Nevertheless, while purchasing diamond jewelry, especially earrings, you must not get captivated by its shine. Instead, you must take into consideration several factors.

One such consideration is the “size of the stud.”

Unlike the ring or necklace, deciding the stud size can get a bit tricky. It shouldn’t be too small, as nobody will be able to see the gem. Likewise, it shouldn’t be too big, as it might hurt your ears.

Apart from this, most jewelers will show you studs based on the carat weight, color, and clarity, making it quite challenging for you to pick the correct size.

But don’t worry! We’ve got your back!

Here are some tips that’ll help you select the right size!

Understanding Carat Total Weight

Generally, the studs are listed according to their CTW, i.e., total carat weight. It’s the weight of all the diamonds engraved in the stud. Moreover, as the earrings come in pairs, you have to understand the CTW of the single piece.

For instance, if studs are listed as 1 CTW, that means one earring pair weighs 0.50 CTW. If it’s a round stud piece, it’ll be around 5 mm in diameter. This way, you’ll be able to understand the stud size.

Selecting the wrong weight will directly affect the size chosen. So, you must pay attention to the CTW.


Color is one of the 4Cs of diamond purchase you must take into consideration. Usually, it is categorized into 3 shades/colors.

    • D to F represents colorless,
    • G to J represents nearly colorless, and
    • K-M, N-R, and S-Z represent noticeable color.

The technique to buy diamond jewelry here is pretty simple. The more colorless the range is, the rarest and expensive it is. Nonetheless, it is recommended to go with the G to J color range. The stone is generally colorless to the naked eyes, but the price is more affordable.


Inclusions or slight irregularities also impact the size and quality of the stud. It is divided into 5 parts:

    • F – IF: Flawless
    • VVS1 – VVS2: Very very slightly included
    • VS1 – VS2: Very slightly included
    • SI1 – SI2: Slightly included
    • L1- L3: Included

Generally, it is suggested to go with VS1 to L1. It is because the inclusions in these ranges are not very noticeable. Moreover, the studs are often small, so nobody will identify the inclusion even if you buy an L1 stone.

Where Will You Wear Your Studs?

Last but not least, to select the right size, you need to consider the occasion. Will you wear the studs for special occasions such as parties or weddings? Or, you’ll wear them every day? Answering these questions will help you select the right size for the studs.

As per the rule of thumb, 0.25 CTW and 1 CTW studs are good for everyday use. While for special occasions, you should get studs over 1 CTW.

Final thoughts

Diamonds are an enduring and precious investment. So, you must take into consideration all the points mentioned above while purchasing one for yourself or your loved ones.
