Diamond Stud Earrings
A simple size-and-scale reference for diamond studs so you can choose the look that feels right for your everyday wear.
These 14K Gold Lab-Grown Diamond Stud Earrings are classic, minimal staples designed for daily sparkle. Each pair features a clean 3-prong setting with a comfortable post, made to sit bright and balanced on the ear.
Available in 14K yellow gold and 14K rose gold with the same polished finish and setting style. (If you add a 14K white gold option later, it is typically finished with rhodium plating for a brighter white tone.)
Hand-selected by Haejin Jewelry in Williamsburg, Brooklyn, each pair is chosen for its clean proportions, comfortable wear, and modern Brooklyn sensibility.
