I've given this detailed ring a 5 star rating because of the fine quality and attention to detail in its craftmanship. The mil thickness of the shank is ample and I do not feel it will be bending with my finger easily. The hallmark is well imprinted and the polished finish is great. I bought these for myself, daughter, mother and life long best friend. The quick story is, my daughter and I have always said, I love you infinity... she is now a teen and it was time that we had something to remind us daily of this sentiment. I included my mother and life long best friend and am excited to know we will all be wearing it for each other daily!
