How do you spot a 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.
Is kimberlite hard or soft?
Rocks with hardness 1-3 are soft rocks from 3-6 are medium hardness rocks and 6-10 are hard rocks. Kimberlite cleavage is conchoidal. The specific gravity of Kimberlite is 2.86-2.87. Kimberlite is translucent to opaque in nature whereas its toughness is not available.
Do all kimberlites contain diamonds?
Kimberlite pipes were first found near Kimberley in South Africa, but since then they have been found on most continents. Of course, as has been noted, not all kimberlite pipes are created equal and only a small percentage of them contain diamonds.
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 you break 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.
How much is kimberlite worth?
Kimberlite has over 150 minerals and is very rare fetching prices of 50$ per gram.
How do you get diamonds out of kimberlite?

How can you tell if a rock is 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.
How do you know if a diamond is in soil?
Here are some tips to help you spot a real diamond:
- They do not look like the ads. Diamonds sold in stores are already cut and polished.

- Check for toughness.
