Yes diamond is a mineral
Yes, diamond is a mineral

It has been found in many different

parts of the earth as shown below


Many diamonds were found in the kimberlite pipe kimberley south africa
Many diamonds were found in the kimberlite pipe, Kimberley, South Africa


Diamond is crystalline with a fixed chemical composition carbon c
Diamond is crystalline with a fixed chemical composition -- carbon (C)

A single crystal with a

well-developed external form

The unit cell of diamond structure showing how carbon atoms inside are arranged.



  • minerals so far.

  • Only 200 of them are commonly

  • observed.

  • 20 of them are important rock-

  • forming minerals.


  • 7 amazing minerals
    7 Amazing Minerals carbon (C)


    1 diamond
    1. Diamond carbon (C)


    The hardest mineral on earth
    The hardest mineral on earth carbon (C)

    “Diamond is forever”


    2 quartz
    2. Quartz carbon (C)


    The most abundant mineral on the earth s surface quartz rock crystal sio 2
    The most abundant mineral on the earth’s surface -- carbon (C)quartz (rock crystal) SiO2


    The mineral we eat daily table salt nacl halite
    The mineral we eat daily –table salt carbon (C)NaCl (halite)

    Cl-1

    Na+1

    The mineral halite has a typical ionic bonding

    between Na+1 and Cl-1

    The unit cell is face-center cubic


    3 mica
    3. Mica carbon (C)


    The mineral that looks like a stack of papers
    The mineral that looks like a stack of papers carbon (C)

    mica – a sheet silicate


    4 magnetite
    4. Magnetite carbon (C)


    The mineral that attracts iron metals
    The mineral that attracts iron metals carbon (C)

    magnetite – an iron oxide (Fe3O4)


    5 pyrite
    5. Pyrite carbon (C)


    The yellow mineral that fools many people as gold
    The yellow mineral that fools many people as gold carbon (C)

    pyrite

    (FeS2 )

    The cubic crystal

    of pyrite

    Crystal structure –

    a face-center cubic


    Interesting features of pyrite fes 2
    Interesting features of pyrite, carbon (C)FeS2

    Clear striations on the surface

    The black color for

    pyrite powder

    The simplest way to produce powder from minerals is to scratch a sharp edge of a specimen against a rough & hard ceramic plate. You may try a pyrite specimen on the table to see if it is correct.


    6 ice
    6. Ice carbon (C)


    The mineral that floats on water
    The mineral that floats on water carbon (C)

    Ice – the solid form of water, H2O


    7 olivine
    7. Olivine carbon (C)


    A green mineral called hawaii diamond
    A green mineral called Hawaii diamond carbon (C)

    Olivine – a silicate, (Fe, Mg)2SiO4


    Interesting facts about the olivine mineral
    Interesting facts about the olivine mineral carbon (C)

    olivine crystals in the basalt

    It is the first mineral crystallized out from the molten magma.

    Puu Mahana, Green Sand Beach, Hawaii

    It is the major component for the green sand.


    The most abundant mineral in the earth s upper mantle below the crust and above 410 km depth
    The most abundant mineral in the earth’s upper mantle carbon (C) (below the crust and above 410 km depth)
