"My experience with BN has been nothing but positive, ordering both an engagement ring and a wedding band. Their prices are orders of magnitude below high street shops (which generally operate at a 300% profit margin, something BN clearly do not). The engagement ring was a custom (i.e. I chose the stone and the band separately) and arrived very quickly, just as described and was about £75% cheaper than a high street equivalent from a well known jeweller.
I've had to return the band twice due to me not getting the size right. The first time I wore it for a couple of weeks before deciding that it was just too big, and they accepted the return with no quibbles. They sent a replacement, which I found too small, which has been sent back and they are sending out the replacement again (all for free other than my costs to return the rings to them).
I have found their service to be great all round. I simply cannot relate to any of the negative experiences on here, although frankly, leaving a 1 star review due to a delay for a resize is ridiculous. Either these people are entitled ignoramuses or there is something fishy going on."
