Diamond Stud Earring Sizes:
From Delicately Demure to Luxuriously Opulent

Diamond stud earrings are a timeless and elegant piece of jewelry that can add anything from a bit of polish to your daily look to maximum glam when you’re looking to really stand out. Generally, diamond stud earrings are sold by carat weight which can make it hard to visualize how they will look on your ear if you’re unfamiliar with this type of sizing. In this blog post, we will discuss the common carat weight sizes for diamond stud earrings, show you how each looks on the ear, and suggest a few accessories that pair well with diamond studs.

Diamond Stud Earring Basics

The first thing to know is that diamond stud earrings are typically sold by the carat weight per pair. Therefore if you’re selecting a 1.00 carat weight option, each earring will be approximately 0.50 carat. Be sure to read the description of any diamond stud earrings you are considering to verify. Understanding carat-weight sizing ensures that what you order is exactly what you envisioned!

The second thing to know is that diamond stud earrings can come in a variety of settings, the most common being the prong setting, and for good reasons. This type of setting allows for maximum sparkle thanks to the abundance of light that can reach deep into the stone. At Identity Diamonds, we offer a modern, “cocktail-style” 3-prong diamond stud earring and a classic, “traditional” 4-prong diamond stud earring.

Carat weight refers to the size of your raw diamonds as measured in carats. From the technical side, 1.00 carat is equal to 200 milligrams, but that probably doesn’t help you understand the actual size of the stone! So we have a handy visual chart below showcasing some of the most common diamond stud earring sizes!
