> Diamonds aren't worth what you have to pay for them (try re-selling a diamond)
If you buy a complete ring, you're usually getting quite ripped off. But if you buy a stone, complete with its certificate, it shall be worth what the market says it is worth. Competent jewelers will have no problem with you coming with a stone you bought or with an old family heirloom stone and put it on the ring you want: you'll pay his hours and the material for the ring but that's it. And the stone is worth its market price.
Diamonds above a certain size (whether they're natural or synthetic) are engraved now. You keep the certificate and you'll be able to resell it.
You can buy synthetic diamonds, they're cheaper than natural ones. And there's also a market for these.
Note that I'm not saying that the market ain't going down. What I'm saying is that you can definitely buy a stone at its market price and resell it at its market price. That's how the markets do work: be it stocks, gold or diamonds.
