Cashmere made with Mongolian goat wool is considered the highest quality, having the longest and most resilient fibers. Buyers should beware of counterfeit cashmere or "cashmere blends," which may be lower in price but not made of 100% cashmere. In 2016, $1.4 billion worth of cashmere items were exported across the globe.
