Jewels??

There is only 2 jewels to you right??
I’m only a stone
an ordinary stone
So i walk away
i no need at a place that do not need me

I’m only exist
at a place that need me
either to help or company
but never become the sub
what’s for?

To prove that i’m useless
or i so unimportant as any other else
Only those can change the stone become diamond
Only place or people that can see my existence
can make me stay
