To determine if stud earrings are real gold, you can look for a hallmark stamp indicating the karat weight, such as "10K," "14K," or "18K." Additionally, you can perform a simple acid test using a gold testing kit, which involves scratching the earrings on a testing stone and applying acid to see if the mark remains unchanged, indicating authenticity.
