Diamonds are not rare at all, especially when comparing them to real rare stones.
I know the guy who discovered the deposit of rainbow garnets in Japan. I had one from him last year that he had faceted, he has a lot of them, and it was incredible.
While I appreciate fossils, I haven't really gotten into them yet. It's a whole other world to work in besides gems & minerals. I know I will some day, just need to dig some up I guess then get bitten by that bug. Have you dug up many?
Maybe some day we can go hit Rapid Creek Yukon. Another friend of mine went mining there and brought back incredible lazulite, wardite, childrenite and tons more minerals. You gotta take a helicopter into the locality though.....
