Diamonds

According to Wikipedia, a craton is an "...old and stable part of the continental lithosphere" -- the earth's outermost rocky shell.

Kimberlite pipes, where diamonds are commonly found, are sometimes rooted in cratons.

Diamonds are found in various countries around the world, with major producers including Russia, Botswana, Canada, Australia, and South Africa. They are typically mined from kimberlite pipes or alluvial deposits. Industrial diamonds are also produced synthetically for various applications.

Carat weight is a measurement of a diamond or gemstone's weight, not its physical dimensions like length or width. Therefore, the carat weight of an 8mm cushion cut stone cannot be determined without knowing the specific density of the material.

Obsidian and diamond are formed under different conditions and from different materials, so obsidian cannot naturally turn into diamond. Obsidian is a volcanic glass formed from rapidly cooled lava, while diamonds are formed deep within the Earth's mantle under high pressure and temperature.

The first records we have of people deliberately looking for diamonds indicate that this happened in India. Diamond mining as an industry started there more than 2, 500 years ago.

Diamonds were prized from the very beginning. In fact, before the fifteenth century, diamonds were still so rare that only royal people owned them. It was not until 1430 that the custom of wearing a diamond as a personal ornament was introduced.

The cost of a natural diamond can vary greatly depending on its size, cut, clarity, and color. Generally, prices can range from a few hundred dollars to several thousand or even millions of dollars for rare and high-quality diamonds. It's best to consult a jeweler or diamond expert for specific pricing.

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.

You can find diamonds on every continent on earth except Europe and Antarctica.

If you simply want to try your chances of picking up a diamond, you can visit the Crater of Diamonds state park in Arkansas, USA. There, you can dig for diamonds and keep any that you find.

The study of rocks often involves examining the composition and structure of the Earth's crust, which includes the formation of diamonds. Diamonds are formed under high pressure and temperature conditions in the Earth's mantle, and studying rocks can help geologists understand the processes that lead to diamond formation. Additionally, diamonds are often found within host rocks, so studying these rocks can provide clues about the geological history of diamond deposits.

The rock that can be turned into a diamond is called carbon. Diamonds are formed from carbon molecules that have been subjected to high pressure and temperature deep within the Earth's mantle over millions of years.

Diamonds are considered nonrenewable resources because they are formed over millions of years deep within the Earth's mantle under extreme pressure and heat. Once they are mined and extracted, they cannot be replaced within a human timeframe.

Sure.

In the past people would not see diamonds set in silver or turquoise in gold. Now you see both, though not very common.

Turquoise has been found in silver in the South West, thus associated with silver.

Sterling Silver is a bit soft for setting diamonds, thus the setting either has to have some gold in it, or copper or be very heavy ( the prongs) of something to make up for the softness of the sterling. Thus the exact same style that you see done in gold could not be done in sterling . That does not exclude the combination though

Diamond blades are made by attaching small diamond particles to a metal core through a bonding process. The exposed diamond particles on the edge of the blade are what make it sharp and effective for cutting through hard materials like concrete and stone. Diamond blades are specifically designed to use the hardness and abrasiveness of diamonds to create a cutting edge.

Diamonds can change into graphite under extreme heat and pressure, as they are both forms of carbon. This transformation typically occurs deep within the Earth's mantle where such conditions are present.

Under extreme pressure, carbon atoms can form into different structures like diamond, where each carbon atom is bonded to four other carbon atoms in a strong tetrahedral network. This results in a very hard material with high thermal conductivity.

You buy one, or inherit one or trade someone for one.

They are both formed of the element carbon.

The streak of a diamond is transparent.
First of all, diamond is spelled 'diamond'. Next, diamond might seem like it has a streak when it scratches something but that is only a scratch. Diamonds do not have a streak.

Room temperature for a diamond typically refers to the ambient temperature of a room, which is around 20-25 degrees Celsius (68-77 degrees Fahrenheit). Diamonds do not have a specific temperature associated with them as they will adjust to the surrounding temperature.

Diamonds are mined, not quarried. Diamond mining involves extracting diamonds from the earth's crust, typically through open-pit or underground mining operations. Quarries, on the other hand, are used to extract building materials like stone, sand, and gravel.

Diamonds are mined in various countries around the world, with the top producers being Russia, Botswana, Canada, South Africa, and Australia. These countries have rich deposits of diamonds in their mines, which are extracted through open-pit or underground mining methods.

Diamonds are most commonly found in Africa, particularly in countries like Botswana, South Africa, and Angola. Other significant sources of diamonds include Australia, Russia, and Canada. These countries are known for their rich diamond deposits and large-scale mining operations.

An earthquake could affect geyser activity in Yellowstone by potentially altering the underground hydrothermal system that feeds the geysers. It could disrupt the flow of water and change the pressure within the system, impacting the timing and intensity of geyser eruptions. Additionally, an earthquake could trigger new geysers to form or cause existing ones to become dormant.
