By: Elisa Bob, HSUS. Mar. 16, 2001. For years the fur industry has told the world that karakul lamb furs, also known as Persian lamb and broadtail, are simply byproducts of the meat industry.The most sought-after pelts--those stripped from unborn lambs and made into $25,000 suits--come, it says, from normal, spontaneous sheep abortions.t an auction held by Finnish Fur Sales in December 2000, more than 100,000 broadtail pelts were auctioned for between $19 and $70 each. The skin of fetal lambs is worth far more to karakul farmers than lamb chops.
One type of a well demanded fur coat is the sable fur coats. Sable fur coats are made from sables, a wild-fur bearer found only in Russia and is the most expensive fur which is valued for its lush dark color, deep silky pelt, and rarity.The sable is an animal that is native to Asia, Europe, and America, and is part of the weasel family.ussian sable fur coats are the most expensive although Canadian and American versions of sable fur coats are also available. Russian furs are really rare and hard to come by mostly because the amount of sable skin in Russia is limited, while Canadian sable fur coats are plentiful thus more economical in price.
