I had to look this up, I had no idea, man made diamonds? That's kinda like a chinese cannondale to my wife
Diamonds are not that rare. DeBeers wants you to think so. They say you shuold spend 3-4 months salary on an engagement ring. I can't believe they want young couples to go into that much debt. DeBeers is a diamond cartel that keeps diamond prices high by controlling the market. Moissanite is almost as hard as a diamond and actually has more fire (sparkle).
There are many other gemstones that are much more rare than diamonds and much less expensive.
