Genuine silk pashmina's date back to 15th Century India and were entirely handcrafted by weaving the finest silk fibers with the finest of Cashmere fibers. It is believed that that Moghul rulers of the royal court first inspired and stimulated the production of luxury pashmina shawls by bringing Turkmenistan master weavers from the fabled Silk Road to the Vale of Kashmir in India, where sericulture was widespread. Known in the Urdu language as pashm or pashmina, the finest wool fibers come from the downy underfleece of the Kashmir goats. Only this soft undercoat of Kashmir goats is true cashmere. So this fabric is true silk cashmere. Since the mid 90s, there has been a true resurgence of demand for pashmina by trendy Western shoppers all over, particularly for high-quality silk pashmina. Once again, the popularity of real pashmina is so enormous that in the last year or two, street peddlers from Vancouver, Canada to New York City have been hawking fake "100% Pashmina" fabrics that in reality are made of synthetic acrylic originating in the Far East.
