composition
Both diamonds and graphite are allotropes of carbon.
NO!!! However, as an allotrope of carbon , they will change to graphite (another allotrope of carbon) on heating.
Black diamonds, also known as carbonados, are composed of carbon atoms, just like traditional diamonds. However, black diamonds contain abundant inclusions and graphite, which give them their distinctive dark color. They are more porous and polycrystalline in structure compared to regular diamonds.
It depends on what form its in. Most forms of carbon are opaque. Diamond, however, is transparent.

they don't conduct electricity: they have no free electrons. graphite, however, made of the same stuff as diamond (carbon) has a different structure, which means that it does have free electrons, and a lot of them. Therefore graphite is a good conductor of electricity.
Some minerals contain carbon, such as graphite and diamonds, however while they both contain carbon, the diamonds density is far greater.
Both diamonds and graphite are allotropes of carbon.
Diamond (and also graphite) is pure carbon, without iron. Heating graphite and subjecting it to intense pressure can make small industrial diamonds.
NO!!! However, as an allotrope of carbon , they will change to graphite (another allotrope of carbon) on heating.
If you are referrring to lead as the thing that is found in pencils, then the lead is actually graphite, and graphite and Diamond are both pure carbon, just arranged differently chemical composition.
Yes, diamond and graphite are isotopes of carbon as they are both entirely made of carbon. However they have very different structures resulting in their different properties.
By definition, a mineral must form by natural processes. So anything man-made, even if it is chemically an structurally identical to a mineral, is not a mineral. However, natural diamond is formed from graphite as well.
They are not made the same- but they come from the same element- carbon. However, carbon can take different crystal shapes. One of those is graphite, a very different one is diamond.
Natural black diamonds are rare. They are due to dark graphite inclusions. Their rarity makes them valuable. Most black diamonds are synthetic and made by heat treating low quality diamonds. The price of a synthetic black diamond is lower than that of white diamonds.
Blue diamonds do not conduct electricity. Diamonds do, however, conduct heat, in fact five times better than silver. Both diamonds and graphite are produced naturally from carbon. Diamond is an excellent electrical insulator, graphite is a good conductor of electricity.
