Diamonds

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.

The Hope Diamond gets its blue color from trace amounts of boron in its crystal structure. This impurity absorbs certain wavelengths of light, giving the diamond its distinct blue hue.

Diamonds are the hardest natural substance, so crushing them requires a significant amount of force. One common method is to crush diamonds with a hydraulic press that exerts high pressure. Another method is to use diamond powder or grit in a hammering process to break down larger diamonds into smaller pieces.

Low quality diamonds are often called industrial diamonds. These diamonds are not suitable for use in jewelry due to their poor clarity and color, but they are valued for their hardness and used in various industrial applications such as cutting, drilling, and grinding.

The name of the substance in diamonds is carbon.

(When you indicate 'white' one must assume the D colour. There may be larger stones in the world, but this is the largest graded with a D colour.)

Apparently, it is the DeBeers Centenary Diamond, described as weighing in at 273.85 carats (54.77 g). It is a D colour stone, and is internally and externally flawless.

Some 'impurities' are known: nitrogen causes yellow, gold and green; boron causes blue, other diamond colours are not so obvious. For example, pink diamonds are probably caused by a distortion in the diamond's lattice formation: the cause remains somewhat of a mystery.

Diamond is the hardest natural mineral on earth. That this mineral has the highest melting point of any mineral -- 3820 degrees Kelvin -- is logical.

Diamonds are formed from carbon deep within the Earth's mantle under extremely high pressure and temperature conditions. Over millions of years, the carbon atoms undergo a process of crystallization, forming the strong, tightly packed structure characteristic of diamonds. Through volcanic eruptions or other geological processes, diamonds are brought closer to the Earth's surface, where they can be mined.

One carat of diamond weight equals 0.2 grams. One gram equals 1000 milligrams.

Can you do the math?

No, diamonds cannot be made out of soap. Diamonds are formed under high pressure and temperature deep within the Earth's crust, while soap is made from natural oils and fats.

If you are not a jeweler than the best way is to ask for gemological report at GIA, EGL, IGI. Which will confirm the origin of diamond and it's characteristics. For more information on synthetic diamond follow my link below.

Take the two and scratch them off of each other. Which ever is scratched is the crystal. Diamonds are always harder. You can also try to scratch it off of other things too, but the diamond will never scratch.

Diamond is the hardest material because of its unique crystal structure, with carbon atoms arranged in a strong, tightly bonded lattice. These strong covalent bonds prevent the atoms from easily separating, making diamond resistant to scratching and wear. It also has a high melting point, further contributing to its durability.

The unit of weight for diamonds equal to 2mg is called a "point." In the diamond industry, one point is equivalent to one one-hundredth of a carat. So, 50 points would be equal to 0.50 carats.

Moissanite presents an interesting alternative to diamonds, insofar as gem-quality 'bling' is concerned. Some describe it as a substantive alternative to diamond many times more valuable than other diamond alternatives.

Because of natural moissanite's innate physical and chemical properties, it is difficult for the untrained eye to identify as different from diamonds.

A certified gemologist will always be able to identify moissanite, because its base composition from silicon carbide is fundamentally different from a diamond's composition of carbon.
