The clue "Gem from an oyster" is a classic crossword clue that can lead to a straightforward answer. Here's how we can approach it:
1. **Identifying Key Elements**: The phrase "gem from an oyster" suggests that we are looking for something that is produced by an oyster. The most renowned gem associated with oysters is a "pearl." Pearls are formed within the shells of certain mollusks, including oysters, when they respond to irritants.
2. **Counting Letters**: When solving crosswords, it’s essential to know how many letters fit the answer. If you have a specific number of letters, it can narrow down possibilities. The word "pearl" consists of 5 letters.
3. **Contextual Relevance**: In crossword puzzles, clues may sometimes have additional meanings or require lateral thinking. However, in this case, "pearl" directly relates to the image of a gem found in an oyster, making it an unequivocal answer.
4. **Confirming with Known Letters**: If you have any known letters from intersecting answers, check them against "pearl." For instance, if you already have "P" as the starting letter and "L" as the last letter, "pearl" matches perfectly.
Based on this analysis, the answer to the clue "Gem from an oyster" is **PEARL**.
