Olivine is mined in various countries around the world, including the United States, Norway, Finland, and India. Some of the major olivine mining locations include Hawaii (forsterite-rich olivine), Norway (fayalite-rich olivine), and Finland. These regions have significant deposits of olivine due to their geological history and processes.

A diamond will cut glass -- an emerald will not.

A diamond that is gray is filled with carbon, and irregularly shaped molecules, removing it from the gem-quality status only afforded about 20% of all diamonds mined.

If the stone is faceted, it may have been 'teaching' example for an apprentice stone cutter.

Because diamonds surface through eruptions of volcanic pipes from deep within the earth's mantle, the mined area around the pipe begins as a circle around the pipe and expands exponentially as the mine grows downward.

Diamonds are mined with heavy equipment that digs up shovel-fulls of earth and deposits them in large truck beds, which are then driven to sorting areas where the diamonds are separated from the earth that contains them.

The Hope Diamond is a blue diamond that contains trace amounts of boron, which gives it its distinctive blue color. It also contains nitrogen defects within the crystal structure, which can cause a red phosphorescence when exposed to ultraviolet light.

The clarity of an estuary can vary depending on factors such as sedimentation, nutrient levels, and tidal movements. Generally, estuaries are known for having lower clarity compared to open ocean environments due to the mix of freshwater and saltwater, as well as the presence of particles and organic matter from the surrounding land and water sources.

From Wikipedia:

"Moissanite /ˈmɔɪsənaɪt/ originally referred to a rare mineral discovered by Henri Moissan having a chemical formula SiC and various crystalline polymorphs."

Diamonds are formed from carbon.

Some gem-stone producers sell cut and polished moissanite as diamond replicas: moissanite is not diamond, but enjoys its own separate gem status.

Diamond is a form of carbon, an allotrope, which has the chemical symbol C and doesn't have a formula per se.

That's it. Just "C". It is pure carbon.

Diamonds are valued based on their colour, their cut, their clarity and their carat weight.

There are very few diamonds that exceed one pound in weight. Notably, the largest diamond found weighed just over 3,000 carats, which equals just over 600 grams, or about 21 ounces. Once cut and polished, its largest component weighed just over 106 grams, or 3.7 ounces.

A 4.36 round diamond J color and VS2 clarity with a very good cut is worth about $54,138. For details on this and other information, get in touch with us via www.dubaiwholesalediamonds.com/enquiry.

Diamonds are the hardest natural material and can only be easily scratched or broken by another diamond. However, extreme force or impact from a hard blow, such as a hammer, could potentially shatter a diamond.

Diamonds are not soluble in any liquid or substance due to their strong covalent bonds. The carbon-carbon bonds in diamonds are extremely stable, making them resistant to dissolution in most solvents.

A black light cannot test if a diamond is real or fake. Instead, professionals use instruments like a loupe, microscope, or thermal conductivity testers to assess a diamond's authenticity. The black light test is typically used for detecting fluorescence in some gemstones but does not accurately determine the authenticity of a diamond.

With the application of sufficient force, yes, a diamond can break. Diamond cutters do it all the time. They actually use a hardened steel chisel and a hammer to cleave diamond. Certainly a diamond can be broken using a hammer and an anvil, but that is a poor use of the tools and a waste of a diamond.

The Amazon rainforest in Brazil and other tropical rainforests are known to produce a significant amount of oxygen. Additionally, countries with large areas of forested land, such as Russia, Canada, and the United States, also contribute significantly to oxygen production. Ultimately, the total amount of oxygen production is a result of global forest cover and plant life.

Diamonds do not melt, but they can burn. Diamonds are formed at extremely high pressure and temperatures, but will burn in the presence of oxygen, like an oxygen torch at 1472 degrees Fahrenheit.

Diamonds have a density of about 3.5 grams per cubic centimeter, making them one of the densest naturally occurring materials. This high density is a result of the tightly packed carbon atoms in the diamond's crystal structure.

Simple answer: it is a pure substance

Non-Simple answer: Diamonds contain impurities in their lattice structure that are other elements, so technically it is slightly a mixture, but only if you get really picky about it.

The term citrine may be used here to describe a yellow diamond.

From Wikipedia:

"Citrine the most common reference for which is certain coloured varieties of quartz which are a medium deep shade of golden yellow. Citrine has been summarized at various times as yellow, greenish-yellow, brownish yellow or orange."

Diamond is usually a good insulator, and as it also has the highest thermal conductivity, these properties are used as a substrate under semiconductor chips for extracting the heat.

But some blue diamonds are a semiconductor, due to boron trace contamination, and these are used as a semiconductor material.

They are so different because of the way the carbon atoms bond to each other. Graphite has layers of very strong bonds, but the layers are very weakly bonded to each other. Diamonds are so strong because all of its carbon atoms are uniformly bonded to one another.

Very variable - some just look like lumps of dirty stone, while others have a visible octahedral shape and plenty of sparkle. Some look like little sugar cubes. The reference below has some photos of specimen examples. The largest diamond ever found (The Cullinan or Premier Diamond) appeared pretty unspectacular as it had no crystal faces and an eroded surface - see the second reference for a picture.
