![]() ![]() A speaker dome made out of diamonds can vibrate very rapidly because this gem is such a stiff material. A diamond can also make your music sound better. Topaz clarity tumblr windows#These windows cover X-ray machines, laser openings, and vacuum chambers. Diamond windows can be made from very thin (thinner than a human hair) diamond membranes. And there are some ingenious uses for diamonds that you may find to be very surprising. These diamond-coated tools are very wear-resistant and can be used for mining, deep-sea drilling, and road construction. Small particles of diamond can also be embedded in tools like saw blades, drill bits, and grinding wheels. For example, they can be pulverized into a fine abrasive that can be made into a “diamond paste” and used for polishing other jewelry-grade gemstones. But since diamonds are the hardest known natural substance, they are ideal for industrial use. However, these man-made gems do not possess the allure and mystery of natural diamonds, so they are not very desirable in the jewelry market. Created in a lab, they are chemically and physically exactly the same as natural diamonds. In the mid-1950’s, synthetic diamonds were invented. In addition to their contributions to the scientific field, diamonds also have practical uses in society. That matter could be a clue to the origins of life on Earth! They still hope to find carbon from primordial organic matter in these special diamonds. Even more exciting than all of these discoveries is the thought of what geologists still have yet to uncover. Deep in the mantle, the materials were encased in a forming deep-diamond and then eventually sent back up to the surface by way of volcanic eruptions. This means that the materials were subducted (drawn back down into the Earth) billions of years ago by plate tectonics. ![]() In addition to Bridgmanite, they have discovered other trace minerals and elements that are commonly present in the Earth’s crust. Now that it’s been found in nature, researchers have the proof of its existence and have named it Silicate-Perovskite (or Bridgmanite). Scientists had theorized it to be an extremely common mineral that makes up to 38 percent of the Earth’s volume, but it’s been impossible to create in a lab. In addition to water, geologists have found an elusive mineral in diamond inclusions. Called ICE-VII, this water ice can only be formed under tremendous deep-Earth pressure. They have developed this idea after discovering a special water encased in the inclusions of deep diamonds. Scientists think that there may in fact be as much water present in our planet’s deep subsurface as there is found in our oceans. But diamond research has brought us closer to figuring out how much water lies deep underground. Did water come from incoming asteroids and comets, or was water an integral component at the planet’s formation? We’re still not quite sure. With these diamonds, scientists are uncovering clues to the origins of water on Earth. Unfortunately they can’t, but these super-deep diamonds are the next best thing to journeying there themselves! ![]() ![]() No doubt geologists would love to travel deep under our planet’s surface like the characters in Jules Verne’s 1864 science fiction novel Journey to the Center of the Earth. These 3.5 billion-year-old gems formed at a pressure that is 240,000 times the atmospheric pressure at sea level, and this fact makes these tiny stone time capsules extremely valuable to researchers. But there are some diamonds, called super-deep diamonds, that come from far down in the Earth’s mantle and are as deep as 500 to 600 miles (the mantle, which is mostly made up of solid and very hot rock, is directly below the Earth’s surface layer, or crust, and makes up more than 80 percent of our planet’s volume). The majority of diamonds are created fairly close to the Earth’s surface, between 93 and 150 miles down. Researchers are studying them to try and uncover the secrets of the deep-Earth environment. Topaz clarity tumblr full#But in the scientific world, a so-called “poor” specimen that is full of inclusions (imperfections), could hold a treasure trove of geologic information. In the jewelry world, a diamond with perfect clarity is the much-desired ideal. Perhaps you’ve heard the adage “one person’s trash is another person’s treasure.” Well, it just might surprise you that this saying holds true for diamonds. ![]()
