A snowflake is a single ice crystal that is large enough to fall through the Earth's atmosphere as snow. [ 1 ] [ 2 ] [ 3 ] Snow appears white in color despite being made of clear ice. This is because the many small crystal facets of the snowflakes scatter the sunlight between them.
However, much of his recent research has focused on the properties of ice crystals, particularly the structure of snowflakes. In addition to his professional papers, he has published several popular books illustrating the variety of snowflake forms: The Snowflake: Winter's Secret Beauty (with Patricia Rasmussen photography)
This process of crystal growth is known as accretion. Crystals that exhibit frozen droplets on their surfaces are often referred to as rimed. When this process continues so that the shape of the original snow crystal is no longer identifiable and has become ball-like, the resulting crystal is referred to as graupel. [4]

A striking high detail image of rime (frost) on both ends of a column-shaped snow crystal. Again, the 24 MB ...
Nakaya Ukichoro Museum of Snow and Ice (the hexagonal building, echoing the six-sided nature of snowflakes), at Katayamazu hot springs, Kaga, Ishikawa, Japan. Nakaya was born near the Katayamazu hot springs in Kaga, Ishikawa Prefecture, near the area depicted in Hokuetsu Seppu, an encyclopedic work published in 1837 that contains 183 sketches of natural snowflake crystals – the subject that ...
The geometric shapes feature the crystal craftsmanship the brand is known for, with 133 edges to catch the light and make any tree or window twinkle. Each ornament comes in a keepsake box and ribbon.
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 ...
