Are they the same?
Quartzite is found in the nature as the rock form.
The colors are, some light brown, and some transparent.
Silicon dioxide is a powder, its color is white.
What is a silica?
Is there available a picture/image of a silica?
I have a mix of rocks such as below image:
What kind of rocks are they?
She says it was found in the nature.
I doubt it because the shape, like was shaped by the hand.
It like a synthesis then shaped by the hand.
What is the chemical composition?
I will crush them using the stone crusher machine.
I doubt the form will be a powder instead of more rough than a powder.
How do I make it to be a powder?
How many times to be crushed so that the form will be a powder?
What equipment do I need to make it as a powder?
Or what chemical additive to be used to make it as a powder?

silica = silicon dioxide
You can't tell chemical composition from just a photograph.
Smooth stones form can form as a result of erosion by flowing water.
