Sable (Martes zibellina) is a small mammal, closely akin to the marten, living in southern Russia near the Ural Mountains through Siberia and Mongolia to Hokkaid?? in Japan. Its range in the wild originally extended through European Russia to Poland and Scandinavia. It has achieved fame for its fur, which is integrated into various clothes fashions (for example the shtreimel). Sables range in color from tan to black, black being the most prized. The top grade of black sable fur is called "black diamond".

I don't know where this is from, since the original poster didn't show any copyright info either.
