How to Shop for Diamond Jewelry

Whenever you shop for anything with diamonds, it is essential to remember the four Cs.

These are guidelines established by the Gemological Institute of America (GIA). They consist of the following attributes that impact the diamond quality and price.


A diamond carat is a unit of measurement that refers to how much a diamond weighs. These carat weights have a direct correlation with the size of diamonds.

Generally speaking, the heavier a diamond is, the bigger it will appear to the eye. That being said, there are ways to make diamonds look bigger than their carat weight would indicate.

Within the context of earrings, total carat weight indicates the combined weight of the two earrings. The carat total weight of a pair of earrings is denoted with the letters ct. tw.


Cut and shape are often used interchangeably, but the two significantly differ.

A diamond’s cut refers to how well the diamond was cut and polished by a gem cutter, whereas the shape describes the face shape or form of a diamond (round, pear, emerald, etc.)

The cut determines how brilliant and sparkly a diamond will be. That is why choosing diamonds with a high-quality cut grade is important, as you don’t want a dull diamond.


Clarity is how many imperfections or blemishes a diamond has. However, even a diamond with slight marks or blemishes will still appear relatively clean when looking at it without any specialized equipment.


The diamond color refers to the absence of color within a diamond. Colorless diamonds are the rarest and most sought-after since they are considered the purest.

Most natural diamonds have a slight tint of yellow or brown color, but if you get a near-colorless diamond, you usually won’t see this tint with the naked eye. This is a good alternative to colorless diamonds for those on a budget.

Popular Shapes for Diamond Studs

Round diamonds are the most popular shape overall, not just for stud earrings.

Round diamond studs are perfect for those looking for simple yet sophisticated elegance. They are a classic that never goes out of style.

Asscher cut diamonds, Emerald cut, and other rectangular-shaped diamonds are also popular shapes for stud earrings.

These diamond shapes offer a larger-than-life shine to your earrings, making them appear larger than their carat weight. Rectangular stud earrings make an impression and stand out wherever they go.

What Is the Most Common Diamond Stud Earring Size?

There are many different stud earring sizes, with the majority in the 0.25 – 2 ct. tw. range, as shown on the stud earring size chart above. Most people who buy diamond stud earrings opt for a 1 ct. tw. This particular size also provides a great balance between noticeability and versatility.

Another reason 1 ct. tw. stud earrings are a popular choice for buyers because they are affordable. They are big enough to add a significant sparkle to any outfit and practical for everyday wear without a heft price tag.

For these reasons, 1 ct. tw. diamond stud earrings are the most widely available in various settings and styles.

How Big Should Diamond Earrings Be?

Regarding what size diamond stud earrings you should buy, your personal preferences and budget are the most important factors.

However, a good size for everyday wear stud earrings is anywhere from 1/2 ct. tw. – 1 ct. tw. Stud earrings with a 2 ct. tw. are more suitable for special occasions where larger studs are desired.

You also want to keep in mind your face shape and the size of your earlobes when choosing a size. Smaller stud earrings are recommended if you have a smaller face or petite earlobes. The opposite is true for those with more prominent features.

Lab Grown Diamonds vs. Natural Diamonds

If you want to purchase a pair of stud earrings, consider the benefits of lab created diamonds. Not only are they physically and optically the same as those grown beneath the Earth’s surface, but they do not hurt the Earth.

If budget is part of your buying decision, you might hesitate to choose the larger carat. Luckily, lab created diamonds tend to be anywhere from 20-40% less expensive than mined diamonds. So, what does that mean for you when you’re buying diamond earrings?

It means that for the same price as mined diamond studs, you can get a pair of lab-grown diamond studs that are 20-40% larger. Not only can you get the carat size you want, but you can also walk away from the purchase knowing that you went with the diamond option that is both green for your wallet and ethically sourced.
