At least to my eyes, the pictures and the description as being "half-round" suggested that there was considerable "radius" to the band. But the band has only what seems to me to be a normal amount of thickness relative to the 8 mm width. [Measure it at 7.8 mm with a digital caliphers] Compared to the 7.8 mm width, the thickness is only 2.5 mm, so it's clearly not "half-round", which would be 3.9 mm. And yes, it is somewhat darker that the picture, but it is highly polished and reflective, so it's not really "dark" per se.
