i know carbon changes to diamond under heat and pressure over a really long time and carbon has its spot on the periodic table...but if diamond is from pure carbon, then why isnt diamond on the periodic table? are there things in a diamond besides carbon that enter into it when it changes?

Because a diamond is only a certain conformation of a group of carbon atoms. In a diamond, carbons align forming a superstructure of base 4 links that is extremely stable (that's why it is so hard to break].
Why it is not on the periodic table? Simple. It is a compound. Chemically, a diamond is C4, just like Ozone is O3, or Sulphuric Acid is H2SO4, and you don't see compounds in the table, just elements, even if compounds only contain one element.

Carbon is the element that is listed on the periodic table. Both diamond and graphite can be pure carbon, but their structures are different. If there are intrusions of other elements into diamond, it can be colored.

Yes it is pure carbon. You say it is not on the imperial table, - but it is! Under carbon. You see, 'diamond' is just our name for carbon crystalized under pressure over a long period of time. We could call it apple pie, but it is still wholly composed of only carbon, which is on the period table of elements.

Thats correct diamond is carbon heat and preasure but there is more Diamond is a crystal isometric cubic
It is the crystal structure of the diamond crystal that gives it the strength and hardness
This crystal structure is what makes it different from graphite
This link explains the crystal structure and how it makes diamond more than just carbon under heat and preasure

Diamond is considered the most expensive carbon..hehe
Yes it is Carbon, nothing else enters diamond except maybe air bubbles, which are usually termed as feathers.

a perfectly clear diamond is pure carbon. if it has any colour or flaws it is not pure. diamond is not on the periodic table because it is only one form of carbon.

Diamonds aren't one the periodic table because it's not an ATOM. It's composed of carbon atoms.

Yes. It is pure carbon. And so is graphite. They are allotropes of the same element. Since that element is carbon, then "carbon" is found in the Periodic Table.

Diamond refers to the crystalline arrangement of the carbon atoms. Silicon also bonds in the exact same manner (diamond structure). Carbon can also bond in hexagonal sheets called graphite, or in other forms like fullerenes and nanotubes. All of those things refer to the structure of multiple atoms, not of a single atom. The different forms of the same chemical substance are often called "allotropes."
All solids are either crystalline (ordered array), semi-crystalline (ordered over short distances), or amorphous (not ordered) in nature.

yes.
The reason it is a seperate name from Carbon is pure C mineral has two ploymorphs: diamond and graphite (pencil lead).
Diamod is bonded tightly between the C atoms in a cubic mannor. Graphite is sheet-like, with a weak zone that allows layers to come off (hense the ease in writing).
