Neutrons have anti-neutrons.Kimberlite is a volcanic rock containing isolated pieces of rock or crystal that were pushed up out of the earth's mantle by magma. Kimberlite can be identified by its fine-grain texture, its blue or yellow color, and/or the presence of diamonds and other gems in the rock.Deep blue and vivid blue diamonds cost much more—around $75,000 for a 0.25 carat diamond.

Gem Encyclopedia Gem Encyclopedia Gem Encyclopedia Birthstones GIA's Gübelin Gem ProjectDiatreme. 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. Kimberlites show two distinct modes of emplacement, each resulting in characteristic textural and mineralogical differ - ences.
