It's been said before and is worth saying again: Diamonds are bullshit. They're not scarce, they're not valuable, and worse of all, they are not forever. Which is incredible--every comparable gem, like sapphires, rubies and emeralds, are all "forever" in that they're stable, don't rust, or degrade over time. Diamonds 1) oxidise, losing their sheen, and 2) expand at atmospheric pressure, eventually becoming lumps of coal. Does this happen fast? No, but the ad says "forever" and the competing crystals "are forever." Such a scam.
