To travel from the upper mantle to the Earth’s crust, they have to hitch a ride with a volcano, kimberlite volcanoes, to be specific. The gemstones are brought to the Earth’s surface by explosive volcanic eruptions. (public display, Carnegie Museum of Natural History, Pittsburgh, Pennsylvania, USA). These conditions allow the carbon atoms to bond correctly rather than becoming crummy old graphite. To be precise, it takes 725,000 pounds per square inch of pressure and a temperature of 2200 degrees Celsius to create the gemstone. It takes a lot of heat and pressure to form diamonds. Thus, the process is not consistent due to changes in environmental conditions.ĥ. The process is hard to clock as it may take longer for diamonds to grow or take as little as hours. No one knows how long it takes diamonds to form underground as mined diamonds are ancient, probably billion years old. When they bond tetrahedrally, they create rigid three-dimensional crystals of unmatched hardness.Ĥ. With the immense pressure and heat far below the Earth’s surface, a single carbon atom forms chemical bonds with the other four atoms. The other 0.05 percent can include one or more trace elements, which are atoms that aren’t part of the diamond’s essential chemistry. Diamond is the only gem made of a single element: it is nearly 99.95 percent carbon, the commonly found element on the Earth. The Romans also believed that cupid’s arrows were sloped with diamonds, explaining the earliest relationship between diamond and romantic love.ģ. The ancient Greeks and Romans supposed diamonds to be were tears from gods or splinters from falling stars. We require thirteen such holes to reach the prime depth of diamond-making.Ģ. The most bottomless hole to have been drilled only made it to about 7.5 miles. Mined diamonds from below the Earth’s outer crust are approximately 100 miles deep in the upper mantle. It is no secret that diamonds come from underground, but many people are unaware of how far underground.

Below are the amazing facts about diamonds that you should know.ġ. Today, a diamond is still a symbol of love, making it an ideal present for special celebrations, birthdays, and anniversaries. Moreover, the gem remains remarkable for having been around even before the age of dinosaurs. It is fascinating how diamonds can captivate one’s heart in a matter of a few seconds. Diamond sales shortly went up by 55 percent - boom.Over the years, diamond has remained to be among the top spectacular gemstone of all time.

They also realized they had to convince women that diamonds were an "integral part" of their relationships. De Beers knew they needed to make those men believe that diamonds were a "gift of love." The bigger the diamond, the greater act of love. In the 1940s, young men bought about 90% of the engagement rings on the market. Ayer's strategy plan (via The Atlantic) described how they wanted to "strengthen the tradition of the diamond engagement ring" and make it a "psychological necessity." They set out to conflate diamonds with romance. This was all part of the plan to dupe Americans into buying diamonds as opposed to other gems. In just one year's time, "A Diamond Is Forever" became the official slogan of De Beers, the most powerful diamond cartel at that time. Naturally, that information wouldn't make it into the ad. Despite their hardness, diamonds can become discolored, chip, and even shatter.
