Yellow ground kimberlite is easy to break apart and was the first source of diamonds to be mined. Blue ground kimberlite needs to be run through rock crushers to extract the diamonds. [27] Mir mine. See also Mir Mine and Udachnaya pipe, both in the Sakha Republic, Siberia. The blue and yellow ground were both prolific producers of diamonds.

They are well known as the primary source of diamonds, and are mined for this purpose. Volcanic pipes are relatively rare by this definition based on minerals and depth of the magma source, but on the other hand volcanic diatremes are common, indeed the second commonest form of volcanic extrusion (that is magma that reaches the surface).
A diatreme, sometimes known as a maar-diatreme volcano, is a volcanic pipe associated with a gaseous explosion. When magma rises up through a crack in Earth's crust and makes contact with a shallow body of groundwater , rapid expansion of heated water vapor and volcanic gases can cause a series of explosions.
Small rough diamonds from Russia. Crystals are about 0.7 to 0.9 mm in size. There are a limited number of commercially available diamond mines currently operating in the world, with the 50 largest mines accounting for approximately 90% of global supply. [1]

Diavik Diamond Mine is an industrial complex set in a remote, subarctic landscape. It consists of four kimberlite pipes associated with the Lac de Gras kimberlite field and is located on an island 20 km 2 (7.7 sq mi) in Lac de Gras informally known as East Island.
