What is Diamond Mineral?
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.
What type of rock is Diamond?
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. The stone’s unique hardness is a result of the densely concentrated nature of the carbon chains.
Is Diamond A mineral resources?
Diamond is an extremely stable form of carbon: It is a material with superior physical properties due to the very strong covalent bonding between the carbon atoms. … Diamond has the highest hardness and thermal conductivity of any known natural or synthesized material.
What minerals are found around diamonds?
It is formed deep in the mantle and is only brought to the surface via kimberlite pipes, lamprophyres, eclogites and other rocks that originate deep within the mantle. It is also found in alluvial deposits, along with quartz, corundum, zircon and other minerals, derived from such rocks, and in certain meteorites.
What is the rarest color of diamonds?
In diamonds, rarity equals value. With diamonds in the normal range, value is based on the absence of color, because colorless diamonds are the rarest. With fancy color diamonds—the ones outside the normal color range—the rarest and most valuable colors are saturated pinks, blues, and greens.
Where is Diamond used?
Diamonds are used for industrial purpose. Its property of hardness is useful to drill, grind or cut materials. Hence, some blades used for cutting and drills in the industry used diamonds. They are present on the edges and tips in small sizes.
How can you tell a raw diamond?
Put the diamond under the loupe or microscope and look for rounded edges that have tiny indented triangles. Cubic diamonds, on the other hand, will have parallelograms or rotated squares. A real raw diamond should also appear like it has a coat of vaseline over it. Cut diamonds will have sharp edges.
Are diamonds found in granite?
The diamond is the Earth’s hardest mineral. A diamond is so hard that it’s possible to cut a diamond with another diamond. Rocks divide into three different groups according to how they are formed. … Igneous rocks include basalt, granite, obsidian, and pumice.
Can you find diamonds in rivers?
Diamonds are found naturally in Kimberlite rocks or alluvial deposits. … These rocks are carried by rivers, streams and waterfalls and diamond crystals are deposited in the water hence the pacer or alluvial deposits.
Why is diamond so expensive?
A diamond is the hardest material on the earth and the most expensive gemstone as well. Diamonds are not rare but high-quality diamonds that can be used in the jewelry are rare. … In addition, the size and quality of the diamond also plays a major role on the price. These are the reasons why diamonds are so expensive.
What happens if you find diamonds on your property?
If you ever find a diamond ring, or any lost property, don’t assume that you can keep it. Always attempt to find the owner if possible, or turn the item in to the police. Most states will allow finders to keep the property if the owner does not show up to claim it after a certain time.
What is diamond mineral used for?
|Physical Properties of Diamond|

|Chemical Composition||C (elemental carbon)|
|Uses||Gemstones, industrial abrasives, diamond windows, speaker domes, heat sinks, low-friction microbearings, wear-resistant parts, dies for wire manufacturing.|
Is it illegal to bring diamonds from Africa?
The Act prohibits the “importation into, or exportation from, the United States on or after July 30, 2003, of any rough diamond, from whatever source, unless the rough diamond has been controlled through the Kimberley Process Certification Scheme (KPCS)”.
Can you find diamonds in quartz?
Diamonds have a specific gravity of 3.1–3.5. Quartz has a specific gravity of 2.6–2.7. In placer deposits, tumbled quartz pebbles and diamonds can appear similar. The difference in specific gravity, however, allows panning or sluice methods to separate the two minerals.
How can you tell a diamond in dirt?
Most visitors like to dig in the soil and screen for diamonds. This usually involves searching through the first six inches to one foot of soil. Visitors can turn the soil over with a small hand tool while looking in the loose soil. Some visitors like to use a screen to sift the soil.
