I saw that show too, and I also read an article about the DeBeers near-monopoly on the diamond market, and how they established it, and their advertising tactics. I think only diamond experts would know which stones are a cut above the ordinary and have real and lasting value. The rest of us are just buying into the hype.
Yep, not me anymore though. That was an interesting program. I only have one one and a quarter k diamond that was from my moms ring. That's all I want. Unless someone wants to give me the Hope diamond or something!
