Customers have found 1/4 carat to 1/2 carat blue diamonds and yellow & clear diamonds between 1/4 and 2 carats within our specimens worth $1,500-$4,000. Many customers find no diamonds on the surface or within the Kimberlite.Minerals such as kimberlite and lamproite float to and from streambeds and can be found in a variety of locations. Diamonds have been discovered on the surface of the earth for 95 million years. As the diamond crystal crystal rose through the magma, it may have been possible to preserve oxidation properties in the kimberlite pipe. In Crater of ...Jun 9, 2022 · Kimberlites are the primary source of economic grade diamonds. Their geologically rapid eruptions preferentially occur near or through thick and ancient continental lithosphere. Studies combining tomographic models with tectonic reconstructions and kimberlite emplacement ages and locations have revealed spatial correlations between large low shear velocity provinces in the lowermost mantle and ...

Jan 4, 2023 · Kimberlite which hasn’t been exposed to weathering, on the other hand, is known as “blue ground.” The blue ground is much harder and tougher, requiring machinery to force it to give up its diamonds. Kimberlite doesn’t form like many rocks do, as layers in the crust over a location. Instead, kimberlite is known to form kimberlite pipes.
