A gold stud earring is a simple yet elegant piece of jewelry that typically consists of a small, often round or square, gold piece attached to a post that goes through the earlobe. Here are some key features and details:

• Material: Usually made from solid gold (like 14k or 18k) or gold-plated metal, giving it a shiny and luxurious appearance.
• Design: The design can range from minimalistic (plain gold) to more intricate styles featuring patterns, engravings, or gemstones.
• Size: Studs can vary in size, with small ones often around 3-5mm in diameter, while larger ones can go up to 10mm or more.
• Backing: Most stud earrings come with a secure backing (like a butterfly clasp or screw-back) to ensure they stay in place.
• Versatility: They are suitable for both casual and formal occasions, making them a staple in many jewelry collections.
