How do you straighten a crooked ring?

To straighten a crooked ring, you can use a ring mandrel, which is a tapered tool designed for shaping rings. Gently tap the ring with a rubber mallet on the mandrel, moving it around the mandrel until it regains its shape. If the ring is significantly bent, consider visiting a professional jeweler for assistance to avoid damaging it. Always handle the ring carefully to prevent further distortion.
