Ice crystals
Ice crystals are solid ice exhibiting atomic ordering on various length scales and include hexagonal columns, hexagonal plates, dendritic crystals, and diamond dust.

Ice
Water frozen into a solid state, typically forming at or below temperatures of 0 degrees Celsius or 32 degrees Fahrenheit.
Liquid water is densest, essentially 1.00 g/cm3, at 4 °C and begins to lose its density as the water molecules begin to form the hexagonal crystals of ice as the freezing point is reached.
Diamond dust
Ground-level cloud composed of tiny ice crystals.
This meteorological phenomenon is also referred to simply as ice crystals and is reported in the METAR code as IC.
Snowmaking
Production of snow by forcing water and pressurized air through a "snow gun", also known as a "snow cannon".
These products are organic or inorganic materials that facilitate the water molecules to form the proper shape to freeze into ice crystals.
Anthelion
Rare optical phenomenon of the halo family.
Walter Tape, among others, has argued they are not separate haloes, but simply where various haloes caused by horizontally oriented column-shaped ice crystals coincide on the parhelic circle to create a bright spot.
Fractal curve
Magnified, that is, its graph takes the form of a fractal.
Fractal curves and fractal patterns are widespread, in nature, found in such places as broccoli, snowflakes, feet of geckos, frost crystals, and lightning bolts.
Milk substitute
Any substance that resembles milk and can be used in the same ways as milk.
The preferred base for non dairy ice creams are often coconut milk or plant cream, due to the higher fat and lower water content preventing the formation of ice crystals.
Moon dog
Atmospheric optical phenomenon that consists of a bright spot to one or both sides of the Moon.
Moon dogs are caused by the refraction of moonlight by hexagonal-plate-shaped ice crystals in cirrus or cirrostratus clouds.
Ice cave
Any type of natural cave that contains significant amounts of perennial (year-round) ice.
Although the portion of a cave within this permafrost zone will be below freezing, permafrost generally does not allow water percolation, so ice formations are often limited to crystals from vapor, and deeper cave passages may be arid and completely ice-free.
