    Gold is way more difficult and complex to make, but yet Diamonds are way more expensive and rare, Gold takes the force of a Super Nova to be created, under gravity pressure close to a black hole and temperatures of millions of degrees, Gold and other metals are way more complex than Diamonds . while diamonds take only a few tens of thousand degrees and a few hundreds tons of pressure. In conclusion, Diamonds are created at the center of the earth, Gold and other metals are created with the force of a Super Nova, by the way not even the sun has the mass to create a super Nova, it's a Giant White star that has the power to do so. all the elements were created by the power of a Super Nova, a Giant white Star, our Sun is considered a dwarf white star.

    Why is the diamond’s dark side so important for its sparkle? The most compelling reason our eye is caught by the sparkle of a diamond resides in the brain. Parts of the visual cortex respond strongly to high intensity contrast edges, and so the close proximity between brightly lit and very dark facets enhances the perceived brilliance of a diamond. The visual impact is enhanced by any slight movement of the stone, which causes a dramatic flashing and different facet areas to light up and then dim.

      Marshall Ahmat I'm searching for that answer as well, I had a dream last night that I was attending a church event, it wasn't at my church and I didn't feel like I was in charge of these kids but I was dealing with some unruly children, they were cussing at everyone, very rebellious, it was like I was chasing them, and I was trying to talk to them and teach them to be more respectful. Someone that I know from church stopped me and showed me a video of a ugly black rock and when chizzled and broken away, it revealed a diamond. At that point I quit chasing them and later in the dream they had completely changed, just a thought but maybe that guidance I was trying to give to them, put pressure on them to do what was right and revealed the diamond they were meant to become? Did you find out what your teacher was trying to tell you through this lesson? Maybe you could help me and shed some light on this dream I had?

    I had a real diamond keyring, my father said it's fake, I see it shines like the real diamond, that cost 250 baht, (I'm not Thailand people, but I had a holiday here) , once I hear that compare with TVclip, I know my diamond keyring is real, cuz this shop is totally a thousand worth, it only discounted 89%.... Well... If it not discounted.. Wouldn't it be a thousand dollars?! They even sell real pearls cost 430 baht... Discounted...

    I will never forget when I saw my first Prism. I got to see the Sunlight beam into the Prism and the Prism would take the Beam of Light and it would transfer it into a Beautiful Color Band. Wow ! I was so Thrilled to see this Beautiful Color Band. Then someone told me about a Diamond, and how it is formed. This to me was a tremendous mind and heart opening of Natures Way of Forming the Most Beautiful Stones I had ever seen. Thinking of a Prism, I knew that a Diamond side by side had and shared similar Amazing Faculties and Traits. Then I learned about the actual Forming and Creation of a Diamond. Just to think, that first it must have Severe Pressure; kind of like 800 thousand pounds of weight on top of it.... Then Severe Heat, kind of like 2700 Degrees all over it. In this amazing formula: of these Two Objectivities - Causing the Crushing of Molecules together and Changing it's Molecular Structure - Permanently. Carbon into Diamond.... Because of this Beautiful Reflection of a Diamond, just like a Prism, they are Extremely Valued and Sold for a High and Very High Price in Life. Well, in Human Spirit and the Courage Men receive in Difficulties; their is a Value Here. People Buy Value in Stones, Because they See more than a Quality, they see a Longevity and Endurance and a Gift that cannot be Compared. They are Priceless ! So, We Value our Fallen Hero's of Faith for our Country. The Serviceman and Women who have gone to Battle for over 280 years and came back with scares and memories and did it for God and Country. Will You Allow God the Almighty, Creator of Heaven and Earth to " Forge You " for His Battle of Truth in our Nation - Called " America the Beautiful ".... Beautiful because, our Arm Forces shed their Blood on foreign Soil, to Keep our Soil Safe and Secure. Thank You Arm Forces for your Duty and Respect for United States of America. God Bless Everyone of You...... I Corinthians 13:1 - 10

    Steel is formed in the earth's molten core and then is shot up to the surface when a volcano erupts.

