As an alternative, let me share an observation. People don't often change their minds right away. Specifically, there is a huge amount of neural reconfiguration which happens when we sleep, which is why we "sleep on it". The interesting question, which is impossible to answer, is how those women felt about lab-grown diamonds by the time it was important. I'd guess that nearly all of them became more open to the idea, and that more changed their minds later than had revised their opinion immediately after the lecture.
