Falling diamond dust (Inari, Finland) Diamond dust is similar to fog in that it is a cloud based at the surface; however, it differs from fog in two main ways. Generally fog refers to a cloud composed of liquid water (the term ice fog usually refers to a fog that formed as liquid water and then froze, and frequently seems to occur in valleys with airborne pollution such as Fairbanks, Alaska ...
Ice crystals create optical phenomena like diamond dust and halos in the sky due to light reflecting off of the crystals in a process called scattering. [1] [2] [15] Cirrus clouds and ice fog are made of ice crystals. [1] [16] Cirrus clouds are often the sign of an approaching warm front, where warm and moist air rises and freezes into ice ...
The sublimated gases carry micron-sized dust grains to form an observable coma and tail during their perihelion passage. Infrared observations show that many JFCs exhibit a debris trail of up to cm-sized particles along the comet's orbit. [95] When the Earth passes through a comet trail a meteor shower is observed.
Recent studies suggest that injecting solid particles into the atmosphere may significantly mitigate stratospheric warming. The study’s findings also underscore the uncertainties surrounding the ...
Lab-grown diamonds of various colors grown by the high-pressure-and-temperature technique. A synthetic diamond or laboratory-grown diamond (LGD), also called a lab-grown diamond, [1] laboratory-created, man-made, artisan-created, artificial, synthetic, or cultured diamond, is a diamond that is produced in a controlled technological process (in contrast to naturally formed diamond, which is ...
When CO 2-V is subjected to high temperatures, or higher pressures, experiments show it breaks down to form diamond and oxygen. In the mantle the geotherm would mean that carbon dioxide would be a liquid till a pressure of 33 GPa, then it would adopt the solid CO 2-V form till 43 GPa, and deeper than that would make diamond and fluid oxygen.

These include the Western Diamond-backed, Mohave Desert Sidewinder, Colorado Desert Sidewinder, Southern Pacific, Great Basin, Red Diamond, and Panamint rattlesnakes.
In detonation synthesis, nanodiamonds form under pressures greater than 15 GPa and temperatures greater than 3000K in the absence of oxygen to prevent the oxidation of diamond nanoparticles. [10] The rapid cooling of the system increases nanodiamond yields as diamond remains the most stable phase under such conditions.
