These Joyla gemstone stud earrings are super easy to use. Just simply insert the post through your earlobe and secure the back. They're great for everyday wear, like when you're going to work, out with friends, or to a special event. When it comes to care, avoid wearing them while swimming or doing strenuous activities as the water and chemicals can damage the gold plating and gemstones. To clean them, use a soft, dry cloth to gently wipe the surface. You can also use a mild jewelry cleaner if needed, but make sure to rinse it thoroughly and dry it completely. Store them in a jewelry box or pouch to prevent scratches and keep them looking their best.
