carbon
Well to be very upfront diamond is very heated and compressed carbon (coal graphite) while graphite is more "pure" carbon than diamonds
although they are formed from the same basic carbon, graphite's composition is only bonded on one plane so it makes it slippery. diamonds compositions is chemically bonded on 3 planes so it's much stronger, thus making it harder.

Diamonds are a crystallized form of carbon. While its atoms are no harder than any other carbon atoms, the arrangement of those atoms makes diamonds the hardest natural substance known to mankind.
There is only ONE element that makes diamonds. It is Carbon. Carbon has THREE(3) allotropes viz., Diamond, Graphite, and Buckminster Fullerene. An ALLOTROPE is were an element exhibits different physical characteristics.
Diamond and graphite are both pure carbon but graphite's atoms attach to three other carbon atoms and are connected in plates that are parallel to eachother. Diamond's atoms attach to four other carbon atoms in a crystal form, and graphite is a lot softer than diamond.
A diamond is more valuable than graphite because of its rarity, hardness, and brilliance. Diamonds are formed deep within the Earth's mantle under extreme pressure and temperature, making them relatively scarce. Additionally, their exceptional durability and unique optical properties make them highly prized in the jewelry industry.
unfortunately the only real chemical name for a diamond is Carbon .. makes this tough to send by mail with £2k insurance!
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.
Mother earth makes black diamonds.
Graphite does not react with oxygen at room temperature because graphite has a stable structure of carbon atoms bonded to each other in layers, which makes it highly resistant to chemical reactions. The strong carbon-carbon bonds in graphite make it difficult for oxygen to break into the structure and react with the carbon atoms.
Graphite is a form of carbon that makes a good lubricant due to its layered structure, which allows for easy sliding between layers. When used as a lubricant, graphite reduces friction between moving parts and provides long-lasting and effective lubrication.
