What temperature does diamond melt at?
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.
Is a diamond a pure substance or a mixture?
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.
How can diamond and graphite be made out of same substance and be so different?
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.
What does the raw form of diamond look like?
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.
How do you know if a diamond is real?
I've been told true diamonds will cut glass & if you have it examined by a Jeweler DO NOT leave it overnight as you may receive a fake back. GOOD LUCK. Heavy Liquid Method: Keeping the diamond in "clerici diluted solution" (poisonous) of S.G. 3.52 will suspend (neither floats nor sinks) whereas other stones will either float or sink. The actual cleric solution has S.G. of 4.00 but with added "methylene iodide" and with help of indicator stone (diamond) will make the solution of similar S.G. that of a diamond i.e. 3.52. This "clerici diluted solution" is one heck a solution to identify diamond from rest of the gemstone world.
What is the process of creating diamonds called?
A diamond is created when soot or coal is subjected to intense heat and pressure for a long period of time. What this does is rearrange the molecular structure of the coal, creating a new one which is what we call diamond. This different structure is also called an allotrope of coal in case you were wondering. Now the process of of heat and pressure is the same that changes metamorphic rocks, so in a very base (and probably wrong) sense I would called the changing process metamorphsis.
Beauty comes from inside. Beauty is not on the outside! It isn't how pretty a girl/boy is. Beauty is passion, and being kind inside. People can be beautiful on the outside, but that isn't beauty, because they can also be harsh, and shallow. Ugly, nice people are beautiful. They are kind, and that's what really counts!

What is the real name of a plant called diamond dust?
There is a bird's nest type of Anthurium that is called 'Diamond Dust'.
How do you know if your diamond is real?
In the old days, just scratch a piece of glass. If the glass scratches and the diamond is fine, then you have a real diamond.
However, today, with manufactured diamonds, it's not so easy.
For clarity, the best solution is to take it to a jeweler and get it tested, and valued at the same time, as you will need this to insure it - as it will be a real diamond, you will want to insure it.
Another Answer
Any diamond is a real diamond, regardless of whether Mother Nature 'manufactured' it, or it is the product of a human manufacturing process.
A human-process diamond is worth less than a natural diamond, but a diamond, nonetheless.
A certified gemologist can verify the origin of your diamond -- a jeweler may not have the skills or experience to identify a stone's source. You pay for a gemologist's report, which you'll also need, should you require claim reimbursement under your insurance policy.
What does the stone tablet in diamond do?
The stone tablet in Pokémon Diamond allows you to access the Mystery Gift feature. This feature lets you receive special event Pokemon, items, or unlocks in the game. You can connect with other players to receive gifts or attend official events to obtain exclusive items or Pokemon.
Which African country produces the most coal?
South Africa is the largest producer of coal in Africa. The country's coal industry has played a significant role in its economy and energy production.
Should you boil diamonds and gold?
If you're attempting to clean this metal and these gemstones, bursts of high-pressure steam will clean them better than boiling them. Boiling them may loosen dirt and debris collected over time, but it will not 'clean dirt out' of the setting, which is what you want.
Neither process will remove tarnish from gold: a jeweler can polish your gold if the tarnish offends you.
You can test a diamond by checking for its clarity, color, cut quality, and carat weight. Other methods include examining it under a loupe for any inclusions or imperfections and using a diamond tester to confirm its authenticity. Consulting with a certified gemologist or jeweler is also recommended for a professional assessment.
Diamonds shine due to their high refractive index, which causes light to bend and reflect within the stone, creating a dazzling sparkle. The facets on a diamond's surface also help to reflect and scatter light, enhancing its brilliance.
the diamond is very hard because it has crystallized at depth of 140-150 km( sometime it has crystallized at 300-400 km) into the earth to high pressure ranging approcimately betwen 45-60 kilobars and low temperature ranging approximately betwen 1652-2372 F(900-1300 C).
AnswerIts hard because it consists of very small atoms (carbon) that are then tightly packed together and linked via covalent bonds (bonds where two atoms share an electron). It is the combination of very tight packing and very tight linking that results in diamond being so hard.Why has diamond have high melting point?
Diamond has a high melting point because of its strong covalent bonds between carbon atoms, which require a significant amount of energy to break. These bonds are arranged in a rigid lattice structure that makes it difficult for the atoms to move freely, resulting in a high melting point for diamond.
A diamond is a crystalline form of the element carbon. Because of its structure, it is considered the hardest naturally-occurring substance. It is transparent, but so dense that light passing through a diamond is slowed by nearly 50% of its speed.
Diamonds can be 'cut" by other diamonds, or split along its crystal lines to produce shimmering jewels that last practically forever.
Diamonds are formed when carbon is placed under many tons of pressure and extreme heat for a million years or longer, causing the carbon atoms to form a tight lattice. They can be produced artificially using special furnaces, as can other familiar gemstones such as rubies, emeralds, and sapphires.
The meaning of Diamonds in the Greek language is unbreakable. Due to the nature of the stone it is also believed that if this stones are used for the weddings, the bond between the couples will be everlasting like the nature of the stone. This is one of the most loved gemstone.
'Important' is a judgment-driven word, and when used with 'diamond', presents a question that can generate lots of opinions.
Per se, no, diamonds are not 'important', in the sense that they are not required for daily life.
However, because of their size and value, gen-quality diamonds can be important repositories of wealth for owners who can use them to barter or buy their way out of life-threatening situations.
Industrial diamonds are important, because diamond-tipped tools are required for fabrication tasks that involve harder raw materials.
What does the awakening stone do in diamond?
In Pokémon Diamond, the Awakening Stone is an item that boosts the power of Ghost-type moves used by Giratina while it is holding it in battle. When Giratina holds the Awakening Stone, its Ghost-type moves such as Shadow Ball and Shadow Claw will deal more damage.
Where To Get TM 25 Thunder On Diamond?
In the Department Store in Veilstone City. 3rd floor. Cost: 5500
Or, go to one of the three lakes and surf around the edges and you'll find a little area of land, run around there and you will find Blizzard at lake Acuity, Thunder at Lake Valor, and Fire Blast at lake Verity I think.
You have to have saved the Three Beings from Team Galactic first.
Ok what u need to do is save the threee beings of each lakes then u can go to each lake and search around the each of the edges at lake aquity u can find blizzard at lake valor u can find TM 25 thunder and at lake verity fire blast so yeah pretty cool and also u can find TM 25 thunder at the game corner in veilstone city
ur man diamond497 any Pokemon info come 2 me kk
Not Toxic, But Can Still Cause Harm to Bodies
No, diamonds are composed mostly of carbon which is not poisonous. They are indigestible so while not being toxic, they could potentially cause harm to your digestive system if you were to actually consume one. True, too, of an animal.
Diamond is insoluble in any solvent present on Earth. When consumed, the solid form only will pass through the system, without any change. Nothing will mix up in the body. But, it could choke or block a system because of its hard structure, depending on its size and the object in which it is mounted.
No diamond is fake; but there are fake diamonds.
Because natural diamonds are expensive and engaging to the human eye, many people want to own and wear diamonds, so a fake diamond can be substituted in the place of a real stone.
