Nice theory, but I don't think it's true. My parents or grand-parents, or great-grand-parents never had a diamond ring. Who could afford a diamond ring until the 1960's, except the very rich ? I don't think it is more common now, because many young couples don't even get married these days. It is more of an American phenomenon. That's why it is also common in Japan or South Korea, but not really in Europe. Consumerism has never worked very well in Europe.
