I purchased this and the 9mm Tungsten Celtic design ring for our 20th anniversary wedding vow renewal. We didn't want to replace our original diamond wedding rings, but wanted to exchange bands. One of the first things that caught our eye was the Celtic design, since our ancestry is Celtic. The etching, especially on the 5 mm, isn't as distinct and visable as I thought, but we are both still very happy with them. The 9 mm is easier to see, mainly because of the size difference. The comfort-fit allowed me to go down 1/2 size, while my husband stayed at his current size due to some arthritis. Both rings fit perfectly -- even in the heat with swollen fingers we had no problem getting them on or off. The price is remarkable -- I priced other Tungsten rings at area jewelers and couldn't find anything less that 3 times the amount of this ring. If you are looking for a stylish, comfortable, and very reasonably priced band, you can't go wrong with this ring.
