I recently bought myself a platinum wedding band from Dellafora. I wanted something simple to wear during the week as I love my engagement ring, but it makes me nervous to wear it on a daily basis. Dellafora offered affordable options and fulfilled my order fairly quickly. Both times, it was closer to seven days to get my order filled, which is totally reasonable (IMO) since I had my wedding date inscribed. I would recommend that you size up slightly when ordering a basic band. My engagement ring is 5.25 and fits perfectly - I ordered the same size, assuming the band would be the same. It felt too snug, so I returned my original order and went up to 6.25 because I wanted a casual/loose fit to this band.
Dellafora return service was super responsive and helpful in quickly getting my first order returned and replaced for the right size.
