This ring is sturdy and has a really nice weight to it. I purchased the 5mm comfort fit band. I recommend paying the extra shipping as it makes it come very fast (3-5 days) and is secure. The customer service is spectacular. The seller is quick in replying and easy to work with. I had to return my ring the first time because I ordered the wrong size. Keep in mind if you return it, you do have to pay shipping for it, but that is a small price to pay for the good quality ring and excellent customer service that this seller provides. They are very prompt in making and shipping the ring and it arrived in a very nice looking box and gift bag. My fiancé likes the ring very much. I would definitely recommend this seller to others.
