Most people probably already know some of the truths conveyed in this video explaining how no one used to give their bride to be a diamond engagement ring until the DeBeers Corporation's highly successful advertising campaign promoting the "necessity." I thought for certain, early in the video, they were going to explain that originally (in ancient times, with a plain ring with no diamond) placing a ring on the woman was a sign of ownership. I thought they would have mentioned the collusion/conspiracy with the Soviet Union (Russia has billions of small diamonds they could bring to market tomorrow) to keep supply artificially tight and prices artificially high.
