Almost anyone who has had an ear pierced knows what a stud earring is. You remember that first earring...a simple birthstone or gem in the shape of a circle at the end of a post? It came shooting through a gun, pierced your ear, and you thought it was the prettiest thing you’ve ever seen (after the pain faded away)! The all-grown-up version of that is the diamond or pearl stud earrings, perfect for adding a touch of glam to everyday wear when you want to plus up your look without adding a dangle anywhere. Studs come in many shapes—circle, heart, square, pear, snowflake, stars and more. This versatility in shape, material and color is what makes them so suitable for just about any casual outing, and even for an understated look for formal wear. While there are many fancier types of earrings out there, the stud is a great choice when you’re in a pinch for time and just need to finish off your look and head out the door in a rush.
