I originally researched this from 2 different direct sources, which gave the different gram weights and prices for each rug.  Didn't like the samples I got from one source.  Then I saw THE rug at Wayfair.  Cheaper than going direct and free shipping.  No gram weight was listed, and it was about half the weight of other sources.  No problem--it was PERFECT.  Texture, fit, care instructions, price--all a home run.  Love it.  I will use Wayfair for all home dec needs.  Thank you.
