what is the difference between Pashmina and Cashmere

Pashmina is often inaccurately described as the highest quality of cashmere. In fact there is no difference between cashmere and pashmina. The highest quality of pashmina is the highest quality of cashmere, and the lowest pashmina is the lowest cashmere. Pashmina and cashmere refer to the same thing. The raw material comes from Tibet and Inner Mongolia.
