Got bs ezthok weapons one with 2k kills another with 3.8 mil gold earned. Does having gems like this in the item increase the value?

idk for sure, but i cant rly imagine

I would say no

For myself I prefer clear starts on gems so I can see my own progress

This for me too.

But I think someone would pay for high stats

Why someone would pay for it?
They take a high gem, brag about it ?
The only sense I see for such a gem is u begin from 0 and see your "progress" somehow.
But it just my 2 cents
free bump

Nope, unless it's those rare one's that you can't obtain anymore.

i.e sniper dmg tower, pa arcana etc

maybe if its like a gold gem with some insanely high number only thing i could see.
