Just a diamond in the rough,
Is a diamond sure enough.
Far before it ever sparkles,
It is made of diamond stuff,
Of course someone must find it,
Or it will never be found.
Then someone must grind it,
Or it never will be ground.
But when it is found
And when it is ground,
And when it is burnished bright,
The ever lasting diamond is born.
Oh Teacher! disheartened, disappointed?
Never say,’I have had enough’,
The worst pupil in your class,
May be a DIAMOND in the rough.
