De Beers' new campaign material focuses on the statement 'I do', as one of the most significant and time-honoured expressions of intent.

"De Beers’ new campaign emphasises the importance of these powerful commitments, and takes these two iconic words into new territory, expanding their meaning to stand for personal pledges of all kinds: to love, friendship, family, society, nature and more."
