The Diamond Stud. Tasteful. Timeless. It’s the little black dress of jewelry: From wedding dresses to jeans and T-shirts, a pair of impeccable studs go with everything, and always will.

If you’ve read our blog on diamond grading, you’ve already got some information at your disposal, which is great. But if you’re in the market for a new pair of studs, there are some specifics you should keep an eye open for. Let’s take a closer look:

Shape

This one’s up to personal preference. Some people prefer the timelessness of a round cut; others the classical appearance of a princess; and some like to think outside the box with a marquis or pear treatment. Whichever the case, don’t be afraid to go with the one that speaks to you.

Cut

 As we’ve said, cut and shape are two completely different things. Make sure you opt for diamonds that are cut exceptionally — it may be the most important quality the diamond possesses. An imperfectly cut diamond will appear flat and lifeless, while a perfectly cut stone will flicker and sparkle even under the most minimal light.

Color

We’ve mentioned before that diamond grading, when it comes to color, is on an alphabetical scale, with D being flawless, and with a yellowish tinge creeping in once you get to J, and beyond. Instinct says to splurge on the clearest diamond possible, and that’s a good choice, but a lot of experts agree that a diamond that comes in at the G-H range will appear colorless to the naked eye, and tends to be a better value than higher-quality stones.

Clarity

Inclusions, imperfections in the stones, whatever. Every diamond is different, and each possesses its own fingerprint. Sometimes, these flaws are nearly invisible; sometimes, they can be seen with the naked eye. Whatever the case, take a close look: if you can see any flaws without a magnifying glass or a jeweler’s loupe, move along. This is an investment that will be in style for your entire life, and you’re going to want a pair you can be proud of for decades.

Carat Weight

Size is important in choosing a pair of studs, but bigger isn’t necessarily better. For some, 1/2-carat is the perfect size; for others, 2 carats is ideal. It’s just a matter of how it fits on your ear, and how the size balances out. Trust us: when you get the right size, you’ll know it.

Fit

Beyond the stones themselves, the setting is very important. Always try on a pair of studs before purchasing, and make sure that the setting makes sense with the shape of your ear, and the placement of the piercing in your lobe. All settings are not created equal.
