as boron, or have been formed with a molecular structure that affects its colour, and these gemstones are the most valuable. Industrial diamonds are formed with visible inclusions of other minerals, which are not often classified. This is because industrial diamonds -- about 80% of all diamonds mined -- have relatively low value as compared to gemstone diamonds.
Is there diamond in a coal mine?
It is possible to find diamonds in coal mines, as diamonds are formed from carbon under high pressure and temperature conditions similar to those found in coal mines. However, finding diamonds in a coal mine is rare, as most diamonds are formed deep within the Earth's mantle and brought to the surface through volcanic activity.
Why do you find diamonds in little pieces when they are the hardest material on earth?
Diamonds are formed deep within the earth's mantle under extreme high pressure and temperature. Most diamonds -- 80% -- are industrial diamonds, the tiny pieces you describe. Gem-quality diamonds are more rare -- the remaining 20% -- and large, gem-quality diamonds are most rare. Pea-size or smaller is the most common size for diamond stones. As to why -- the answer is in the mysteries of geology and its formation technologies, which are generally unpredictable and always random.
Where are some of the most diamonds?
Truly, diamonds are everywhere. Above ground, you can find the 20% of mined diamonds as gemstones in jewelery stores and being worn by humans. The remaining 80% of mined diamonds -- industrial diamonds -- are in use as enhancements to tools. As well, since diamonds are formed below the earth's surface, there may be many more unmined diamonds there.
Where does most of the ore come from in diamonds?
it comes from the earth...the earth made diamonds,rubys and other special rocks
How much diamonds are on earth?
There is an estimated total of about 1,200,000,000,000 carats of diamonds on Earth, which is roughly equivalent to 240,000 metric tons. Most of these diamonds are located deep within the Earth's mantle and are not easily accessible.
