No, I haven't.
Well, I guess this answer should be deleted as well, but the Admindictator is too lazy at the moment.
O my goodness, YES! All the time - whoooo, they are the BEST!
I don't purchase diamonds because diamonds in themselves aren't worth what they actually are.
Here's why diamonds are a rip off:
1. The only reason why society likes diamonds is because of a successful marketing campaign that began in 1938. It is not actually the best or prettiest gemstone as tradition would have you say.
2. In fact, a cheaper gemstone, which is similar to diamonds in hardness, actually is rated as a finer gemstone with more shine, it is called Moissanite. It is brighter, more lusterious, and has more fire than a diamond. The Moissanite industry, because there isn't large and overrated demand for it, the industry is less corrupt. Here is an image of a labratory test comparing the brilliance of these two gemstones:
3. It is not a financial-wise decision. Selling diamond jewlery you've already bought, you will not get anywhere near the price you paid for it.
4. They're literally just pretty rocks.
Nope never have and never will.
No, and the evil DeBeers cartel never got my money either -- my wife's engagement ring is an heirloom. The only sane reason to ever buy diamonds is on cutting and grinding tools.
