This is great. I've heard of lab-grown diamonds for over 10 years now (and they've been making them longer than that). If the diamond market gets shook up over time, which I believe it really should, I hope the engagement ring market also gets a little shook up, which would be good too. It might encourage people to branch out a bit and look at other interesting and cool gems, like emerald, ruby, sapphire, and many others. The whole De Beers "Diamonds are forever" advertising from the mid-1900s is all bullshit anyways and yet managed to successfully brainwash generations of people into buying diamonds for their engagement rings. It wasn't always that way!