    Unfortunately not. Diamonds require very specific environments as they become unstable if the temperature is too high. It is only where the kimberlite pipe strikes the particular diamondiferous field (a certain pressure/temperature range) where it can be drawn up towards the crust where we can extract it, often in the thickest, oldest and coldest parts of the crust, which are called cratons.

    My understanding is that diamonds formed under ancient conditions that do not exist anymore and that all the diamonds we have seen are many millions of years old. But how many millions? Billions? And what was all of earth like at that time?

    It is strongly believed that diamonds are made from coals, however this is not true. The fact suggests that coals are found among other rocks like limestone whereas diamonds are found in beams nearly hundred miles under the core of earth and are brought up during outbreak of volcanoes. Although high pressure and heat is required for the formation of diamonds from carbons but these carbons are not the ones that form coal.

    Define "credible." I have a feeling that your definition and mine are very different. I think you've made up your mind and are unwilling to reevaluate your stance in spite of any evidence that I provide.
    Scientists have the capability to grow muscle tissue in a lab, does that prove that no muscle tissue comes from nature?

  • kdc43
    kdc43 6 years ago

    Well, how come NO credible person has ever found one in Nature, there is Zero Evidence for them. "Natural" diamonds are in the same category as ghosts, Big Foot and flying saucers.....TVclip is filled with wild claims of them, but there is no evidence of them OR "natural" diamonds. Psychics claim to bend spoons with the mind but scientific skeptics use tricks to do the same thing and prove psychics are fakes. Scientific Labs make diamonds and that proves all the "natural" diamonds are fake.

  • EmilyamI
    EmilyamI  6 years ago

    How long do you think we've been making diamonds in those labs? The earliest accounts of diamonds and the earliest diamond artifacts come from India in the fourth century BC. The technologies used to create diamonds in a lab has only been around since the early 1900s.
    In Crater of Diamonds State Park in Arkansas, the public can even dig up diamonds themselves.

  • kdc43
    kdc43 6 years ago

    Diamonds are mythical paranormal things like space aliens, UFOs, Big Foots and the like. There is no such thing as 'natural' diamonds because we can make real diamonds in the lab factories. I will give Money to anyone who can prove the mythical diamonds came from the ground, but you can't because they don't exist. But using Science we can make authentic ones.

    too be honest. i dont think its just russians. u cant just say its them. cause if u think: y would they do that? the answer ud get would be "money." and russia isnt the only country hu wants money...every country does to sum degree. therefore, most countries that hav the power and money to make fakes, would do it to make MORE money.

    Wow I'm actually surprised that I didn't hear naturalistic garbage such as "they took millions of years to form" in this video. Diamonds don't take anywhere near as long to form as some people think... C14 in diamonds proved that.

    @EmilyamI I mean an oyster's mantle, when particles get stuck between the mantle and shell.

  • EmilyamI
    EmilyamI  7 years ago

    @williamjpiano Pearls are formed in mollusks (like oysters) when they're irritated. A grain of sand or some object gets into their shell and they secrete a fluid that encases and smooths it so that it doesn't pain them anymore. And voila, a pearl.

  • Kulgera4
    Kulgera4 7 years ago

    @CaramelCleo I'm not an expert, but I would presume that if the carbon is crystalized correctly, there shouldn't be any difference in its strength. However, current technology is inferior to nature, which has centuries and the Earth's mantle at its disposal, therefore artificial diamonds are not as good as natural diamonds, for now. For industrial applications, today's artificial diamonds will suffice.

  • Kulgera4
    Kulgera4 7 years ago

    @ZephonTLucifer There are many uses for industrial diamonds from abrasives to cutting tools, so you can make reasonable amount of money off of it. However, it doesn't come close to the money made by the rarer, better constructed natural diamonds. At least you never hear of an artificial diamond referred to as a blood diamond.
