This caught my eye as I hadn't been aware of precious gem deposits in Greenland.

No telling what may be buried under the icecap there.

Why wouldn't it be, considering that they have elves?

Check out “Ice Cold Gold” on the Animal Planet channel - American miners hunting for rubies in Greenland. It was pretty good, two seasons have aired so far.

The formation of rubies and sapphires is an unlikely event. This Discovery article from 2003 gives a description of the formation of corundum deposits in marble (metamorphic limestone). Just before this article was written, I was taken to a marble deposit near Phrae, Thailand. I was told that, at one time rubies had been found there. As the article states, these deposits were likely a result of the collision of the Indian plate with the Eurasian plate. The article goes into more detail.

TLC or Discovery did a series about some guys looking for rubies there. They found them basically just lying around and embedded in rocks on the surface. I wonder if these are the same guys or did somebody claim jump them. I think it was Iceland. Maybe it was Greenland. Anyway, there were a whole bunch of rubies there.

“Basically, ruby is a form of aluminium oxide (Al2O3), or corundum, which at nine on the Mohs scale sits just one place lower than the hardest element diamond.”

Sloppy journalism. Diamond is not an element; it is formed from carbon. Likewise aluminum oxide is not an element.

I buy gold, silver and diamonds for a living. It’s amazing how little we get for used diamonds with our wholesalers. If they are less than a 1/3 carat they bring very little. According to the best information, gem quality diamonds are as common as pearls. They bring a much higher price because DeBeers tightly controls and manipulates the market.

Rubies and Sapphires bring even less. A wise man buys one diamond in his life.
