Diamond is the hardest naturally occurring mineral, topping Mohs’ Scale of Hardness with a relative hardness value of 10. Diamond is a polymorph of the element carbon, and graphite is another.
What minerals are polymorphs?
Polymorphs are minerals with the same chemical composition but different crystal structures.
In the Earth’s crust the most abundant elements are as follows:
- O, Oxygen 45.2% by weight.
- Si, Silicon 27.2%
- Al, Aluminum 8.0%
- Fe, Iron 5.8%
- Ca, Calcium 5.1%
- Mg, Magnesium 2.8%
- Na, Sodium 2.3%
- K, Potassium 1.7%
What mineral is found with Diamond?
Diamond is a rare, naturally occurring mineral composed of carbon.

Are diamond and quartz polymorphs?
If a rock containing quartz is subducted into the mantle, the quartz transforms first to coesite at a depth of about 100km, then to stishovite at a depth of about 250km. These minerals are said to be polymorphs of quartz. Graphite and diamond are polymorphs of carbon.
What is the meaning of polymorphs?
an organism having more than one form or type as a result of discontinuous variation. Crystallography. any of the crystal forms assumed by a substance that exhibits polymorphism.
What does it mean if two minerals are called polymorphs?
Polymorphism is the ability of a specific chemical composition to crystallize in more than one form. This generally occurs as a response to changes in temperature or pressure or both. The different structures of such a chemical substance are called polymorphic forms, or polymorphs.
What rock is diamond found in?
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.
How deep can you find diamonds?
Diamonds only spawn at layer 15 and lower, and most commonly between layers 12 and 5. This is pretty deep, almost down to the very bottom of the world.
Is Diamond a metal?
Carbon is a solid non-metal element. Pure carbon can exist in very different forms. The most common two are diamond and graphite.
Diamond and graphite.
|Transparent and colourless||Opaque and black|
Are diamonds found 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.
How can you tell if a rock 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.
What is the hardest rock?
Diamond is the hardest known mineral, Mohs’ 10.
What is the meaning of polymorphs in blood?
any of a group of white blood cells that have lobed nuclei and granular cytoplasm and function as phagocytes; they include neutrophils, basophils, and eosinophils.
What is the origin of polymorph?
(1) An organism having more than one adult form, e.g. the various adult forms of social ants. (2) A granulocyte. Word origin: From Ancient Greek poly (many) + morph (form).
What happens when polymorphs are low?
What does it mean if levels are low? Lymphocyte counts below the normal range can also be temporary. They can occur after a cold or another infection, or be caused by intense physical exercise, severe stress, or malnutrition. A low level can also be a sign of a condition known as lymphocytopenia or lymphopenia.
