The Original and Rare Diamond Stones Are Derived From Earth Mantel

Recently found the original diamond stone research results GIA scientist team, diamond stone size is remarkable and its quality can reveal new clues about the geology of the Earth. The scientists studied the unique properties of these diamonds with characteristics similar to famous stones, such as Cullinan, Constellation, and Koh-i-Noor.

This study aims to advance the understanding of the earth's deepest mantle, where secrets are hidden beneath tectonic plates and largely inaccessible for scientific observation.

Fact, Genuine Diamond Stone In Extreme Depths###

This new discovery has helped solve one of the major puzzles in diamond formation studies, namely; how the largest and most valuable original diamond stone in the world can be formed. These observations have broad implications, including to understand the behavior of Earth's mantle, recycling surface rocks into the mantle, rock storage, carbon cycle and hydrogen in Earth's mantle.

Dr. Wuyi Wang said, some of the biggest and most valuable diamonds in the world such as Cullinan or Lesotho Promise, describe different sets of physical characteristics. This makes a lot of people think that the original diamond stone apart from the other. How diamonds in the Earth mat are formed, and what kind of corroborating evidence about the contents of the earth remains a mystery to this day.

genuine large diamond stones such as Cullinan have a set of physical characteristics that distinguish them from other diamond types. Research shows Cullinan gems sometimes have little metal inclusions, or internal characteristics trapped inside them. Metallic inclusions coexist with traces of methane and hydrogen fluids. In addition to metallic inclusions, some exceptional original diamond stones also contain mineral inclusions.

This proves that diamonds form at extreme depths, probably depths of 360 to 750 km in the mantle. It turns out that this original diamond stone can only be found much deeper than other diamonds that form beneath the continental tectonic plates, generally at a depth of 150-200 km.###

Metal inclusions are mixtures compacted by iron, nickel, carbon and sulfur minerals, also containing methane and hydrogen liquids in a small thin space between metal and diamond phases. Pure carbon crystallizes in this mixture, the liquid metal melts inside the earth's mantle and then forms a diamond. Small droplets of metal fluids are sometimes trapped in diamonds during formation. During cutting and polishing, parts of 'ordinary diamond' containing inclusions are often disconnected or lost after polished gem craftsmen, so the drawbacks can be covered and look beautiful.

The theory of stone stitches explains that for years parts of the inner mantle (depths of about 250 km) contained ferrous metals and limited oxygen, in which metallic inclusions, methane and hydrogen, would wrap diamond stones. But scientists still have not confirmed the extent to which the role of metal to the formation of diamond stones.
