Diamond Stud Earring Size Guide: Finding the Perfect Pair
Few pieces of jewelry are as timeless or as versatile as a pair of diamond studs. Refined yet effortless, they’re the kind of piece that complements every look and occasion. At Fiametta, we believe that choosing the right size isn’t just about carat weight - it’s about finding the balance between everyday ease and your signature shine.
Understanding Diamond Stud Sizes
Diamond stud sizes are typically measured in total carat weight (ctw) — the combined weight of both stones in the pair. For example, a 1.00 ctw pair means each diamond is approximately 0.50 carats.
Our Martini Studs, crafted from solid 14k recycled gold and set with lab-grown diamonds, are engineered for both brilliance and comfort. The tapered three-prong “Martini” setting allows light to enter the stone from every angle, creating exceptional sparkle while resting close to the ear.
The Size Spectrum
When it comes to diamond studs, every carat size carries its own personality — from subtle everyday radiance to statement brilliance. Below, explore how each size looks when worn.
