The hierarchy of the solid geologic masses we find within ourselves, and then pass through:
I am not an expert, but my friend, who professes to be one, assures me that crystals are somewhere near the apex. My friend also mentions gravel, but isn’t that more of an aggregate in the pedestrian sense?
A boulder, a rock, a stone, a pebble, or sand...
Diamonds and crystals somehow fit in, somewhere in the middle. Right?
Each would be painful to pass, but some are worth more than the others at the receiving end.
Your photo of the stone, or whatever, was zoomed in on a $1 bill; so I’m guessing you do not value it particularly highly?!?. Less than $1, perhaps?
My assumption is that it wasn’t a diamond you passed?!?
If the next stones that you suffer through shine back in emerald green or ruby red, give me a call.
Just kidding, internal stones, even semi-precious stones are incredibly painful.
