Diamonds are formed as an allotrope of the element carbon, at depths greater than 90 miles. The pressure and heat at this depth is critical to the formation of the diamonds thâ¦at are mined at the surface today. At crustal pressures, the stable form of carbon is the allotrope graphite.
A diamond is not a compound; it is formed from carbon. Even though there are trace amounts of other minerals in diamonds -- such as nitrogen, which gives diamonds a yellow cas â¦ e -- diamond is not a compound, because the trace minerals cannot be separated out.he carbon atoms form  layers and the graphite is soft and slippery; which makes it a nice  dry lubricant that is sometimes used in lock cylinders. It's also  opaque; unlike diamond.     Diamond is an element, an allotrope of carbon.
