Not available

Explanation:

Green gemstone" is a straightforward definition clue pointing to peridot, a bright green mineral often used in jewelry. The word itself comes from the Arabic faridat, meaning "gem," and it’s known for its olive-green hue. No wordplay here—just a direct hint at a well-known stone, sometimes called the "evening emerald" because it keeps its color under artificial light. If you’ve seen August’s birthstone, you’ve likely seen peridot.
