Industrial diamonds are formed at the same time and in the same places as gem-quality diamonds. Industrial diamonds represent about 80% of all diamonds mined.
Industrial diamonds make up about 80% of all diamonds mined. As well, lab-created diamonds are mostly used for industrial purposes.
No, not in the current sense of the word. However, because diamonds are formed deep within the earth's mantel, new diamonds are probably being formed now. And it will take millions of years for those stones to be completely formed and erupt to the earth's surface where they can be discovered.
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.
Diamonds are formed deep within the Earth's mantle -- under extreme pressure and intense high heat. They are erupted to the Earth's surface through volcanic pipes. As well, there are man-made diamonds formed in laboratories.
A geologist would differentiate between a natural diamond -- formed by a geological process, and a synthetic diamond -- formed by a man-made process. Both diamonds are 'real diamonds'. Read more about synthetic diamonds, below.
Diamonds are formed from carbon, with the inclusion of trace minerals -- in gemstone diamonds. Only about 20% of all diamonds mined are gemstones. Industrial diamonds are also formed from carbon, but their structure is not as consistent as those found in gemstones.
Industrial diamonds come from diamond mines, in fact about 75% of all diamonds mined are industrial diamonds.
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.
You may be thinking of gem-quality and industrial diamonds. About 80% of all diamonds mined are industrial diamonds.
You may be thinking of gemstones and industrial diamonds. Gemstones represent about 20% of all diamonds mined, and the remainder is industrial diamonds.
These diamonds are industrial diamonds. About 80% of all diamonds mined are classified as industrial diamonds, leaving only about 20% to be graded as gemstones.
Genuine (natural) diamonds are formed deep within the earth's mantle, erupted to the surface through volcanic pipes and mined or gathered. Genuine (man-made) diamonds are formed in laboratories that attempt to mimic the conditions deep within the earth -- extreme high pressure and ultra high temperature -- and are manufactured over time. About 80% of all diamonds mined are industrial diamonds. Raw gem-quality diamonds are cut and polished into jewels. All diamonds are formed from carbon.
Diamonds are formed from carbon.
Raw diamonds are found in the earth; cut and polished diamonds are available in jewelery stores; industrial diamonds can be purchased from an industrial diamond broker.
The most common use of diamonds is for industrial tools, because industrial diamonds are the most common diamonds.
Industrial diamonds can appear cloudy and gray, because of their flaws and inclusions.
Diamonds formed from carbon in the lab, are diamonds formed from the mineral carbon.
