Same thing with engagement rings, it's just a stupid fake tradition created by DeBoers in the 1950s that costs an inordinate amount of money for nothing.

I really hope that lab grown diamonds puts that entire industry out of business.

Lab corundum is where it's at. Almost as hard as diamond (Mohs 9), but much less prone to cracking than diamond. It's available in tons of colors (most famous are blue and red -- sapphires and rubies). Lab-grown is so much better than natural that the way they identify natural is by looking for imperfections that lab versions don't have.

Oh, and diamonds burn while aluminum oxide does not.

There's no need to go broke when you can buy a superior product for less money.

		I definitely think sapphire is the best gemstone for rings given the huge variety of colors and reasonable synthetic rough prices. My only gripe is that green shades that look nice are hard to find in synthetics.
