Tanzanite Snowflake 2010 Proof Silver Coin 20$ Canada 2010
Snowfall is an incredibly spectacular phenomenon, and quite a strange one. Depending on weather conditions, small ice crystals can form different flake shapes. Some Eskimo tribes have 9 names for different kinds of snow. The coins united in the popular Snowflake series issued in Canada depict probably the most fascinating form of snow that appears in nature – a six-side star. Scientists also call these flakes “fractals”, which means their form repeats itself, like it happens with tree branches.
