Diamond Dust - in Jewelry, Beauty Products, Art, Weather, Construction!
Diamond Dust in Jewelry - Diamond dust is somtimes used as a coating for jewelry, to add sparkle to high-end gold, silver, or platinum pieces. Many jewelers carry various types of pendants filled with diamond dust.
But the truth is in certain parts of the world -- places that have VERY cold winters -- snow will occur even though there are no clouds in the sky. Places like Anatartica, for instance. Places where the temperature drops to like -40 degrees (F), do get snow, folks!
And if there's dust or minute particles in the air on which the little water vapor there is in the air can deposit, snow can occur in temperatures like -20 degrees (F). At such temperatures, the water vapour in the air spontaneously forms ice crystals which slowly settle earthward. When these falling crystals are caught in the light, they sparkle like gemstones, a weather condition known appropriately enough as diamond dust.
Actually a very beautiful sight!
And according to a post on wikipedia: Diamond dust is often associated with halos around the sun and other related optical phenomena. These result because the diamond dust crystals form directly as simple hexagonal ice crystals (as opposed to freezing drops,) and because they generally form slowly. This combination results in crystals with well defined shapes, usually either hexagonal plates or columns. These shapes, like a prism, can refract light in specific directions. Some halos can also be seen under a cirrus cloud, but diamond dust can create much more spectacular displays because the ice crystals are all around the observer.
Diamond Dust in Construction - Last, but not least, diamond dust is used to make construction tools such as drills, and saws.
