From Wikipedia:
"Diamonds are thought to have been first recognized and mined in India, where significant alluvial deposits of the stone could be found many centuries ago along the rivers Penner, Krishna and Godavari. Diamonds have been known in India for at least 3,000 years but most likely 6,000 years."
(An alluvial deposit is formed when water flows over the volcanic pipe that erupts diamonds to the surface of the earth and tumbles the stones into the riverbed.)

How do jewelers get the diamonds?
Diamonds can be cut with a diamond bladed saw, or with a laser, or they can be cleaved with a hammer and chisel.

What is an origin of an earthquake called?
The origin of an earthquake is called the epicenter.
Are there diamonds in volcanic tubes?
Only in some. Most diamond mines are in or near formations called Kimberlite Pipes, which form as a result of a rather unusual type of volcanic acvtivty that has not beem witnessed in human history. These volcanoes do not form the diamonds, but rather bring the diamonds up from great depths.
How far under the Earth's crust do diamonds form?
About 100 miles
Is the origin of diamonds coal?
No. The origin of diamond is carbon.
Are Haitian diamonds real or fake?
Regardless of their origin, a gemologist can tell you wheter or not a diamond is a diamond or an immitation. The country of origin is not a guarantee of anything, except the country of origin.
Is the origin of diamonds rock or coal?
The origin of diamonds is rock, specifically kimberlite and lamproite volcanic rocks that form deep within the Earth's mantle. Coal is a completely different type of sedimentary rock formed from plant material.
What is the possible origin of graphite?
Graphite, coal and diamonds are all thought to be products of the decay and compression of vegetable matter from millions of years ago. Diamonds progress from coal.
Are African diamonds inexpensive?
Every gem-quality diamond is valued according to its cut, colour, clarity and carat weight, regardless of its continent of origin. Some of the largest and clearest diamonds, including some of astonishing vivid colours come from Africa. These are the most expensive of diamonds. Examples are the Cullinan and the Blue Moon diamonds.
Do diamonds have a DNA?
DNA is a biological phenomenon visible through generations of reproduction. Diamonds have no generational cycle. Some diamonds, do, however, contain trace minerals that can be good indicators of their place of origin and discovery on the planet.
How do diamonds made in a lab compare to ones mined from the earth?
Lab-created diamonds have the same physical, chemical, and optical properties as mined diamonds. Both types are durable and can be used in jewelry. The main difference is the origin: lab-created diamonds are made in controlled environments, while mined diamonds are formed naturally deep within the Earth.
Is the country of origin important when shopping for a diamond?
No where a diamond originates is not important in the value of the diamond. You should look out for conflict diamonds however. Conflict diamonds are diamonds that originate from areas controlled by forces opposed to legitimate governments. They are used to fund military action in opposition to those governments.
What advantages are there making diamonds in US?
Natural diamonds are a rare natural resource. Manufactured diamonds can be priced much lower than natural diamonds, and can be produced in a matter of days, not hundreds of thousands of years, which is required to form natural diamonds. The advantage may be to the consumer in being able to pay much less for a glorious diamond. (Be aware that manufactured diamonds are always detectable as manufactured, and should be accompanied by a certificate stating the origin of the stone.) In addition, any manufacturing adds jobs to any economy. You can read more about manufacturing gem diamonds, below.
What is the place of origin of a diamond?
Natural diamonds are formed far below the earth's surface in the earth's mantle. Then, they are erupted to the earth's surface through volcanic pipes. Man-made diamonds are grown in laboratories under high temperature and pressure.
What is the Difference between artificial diamonds and natural diamonds?
By artificial, one must assume that you mean not-natural diamonds, but diamonds formed in a laboratory. The difference is money. Natural diamonds are always more expensive than diamonds formed in a laboratory, given that all the elements about the stone are equal: cut, clarity, carat weight and colour. A certified gemologist will always be able to determine the origin of a diamond.
How a diamond reaches earth?
Diamonds are formed deep within the Earth's mantle under high temperature and pressure conditions. They are brought to the surface through volcanic eruptions, where they are found in volcanic pipes or kimberlite deposits. These diamond-bearing rocks are then mined and the diamonds are extracted for various uses.
