Diamond has many unequaled qualities and is very unique among minerals. It is the hardest known substance, it is the greatest conductor of heat, it has the highest melting point of any substance (7362° F or 4090° C), and it has the highest refractive index of any natural mineral. Diamond is number 10 on the Mohs scale, and is approximately 4 …

What is Diamond? Diamond is a rare, naturally occurring mineral composed entirely of carbon.

2.3 Mineral Groups Most minerals are made up of a cation (a positively charged ion) or several cations, plus an anion (a negatively charged ion (e.g., S 2−)) or an anion complex (e.g., SO 4 2−). For example, in the mineral hematite (Fe 2 O 3), the cation is Fe 3+ (iron) and the anion is O 2− (oxygen). The two Fe 3+ ions have an overall charge of +6 and …

Graphite was named from the Greek "graphein" meaning 'to write' by German chemist and mineralogist A.G. Werner in 1789. It occurs most commonly in metamorphic rocks and is used as a lubricant, the manufacture of refractory crucibles and of course, pencils. It is easily distinguished by its greasy feel and the dark marks it leaves on hands.

Graphite. Pure graphite is a mineral form of the element carbon (element #6, symbol C). It forms as veins and disseminations in metamorphic rocks as the result of the metamorphism of organic material included in limestone deposits. It is an extremely soft mineral and it breaks into minute, flexible flakes that easily slide over one another.

The dark color, crystal form, hardness, and well-developed cleavage usually serve to distinguish these minerals from other common rock-forming minerals. The pyroxene group can appear in similar environments and has physical characteristics similar to the amphiboles: the two mineral groups can be distinguished based on the angles …

Feldspar is the name of a large organization of rock-forming silicate minerals that make up over 50% of Earth's crust. They are discovered in igneous, metamorphic, and sedimentary rocks in all components of the sector. Feldspar minerals have very comparable structures, chemical compositions, and bodily properties.

Graphite is most often found as flakes or crystalline layers in metamorphic rocks such as marble, schist's and gneisses. Graphite may also be found in organic-rich shale's and coal beds. In these cases, the graphite itself probably resulted from metamorphosis of dead plant and animal matter. Graphite is also found in veins and sometimes in ...
