Fox, which comes in many natural colors, is found all over the world. Because of its long hair and distinctive coloring, its popularity depends on fashion, especially in the US. Fox is easy to ranch and was ranched extensively in the US at the height of its popularity. As its popularity waned, however, American fox farmers turned to raising mink, with the result that almost all fox today comes from ranches in Scandinavia (especially Norway), other European countries, and Russia, where it has always been fashionable. The ranching made possible the development of mutations such as silver and platina fox, that are variations of the natural colors.
Fox wears well, although it needs regular cleaning and care to keep the fur fluffy and the skins soft and supple. The price depends on the popularity, but red (the most common) fox is the least expensive, with platina and white the most expensive. Clarity of color is important in fox, as is the fullness and density of the underfur and soft sleekness of the guard hairs. Fox is also dyed high-fashion colors.
Blue fox: Blue fox is ranched extensively in Scandinavia. The color ranges from a blue brown to a real blue, as well as white with blue highlights.
Cross fox: The name comes from the distinctive cruciform marking in the head and neck region of the fox. The color is basically red fox with yellow tints, while the cross is deeper in color with the red mixed with black. Some cross foxes are silver in color and are called silver cross fox.
Gray fox: Most gray fox is American, with the best pelts coming from the northern states. It is silver gray with a slight tinge of red.
Kitt fox or corsac: North American kitt foxes are gray fox. In addition, there is corsac, which comes from Siberia and other places in the former Soviet Union. In comparison to other foxes, it has little guard hair. What guard hair it does have is yellow with white tips, although the fur tends to be short and soft. Corsac fox is less well-wearing than most other foxes.
Platina fox: The platina color was originally bred in Norway. It is a much lighter platinum color than silver fox, and the whiteness may be enhanced by slight bleaching.
Red fox: Red fox is native to every continent with the exception of South America. The best red fox comes from northern climates and is deeply furred with silky, strong texture.
Silver fox: Silver fox is entirely ranched. The fur is blue black in color with a white tip on the tail. The best silver fox is a true silver color with a black stripe.
White fox: This fox has extremely thick underfur. There may be a slight blue shade along the back of the pelt. Like all white furs, it may require bleaching to preventing its turning yellow. It is less wearable than the more common kinds of foxes, although it is the ultimate in glamor.
