Natural diamond is a mineral composed of a single element–carbon (C). It has a cubic crystalline structure. It generally occurs in the form of octahedral crystals with curved faces, with cubic crystals being rarer. Diamonds are usually colorless.
What mineral group is the diamond?

What is an example of mineral with diamond?
Also found with diamonds are olivine, serpentine, carbonates, pyroxenes, pyrope garnet, magnetite, hematite, graphite and ilmenite. Near the surface, kimberlite weathers, producing yellow loose mass called yellow ground, while deeper in Earth, it changes to more dense blue ground.
Are diamonds classified as minerals?
diamond, a mineral composed of pure carbon. It is the hardest naturally occurring substance known; it is also the most popular gemstone. Because of their extreme hardness, diamonds have a number of important industrial applications.
Is diamond A metallic mineral?
Diamonds are composed of pure carbon. Carbon is definitely a non-metallic element. so diamond is a non-metallic mineral.
What type of rock is diamond?
Background. The diamond is the hardest natural substance known. It is found in a type of igneous rock known as kimberlite. The diamond itself is essentially a chain of carbon atoms that have crystallized.
Are diamonds a compound?
The quick answer is: Diamond is a pure element, carbon; gold is a pure element, gold; and rust is a compound, Iron Oxide, of iron and Oxygen. Diamond is pure elemental carbon, compressed to its crystal form, under extreme heat and pressure deep within the Earth.
Is diamond an element compound or mixture?
It’s a heterogeneous mixture. Diamond is made of just one element: carbon. Each carbon atom in diamond is connected to four other carbon atoms, in a crystal that extends on and on. There are other forms of pure carbon where the atoms are bonded differently, notably charcoal and graphite.
Are diamonds made from coal?
Over the years it has been said that diamonds formed from the metamorphism of coal. According to Geology.com, we now know this is untrue. “Coal has rarely played a role in the formation of diamonds. … The diamonds form from pure carbon in the mantle under extreme heat and pressure.
How do you tell if a mineral is a diamond?
The only hardness test that will identify a diamond is scratching corundum. Corundum, which includes all rubys and sapphires, is 9 on the hardiness scale. If your suspected diamond crystal can scratch corundum, then there is a good chance that you found a diamond. But NO OTHER HARDNESS TEST will identify a diamond.
Is a diamond considered a rock?
A rock is made from two or more minerals. A mineral might contain just one chemical element or more than one element. … The diamond is the Earth’s hardest mineral. A diamond is so hard that it’s possible to cut a diamond with another diamond.
What are the minerals?
A mineral is a naturally occurring inorganic element or compound having an orderly internal structure and characteristic chemical composition, crystal form, and physical properties. Common minerals include quartz, feldspar, mica, amphibole, olivine, and calcite.
Is diamond a non metallic minerals?
Non-Metallic Minerals – Those minerals which do not contain metals are called non-metallic minerals. Examples of non-metallic minerals – diamond, mica, salt, potash etc. The Kohinoor diamond placed on the crown of England’s queen is an example of non-metallic mineral.
What are diamonds made from?
Diamonds are made of carbon so they form as carbon atoms under a high temperature and pressure; they bond together to start growing crystals.
Is diamond the hardest metal?
Diamond is the hardest known material to date, with a Vickers hardness in the range of 70–150 GPa. … In this way, metals with high bulk moduli but low hardness are coordinated with small covalent-forming atoms to produce superhard materials.
