DeBeers artificially keeps the price of gemstone quality diamond high by restricting the ammount of diamonds that are on the market. Although top quality diamonds can be grown in the lab for about 200$ per carrot, there are few companies that have the ability to take on the larger gem mining companies. In addition people seem to think that a lab grown gem is somehow worth less than its mined partner, but that's only because diamonds are overpriced in the first place and most people know nothing about chemistry.
Because diamond is charcoal that has been under extreme pressure and very high heat for thousands if not millions of years and are therefore very rare.
yes charcoal is simply carbon. Though other impurities may be present.
Graphite is less dense than diamond, due to the differences in crystal structure.
Not necessarily. An element is a pure substance. You may find a pure element in a molecular form, such as Cl2 gas. A diamond could be considered to be a very large, single "molecule" of carbon. The technical answer to your question is 'no', though you may say yes if you are loose with definition. I suspect the answer you want is 'no'.
Sp is not a symbol for a chemical element.
No, starch is not in the periodic table because starch is not a element.
No, charcoal is considered a mixture with different substances in it, but if you have pure graphite, it is considered an allotrope of carbon (like diamond).
Diamonds are pure carbon, a useful form of clean burning fuel. In an 800 degree oven, and an oxygen atmosphere, the diamond burns cleanly and turns into Carbon Dioxide gas. Its an expensive way to heat your house. +++ LOL! Carbon is certainly a very useful fuel in its more common though artificially-modified versions (coke and charcoal), but certainly not in its diamond form!
Yes--charcoal is partially-burned wood. Charcoal briquets, though, are a different thing--charcoal plus binders plus petroleum derivatives...
Diamond !... DIamond is the hardest (known) natural element on the planet. Small pieces of diamond help the drill bit cut though tough obstacles such as rock.
Chocolate diamond rings are slightly less expensive that normal diamond rings so are a good option if you are looking to propose on a budget. The cheapest available are å£55 though you can pay in excess of å£7000 for a large stone with an expensive cut.

You don't "find" charcoal. You obtain charcoal by creating it with a wood log. Don't smelt Wooden planks, though you may use it as fuel.
Carbon is the element from which Diamond is formed. Just pure carbon. Made deep in the Earth. The hardest substance known (though all diamonds are not equally hard) and rates 10 on the Mohs hardness scale. This is an arbitrary scale. The hardest diamonds come from the NSW fields of Australia, and are in demand as polishing material. Diamonds also have the highest 'melting point' of the elements - around 3820oK. They have the highest thermal conductivity -- about 400 times that of copper. Other allotropes of carbon are charcoal, graphite, and perhaps graphene.
Graphite is less dense than diamond, due to the differences in crystal structure.
Parents should not mix charcoal with chocolate syrup, sherbet, or ice cream, even though it may make charcoal taste better. These foods may prevent charcoal from working properly.
You can find a good selection of charcoal grills at places such as osh and amazon. They have a better selection at amazon, so you check there instead though.
