Diamonds

Not necessarily. The speed of the diamond tester's beeping indicates the thermal conductivity of the stone, not its quality. A higher quality diamond may or may not beep faster, as factors like size and shape can also affect the speed of the beep.

No, magnetite is not harder than a diamond. Diamond is the hardest naturally occurring material known, ranking at the top of the Mohs scale of mineral hardness, while magnetite is relatively softer, ranking at around 5.5-6 on the same scale.

Yes you could if you had the materials, the extreme high temperature and pressure, and it would take a very long time to process. Your home is probably not the appropriate venue for the lab materials and equipment required to produce synthetic diamonds.

You can read more, below, about how the General Electric company attempted this task in the 1950s and see photos of their lab equipment.

Diamonds are typically clear or colorless with a brilliant shine. They are known for their hardness and durability, making them highly desirable for use in jewelry. Diamonds can also come in various colors such as yellow, blue, pink, and black, depending on the presence of trace elements during their formation.

Diamonds are not manufactured; they are mined from the earth's mantle through volcanic activity. However, lab-grown diamonds are artificially created using high pressure and high temperature or chemical vapor deposition techniques to simulate the conditions under which natural diamonds are formed. These lab-grown diamonds have the same physical, chemical, and optical properties as natural diamonds.

Diamond dust forms when very cold air comes into contact with water vapor in the air. The water vapor quickly transitions from a gas to a solid state without passing through the liquid state, forming tiny ice crystals that give the appearance of diamonds floating in the air.

Yes, diamonds are considered submetallic because they exhibit a high luster similar to that of metals, but they do not have the properties of a true metal. Diamonds are made of carbon and are the hardest known natural substance.

If you purchased a single gemstone of this weight -- translated into five carats of gemstone weight -- you can expect to pay between US$40,388 and US$443,987, depending on the cut, colour and clarity that you want. This is according to Blue Nile today (without endorsement).

If you want to purchase several gemstones totaling this weight, your cost would be different, again depending on the four Cs of the diamonds you choose.

If you purchase industrial diamonds, which one buys by the pound, your cost for one gram would be insignificant.

No, diamonds are harder than coal. Diamonds are one of the hardest natural materials on Earth, while coal is relatively soft and brittle.

yes and no

Not easily, it requires a great deal of force applied to a flaw in the diamond. Sometimes, however, if the diamond is flawed and it's hit 'just right', yes, the diamond can chip and become more than a single piece.

Yes, diamonds can scratch other diamonds. Diamonds are the hardest known natural substance, scoring a 10 on the Mohs scale of mineral hardness. Therefore, a diamond can easily scratch another diamond if sufficient force is applied.

Diamonds are extracted from diamond ore through a process called mining. This involves digging the ore-containing rock from the earth, crushing it to release the diamonds, and then separating the diamonds from the rest of the material using various techniques such as sorting by size or using density-based methods like dense media separation.

Depending on the context -- the sentence or phrase where NR is used -- it may mean 'natural round'.

Diamond waste refers to leftover materials generated during the process of cutting or shaping diamonds, such as dust or particles that are produced. This waste can also include used or damaged diamond tools that are no longer suitable for cutting or polishing diamonds. Recycling or properly disposing of diamond waste is important to minimize environmental impact.

Every diamond is worth what someone will pay you for it. Before you sell any diamond, regardless of its colour, pay for a certificate from a certified gemologist who will rate the diamond, according to its cut, colour, carat weight and clarity. Those details will help you establish a 'fair market value' for your diamond(s).

People who study diamonds are called gemologists. They specialize in identifying, grading, and evaluating gemstones, including diamonds, based on their quality and characteristics.

Diamonds exhibit a range of colors due to impurities, structural defects, and changes in their crystal lattice during formation. These variations can affect how light is absorbed and reflected, resulting in the different hues, including pink, yellow, blue, and green. Natural fancy colored diamonds are rarer than colorless diamonds, making them highly prized in the jewelry market.

The jeweler will test the jewel with a probe: the probe indicates whether or not and how electricity reacts with the jewel, to determine whether it is a diamond or (most) anything else.

A jeweler will use a probe to verify that a diamond is a diamond and not cut glass.

No, carbon cannot be removed from a diamond as it is a pure form of carbon. The structure of a diamond is a tightly bonded network of carbon atoms, and it is not possible to chemically or physically remove the carbon without altering the structure of the diamond.

No, diamonds are not biodegradable because they are very resistant to chemical reactions and natural decomposition processes. They are made of carbon atoms arranged in a crystal lattice structure that makes them extremely durable and non-biodegradable.

Green diamonds are referred to as "green diamonds". They get their color from natural radiation exposure that causes defects in the diamond's crystal lattice, resulting in the green hue. They are one of the rarest colored diamonds in the world.

A diamond will scratch anything and everything, including another diamond.

According to Wikipedia's definition of mineral, no.

"A mineral is a naturally occurring solid chemical substance formed through biogeochemical processes, having characteristic chemical composition, highly ordered atomic structure, and specific physical properties."

Black diamonds are tested using the same methods as other diamonds, such as measuring hardness using the Mohs scale, conducting a visual inspection for inclusions, and using tools like a loupe or jeweler's microscope to examine the stone's characteristics. Additionally, gemologists may use advanced instruments like a spectroscope or diamond tester to confirm a black diamond's authenticity and quality.
