The mineral diamond can be found in various places. Diamonds are found on planets such as earth, uranus, neptune, saturn, and jupiter. The atmospheres of these planets have the perfect temperature and air pressure conditions to host the carbon in form for the diamond. Diamonds must be in an area with very high temperatures and high pressure for the diamond minerals to be able to form. They need the high temperatures to allow them to become stable ad have a good foundation. The identifying characteristics

which the three most well known are diamond, graphite, and graphene. Depending on the allotropic form, the physical properties of carbon vary, for example, the diamond is transparent and graphite is black and opaque. I also chose carbon because it has untapped potential to benefit our lives and its many uses continue to expand. The diamond is a carbon allotrope made up of carbons tetrahedrally bonded in a structure called a diamond lattice. The very rigid diamond lattice combined with strong covalent

may think diamond are just used for jewellery and fashion but what you may not know is they can be used to revolutionise our technology used in computers, mobile phones and even our everyday appliances!
