Do All Women Want Diamonds?
"Women want diamond engagement rings; it's a universal female desire."
The diamond engagement ring tradition dates to a 1947 De Beers marketing campaign ('A Diamond Is Forever'). Before 1939, fewer than 10% of US engagements used diamond rings. Modern preference research shows only ~40% of Gen Z women cite 'diamond' as their preferred engagement stone. The 'all women want diamonds' framing is a remarkable case of a constructed cultural norm treated as biological fact.

Where it came from
The diamond engagement ring as universal tradition is one of the most successful marketing campaigns in history. N.W. Ayer's 1947 work for De Beers — credited with coining 'A Diamond Is Forever' — created the association from near-zero to dominant in 40 years. The 'all women want diamonds' framing is downstream of that campaign.
What this means
This stereotype is unique in the catalog for being transparently constructed and documented. Its persistence is itself a case study in how marketing can become 'natural preference.' Modern preference data shows the cultural norm is already breaking down.
