Where is kimberlite found
They are found only in continental settings (none are known from ocean basins) and seem to be intimately related to the thick lithospheric keels that anchor our …Kimberlite pipes are usually found near diamonds. Kimberlite pipes, the oldest and most geologically stable portion of continents, are most likely to contain diamonds. Even though not all kimberlite pipes contain diamonds, most diamonds are associated with kimberlite pipes. In addition to containing at least 35 percent olivine, kimberlite also ...

The bedrock kimberlite source for the diamonds is unknown but has been presumed to be in northern Canada, the only area north of Wisconsin previously known to contain kimberlites. Recently, a kimberlite pipe, here named the Lake Ellen kimberlite, has been found in Iron County, Michigan.
The meaning of Kimberlite is stability. Kimberlite was called Diamond Rock in earlier times due to the presence of Diamonds. The presence of other crystals in it also earned names like Peridotite Diamond and Olivinite Diamond. Today, this Diamond-Bearing Rock is used for clarity, vitality, grounding, karmic healing, and transformation.Kimberlites are found as dikes and volcanic pipes which underlie and are the source for rare and relatively small explosive volcanoes (maars). Kimberlites in the Guyana Shield, in Venezuela and French Guyana, form thin, tabular dipping sills.

C. of industrial quality (non-gem quality) have no use and are usually discarded. D. are exceedingly rare, which is why their price is so high.Once a kimberlite pipe is found, it must be tested. The concentration of diamonds must be high enough to allow economic extraction. This means the minimum concentration of diamonds per ton (2,000 lb) that is practical. In some instances as little as 0.1 carats (0.02 grams) of diamond per ton is economic enough to mine.…
