How do you tell if you found a raw 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.
How do I know if my kimberlite has diamonds?
Finding large concentrations of G10 garnet can be a good indication of a diamondiferous kimberlite. On the Mohs hardness scale, garnet has a hardness of 8, compared with diamonds, which have a hardness of 10.
How do I identify my kimberlite?
Kimberlites are very diverse, but generally have distinct trace mineralogy. The only way to absolutely identify one is by thin section and chemistry. And finding a kimberlite that contains diamonds is even rarer – most do not.
How can you tell if a stone is 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.

What color is kimberlite?
kimberlite, also called blue ground, a dark-coloured, heavy, often altered and brecciated (fragmented), intrusive igneous rock that contains diamonds in its rock matrix. It has a porphyritic texture, with large, often rounded crystals (phenocrysts) surrounded by a fine-grained matrix (groundmass).
How do you separate kimberlite diamonds?
The kimberlite is extracted in enormous quantities using huge trucks and giant steam shovels; the pipe is mined from the surface as an open pit. When it gets too deep, underground mining may begin. Because of the huge quantities of rock involved, the mining is highly mechanized.
What does a diamond look like when it’s found?
Shape: Diamonds found at the Crater are typically smooth and well rounded. Their shape resembles a polished stone with smooth sides and rounded edges.

- Diamonds are rounded not edged. …
- Check for translucency. …
- Check for toughness.
What does a diamond look like from the ground?
When mined from the earth, diamonds look like cloudy rocks before they're cut and polished. Their chemical nature and structure were unknown for centuries. It was Isaac Newton's experiments in the 1600s that first suggested diamonds are made up of the fourth-most abundant element, carbon.
What is kimberlite worth?
Kimberlite has over 150 minerals and is very rare fetching prices of 50$ per gram.
What does a diamond look like when it is first found?
In other words, they have not been altered or tampered with after they were discovered. Raw diamonds look like transparent stones with yellowish or brownish tints. There are some that are colorless but these are rare.
Is kimberlite rock magnetic?
Usually Kimberlites contain magnetite as an accessory mineral. Unweathered Kimberlites usually produce conspicuous magnetic anomalies. But the weathered kimberlite is different. It loses its magnetic property considerably and becomes practically nonmagnetic, depending on the degree of weathering.

What do raw diamonds look like from Crater of Diamonds?
Diamonds found at the Crater are typically smooth and well rounded. Their shape resembles a polished stone with smooth sides and rounded edges.
How do you break open a kimberlite?
Instead of crushing the kimberlite rock, the kimberlite can simply be soaked in water (with appropriate added salts), using the internal forces within the kimberlite to break it apart.
What does a diamond look like in its raw form?
On most occasions, raw diamonds look like a collection of pale-colored glasses. You should not expect these stones to shine with their oily appearance since they are yet to be cut. Additionally, rough diamonds have a high gem quality, and only those that are very pale and colorless pass the test.
