Diamonds

No, diamonds cannot be made directly from human ashes. While it is possible to create memorial diamonds using carbon extracted from cremated remains, the process involves high pressure and high temperature treatments in a lab setting, rather than simply transforming ashes into diamonds.

Diamonds are formed deep within the Earth's mantle layer, around 150 to 200 kilometers below the surface. They are brought closer to the surface through volcanic activity and then mined for various industrial and jewelry purposes.

It is not typically possible to find diamonds in a coal mine. Diamonds are typically formed in the Earth's mantle, while coal is formed from plant material that has been subjected to high pressure and heat over time. The two processes occur in different geological settings.

Yes, diamonds are the hardest known natural material on Earth with a Mohs hardness scale of 10. However, it is important to note that hardness and toughness are two different properties. Toughness refers to a material's ability to resist breaking or shattering under force, and in this regard, some materials like metals may exhibit better toughness than diamonds.

When a diamond is cut or set, it is possible to do so with its flaws presented in a way that makes the diamond vulnerable to chipping. Either of these situations is rare if the diamond is cut or set by knowledgeable workers.

A less flawed diamond is less susceptible to chipping.

No, crushed calcite is not hard enough to grind or form facets on a diamond. Diamonds are the hardest natural material on the Mohs scale, while calcite has a much lower hardness rating. Specialized tools with materials of equal or greater hardness, such as diamond powder or industrial diamond grit, are typically used to cut and shape diamonds.

Yes. While diamonds are high-priced commodities, and usually have gold, silver or platinum bands, the actual ring could be made of any suitably hard and durable material. Early jewelry was made from copper and bronze, and rings of stainless steel, nickel, or titanium alloys would function just as well.

Up to one hundred percent of every diamond is carbon, with trace amounts of other minerals that may give the diamond a colour.

In the strictest definition, chemically, diamonds do not effervesce -- give off gas. However, visually, one could describe a diamond as vivacious, which is another definition of the word you wrote.

The clarity of a chromatogram can be improved by optimizing the chromatographic conditions, such as adjusting the mobile phase composition or flow rate, using a column with better resolution, and ensuring proper sample preparation techniques. Additionally, improving the detector sensitivity and reducing background noise can also enhance the clarity of the chromatogram.

Diamond accents generally refer to small diamonds that are used to enhance the beauty of a piece of jewelry, but they are not the main focus. They are usually smaller in size and lower in quality compared to the main center diamond. It's essential to check the description and specifications of the piece to determine if the diamonds are genuine or simulated.

People use the glass test to check if a diamond is real because diamonds are harder than glass. If a diamond is real, it will scratch the glass, whereas a fake diamond will not leave a mark. This method is not foolproof and other tests are recommended for a more accurate assessment of a diamond's authenticity.

Boiling a diamond in grease will not harm the diamond itself, as diamonds are one of the hardest natural substances. However, the grease may become heated and bubble over, potentially causing a mess or fire hazard. It is not recommended to boil a diamond in grease.

You can melt a diamond, because anything can melt given enough heat. Diamond, however, has the highest melting point of any known mineral: 3820 degrees Kelvin, 6416.33 degrees Fahrenheit, or 3546.85 degrees Celsius.

To determine if your chocolate diamond is real, you can have it professionally appraised by a gemologist. They will be able to authenticate the diamond based on its unique characteristics such as color, clarity, and certification. Additionally, you can look for reputable sources that provide certificates of authenticity for chocolate diamonds.

Yes. You can either buy a diamond chip already mounted in a piece of jewelery, or you can chip your diamond if it is exposed by improper setting in such a way that a blow can chip the stone at a weak spot in its lattice.

Every diamond is rated by its colour and clarity differently, along grades for each measurement.

Tiffany and Company will gladly provide you with certificates that detail the colour and clarity -- and carat weight and cut -- of any diamond you purchase from them.

Generally, a smelting operation to recover gold, would remove the gems before depositing the gold material into the furnace.

The disposition of the gems is determined by whomever owns them after they are removed from their settings.

The color scale for white diamonds runs from D to Z. On one end of the spectrum you have completely white without any traces of yellow and on the other end, a diamond fully saturated with yellow and no traces of whiteness. Due to the fact that they are quite common, they are actually quite affordable.

One of the easiest ways to tell if a diamond is fake is by conducting a fog test. Simply breathe on the diamond and observe how quickly it clears. A real diamond will disperse the fog quickly, while a fake diamond will hold the fog for a few seconds.

Yes. Diamond cuts through everything. In fact, diamond is the hardest natural material on Earth. (Diamond or laser can cut diamond.)

The question was 'why'... the answer is because it is the most compressed carbon based material.

If you suspect that the testing instrument is malfunctioning, contact the manufacturer to confirm the malfunction and follow their instructions to bring the instrument back to its intended veracity.

If the instrument that you're using to test a diamond doesn't give you the result you want, you can use another instrument to test the diamond.

You can also take the 'two out of three' approach, and use three different testers to confirm the substance being tested.

Nothing. Only other diamonds can cut diamonds.

Diamonds are one of the hardest naturally occurring materials, so they can only be scratched or cut by another diamond. However, because of their structure, diamonds can still be shattered or damaged by a hard blow, so it is important to handle them with care.
