Mauve and other colours cashmere handwoven scarf

Can you tell the difference between wool and cashmere?   I have hand-woven a fine, mauve dominant, multicoloured yarn thinking it was wool but having completed it I am tempted to say it is cashmere.  It's a left-over from a previous project which I can't recall and it is not hand-dyed like most of the cashmere yarns I have used.  But its fineness, lightweight and tendency to felt during washing suggests to me its cashmere.
However, a beautiful soft luxurious scarf of 1720mm x 200mm and weighing 84g for some lucky person.  Suitable for man or woman.  Maybe this one I  will keep for Aspects of Kings Park or The Artisan Store Fremantle.
