I LOVE this rug!!  I can see why so many reviewers gave it 5 stars and posted so many pictures!  It is absolutely gorgeous and of very high quality; thick, soft and luxurious!  I purchased the 8-1/2 by 12 and I was hesitant to order because of the risk that the color would not be right and the inconvenience of returning a large, heavy item.  I can tell you the color is very close to online pictures.  I would describe it as a deep, jewel tone aqua, rather than turquoise, because it is more blue than green.  Some reviewers have described it as teal, if so, it is teal blue.  It is so thick and soft you are tempted to walk barefoot on it.  I don't know what the technical definition of shag is, but I would not call it a shag rug because the weave is very tight, not loose, and it has a much more formal look.  I would highly recommend it to anyone who is looking for a breathtaking addition to their home and enjoys luxury and beauty!
