There is mostly synthetic corundum in industrial use and ruby lasers can only use synthetic rubies. However, natural formation are fascinating.

Yeah, they’re pretty common all around lake superior but you have to be careful where you pick them up due to various federal state and local laws.

If Corundum is over 50% red it is Ruby... all other color are Sapphire. Fine Ruby is my favorite gem.

I know what that means! I didn’t learn this latin in private school though. Mad Michael Savage (himself!) translated this for me and other radio listeners years ago. It means “Don’t Let The Bastards Grind You Down!”

Petoskey stones are pretty cool as well. They’re actually fossil coral.

I’ve been to one played out mine in marble near Phrae, Thailand. My wife loves ruby and sapphire as well. The Thais craft their local designs in gold (24 Carat). They have some spectacular jewelry.

That’s nice work. There can’t be many of those around.

I’d rather have that than jade with no story to tell.

“...but you have to be careful where you pick them up due to various federal state and local laws.”
I try to follow all of the rules, but seeing such a bunch of pretty rocks, and perhaps not knowing exactly what the rules were, would I grab just one or not? Quite the condudrum.

The Latin saying is also rendered as “Ne illegitimi non te carborundum”
(Double negative is correct in Latin, plus the second person singular as direct object).
“Semper ubi sub ubi”

A conundrum over corundum - quite understandable.
