Finding the Right stud-earrings for You

Stud earrings have a unique and rich cultural history. Though their design has evolved, vintage stud earrings are still a classic jewelry style.

Stud earrings are frequently dated back over 7,000 years to Asia, where they were worn mostly by upper-class men to indicate their wealth and status. Although earrings sometimes fell out of favor over the years — such as when ear piercing was prohibited by the Catholic Church in the 13th century — they’ve remained one of the most enduring forms of body modification.

When diamond jewelry gained prominence in the 19th century, thanks to prosperity in Europe and the United States as well as the greater accessibility of gemstones, studs adorned with fine diamonds became popular. Screw-back earrings debuted in the late 19th century and allowed people without pierced ears to don the embellishment. Stud earrings became especially popular in the 1960s.

Stud earrings are simple and usually small in size, making them lightweight and easy to wear. Unlike other earrings, stud earrings have a floating appearance. They are often made with a single gemstone, such as a sapphire or emerald, and a straight post that goes through the ear, typically with a rubber or metal backing to hold it in place.

Today, stud earrings accentuate outfits with a casual, elegant style, adding a bit of glam to any ensemble. Find an eclectic array of stud earrings on 1stDibs.

Questions About 2 Carat Emerald Diamond Stud
  • 1stDibs ExpertNovember 1, 2023
    Whether two-carat diamond studs are too big is a matter of personal preference. At this size, each earring will be one carat. If you opt for the classic round brilliant cut, the studs will typically measure around 6.5 millimeters in diameter, which is a little more than half the size of a dime. Find a wide range of diamond stud earrings on 1stDibs.
