Someone who leaves no stone unturned is thorough and persistent: they look carefully, check different sources, and do not give up after the first attempt.
The phrase can describe a literal search, such as looking for a lost ring, or a figurative effort, such as investigating a complicated problem.
It does not guarantee success.
It emphasizes how completely someone tried.

How to Use the Expression
“Leave no stone unturned” commonly appears with verbs such as promise, try, search, investigate, and do.
It can describe an effort that is underway or one that has already happened:
- Present or future effort: “We will leave no stone unturned as we look for a solution.”
- Past effort: “The auditors left no stone unturned during their review.”
- Ongoing commitment: “The team is leaving no stone unturned to identify the cause.”
The idiom is neutral in tone and appears in everyday conversation, journalism, business, and formal statements.
It can sound emphatic, especially in a promise such as “I’ll leave no stone unturned.” Use it when the idea of exhaustive effort matters; for routine tasks, a simpler phrase like “I’ll check carefully” may be more natural.
Is “Leave No Stone Unturned” Literal or Figurative?
It can be either.
In a literal scene, a person might turn over stones while looking for insects or a small object.
More often, the phrase is figurative: there are no actual stones, but the person is checking every likely lead or option.
Because the idiom suggests a broad search, avoid using it when someone has only made a casual or limited attempt.
It can also be an overstatement when the task is simple.
The best fit is a situation where thoroughness and persistence are central to the point.
