Her face is so stone-chiseled into a permanent scowl

Mrs. Biswell smiles perhaps five or six times a year, but her face is so stone-chiseled into a permanent scowl that her smile appears to be merely a tilting of the scowl.

Hi,

Is it right to take the bolded part in the above as "her face is like a stone which is chiseled into a permanent scowl?" Thanks.
