On the Mohs Scale of Hardness, Diamond is the ultimate"adamant" -- with a Mohs rating of Ten (10).
But, Magnetite (which [I know] can be scratched by a steel knife) has a Mohs rating of only Five (5) to Six (6)!

AHA! The Mohs Scale of Hardness was developed in 1812 -- considerably later than the period of linguistic confusion...

Your sweet. Well I love 82 year old coots. I happen to be married to one for the past 32 years. He married me when I was a baby though. He is 26 years old than me. He still climbs deer stands. I think I have finally convinced him age is a state of mind. I keep him young.
The stuff on lodestone was cool huh!
Q says there are double meanings so it is just smart to consider something from many angles.
