Diamonds

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.

It is, so diamond will become graphite over time. The structure of diamond hinders the necessary kinetics, so the process is very slow, unnoticeable most of the time.

It's because the standard enthalpy of formation of graphite is 0; but diamonds is not equal to 0.

According to Wikipedia:

" ...cushion antique brilliant [cut] with a faceted girdle and extra facets on the pavilion."

There are about 1.092 x 10^21 carbon atoms in 2 grams of 1 carat diamond. This is calculated based on the molar mass of carbon and Avogadro's number.

Yes, a laser cutter can cut diamond because diamond is a carbon-based material, and carbon can be vaporized by a high-powered laser. However, the process can be challenging due to diamond's exceptional hardness, which can damage the laser cutter's lenses and mirrors. Specialized techniques and equipment are required for cutting diamonds with a laser cutter.

Diamonds are measured in carats, which is a unit of weight equal to 200 milligrams. This weight measurement is used to determine the size and value of a diamond.

Diamond is a form of the element carbon that forms a covalent network structure, where each carbon atom is bonded to four other carbon atoms in a tetrahedral arrangement. This results in a very hard and rigid structure, making diamond the hardest known natural material.

No, diamonds are not found on Venus as it is primarily composed of rock and metal. The harsh conditions on Venus, including extreme heat and high pressure, would not be conducive for diamond formation.

A collection of diamonds is typically referred to as a "parcel" or a "lot."

100 percent natural diamonds are diamonds that are formed in the earth's mantle over millions of years through natural processes without any human intervention or enhancement. They are not synthetic or lab-grown diamonds.

Yes, carbon can crystallize under extreme heat and pressure to form diamonds. Diamonds are pure carbon crystals that have a tightly packed and highly organized structure, making them one of the hardest natural materials on Earth.

the diamond has no streak because it is the hardest mineral

No, diamond is a nonpolar molecule because it consists of carbon atoms arranged in a symmetrical tetrahedral structure, which results in an overall neutral distribution of charge. This means that diamond does not have a net dipole moment.

Any raw diamond must be seen to be evaluated for its value, because so much will be lost when the stone is cut and faceted.

You have the total carat weight of the uncut stone, and you've indicated that the diamond is 'white', but the clarity and the grade of white will determine ultimately how high the final owner can price the cut stone.

Find a certified gemologist who will help you evaluate a raw diamond, and potentially, who can direct you to a reputable diamond cutter.

For diamonds, carat is the weight. I suspect that your 1.0 stone is a 1 carat stone.

Milliliters (ml) is a measure of liquid volume, which doesn't apply to diamonds, since they are not liquid.

To determine the estimated value of an opal necklace and earrings surrounded by small diamonds, you can take them to a trusted jeweler for appraisal. They will assess the quality and characteristics of the opals, diamonds, and settings to provide an estimated value based on current market trends. Make sure to get a written appraisal for insurance purposes.

One way to differentiate between a diamond and glass is through their hardness level. Diamonds are one of the hardest natural substances, so they can scratch glass, while glass cannot scratch a diamond. Another method is through their refractive index; diamonds have a higher refractive index than glass, leading to more sparkle and brilliance in a diamond compared to glass. Consulting a professional jeweler or gemologist is the most accurate way to determine if a stone is a diamond or glass.

Diamonds come out of the ground looking like rough, unpolished crystals. They may appear cloudy, dull, and in various shapes such as octahedral or cubic. The raw diamonds have a rough texture and must be cut and polished to reveal their natural sparkle and beauty.

No, diamonds are not considered a renewable resource. They are formed deep within the Earth's mantle over millions of years through intense heat and pressure. Once a diamond is mined and used, it cannot be replenished within a short time frame.

Diamonds are mined all over the world, including Canada, the USA, Russia, Australia, Germany, Brazil, South Africa, even Sweden.

Note, however, that there are no diamonds mined in Europe or Antarctica.

An authentication process for a diamond is usually formalized on paper. You can find an example, below.

Any mark stamped into the jewelry metal cannot authentically reflect the stones set into the metal, since the metal and the stones can easily become separated.

Any laser mark on a diamond will be an identification mark for the stone. The stone's authenticity, then, must be pursued through the holder of the mark and paper authentication obtained through them.
