To gauge size, the glass vial nearly out of frame is about 2.5 cm in diameter. (Photo: Nature Research) Close-up of purified diamondoids on a lab bench. Too small to see with the naked eye, diamondoids are visible only when they clump together in fine, sugar- like crystals like these.

On February 21, 2020, the Stanford group published their findings in an in-depth, step- by-step study in the reputed scientific journal, Science Advances. “We wanted to see a clean system,inwhich a single substance transforms into pure diamond—without a catalyst,” said the study’s lead author, Sulgiye Park, a postdoctoral research fellow at Stanford’s School of Earth, Energy & Environmental Sciences (Stanford Earth). And they did so with perhaps the least amount of fanfare in the history of inventions. From Grease to Glitz To synthesize “instant diamonds,” the Stanford research teambeganwith three types of powder refined from tankers full of aged petroleum. At a glance, the odorless, slightly sticky white powder resembles crushed rock salt, but a trained eye peering through a powerful microscope can distinguish atoms arranged in the same spatial pattern seen in a diamond crystal. It’s as if the intricate lattice of diamond had been chopped up into smaller units composed of one, two or three cages. “It’s all very fast and direct. The atoms do not pass through another form of carbon, such as graphite, on their way to making a diamond,” Park added. Oh! Those Diamondoids Wendy Mao, Stanford mineral physicist, leads the lab group where Park performed most of the experiments. Unlike a diamond, which is pure carbon, these powders—known as diamondoids—contain hydrogen. “Starting with these building blocks,” explains Mao, “you can make diamond more quickly and easily, and you can also learn about the process in a more complete, thoughtful way than if you just mimic the high pressure and high temperature found in the part of the Earth where diamond forms naturally.” ► parthdiamonds.com contact@parthdiamonds.com Direct: (310) 779-1151 Office: (213) 622-2094 Toll: 1 (855) 4 LAB GROWN 1 (855) 452-2476 All Types of Melees Fancy Shapes & Colors Next Day Delivery Extremely Competitive Pricing The Largest Lab Grown Supplier in Los Angeles Most Reputable Manufacturer of 4ct+ CVD F-J Color Rounds Up to 5ct in Every Shape and Color
