What was said about De Beers

  • De Beers made the diamond the default engagement ring with one line. Mary Gerety's 1948 line, 'How can you make two months' salary last forever?', is the copy behind 'A diamond is forever'. About 85% of engagement rings are now diamonds, and Harry Dry credits this campaign.

    The line reframes a purchase as a lasting commitment rather than a luxury. Harry Dry uses it as a copywriting example, and the 85% figure is his attribution to the campaign.
