Servers stones within the a mantle keel tend to be harzburgite and you will lherzolite, a couple sort of peridotite.
Amazingly structure
The brand new geological criteria needed for diamond creation are high pressure, highest temperature, and a supply of carbon dioxide. This type of pipelines is actually molded when magma or other thing on the mantle increase to the skin because of volcanic eruptions. Through the years, these processes establish the fresh diamond-influence rocks and then make them accessible for exploration. The value of a good diamond is dependent upon the newest greatest “4 Cs” – carat pounds, colour, clearness, and cut. Regarding the jewelry community, diamonds is extremely cherished due to their charm and you will rarity, and they are accustomed perform astonishing pieces of large-avoid accessories.
Characteristics

Diamonds be much more uncommon when it comes to large clearness gradings.
Expensive diamonds regarding the mantle form as a result of an excellent metasomatic processes where a great C–O–H–N–S water otherwise melt dissolves vitamins within the a stone and replaces them with the newest nutrients. Rather, these represent the outcome of tectonic process, even though (because of the age diamonds) not always the same tectonic processes one to work in the current. Popular rocks on the mantle for example basalts, carbonatites, and kimberlites features ratios ranging from −8 and 
osdos1dos;2. The new inclusions shaped at the depths between eight hundred and 800 kilometres, straddling top of the minimizing mantle, and supply evidence to own drinking water-rich liquid during the such deepness.
