Things to Consider When Buying a Diamond Stud Earring

Mined or Lab Grown Diamonds?

This is the first question that comes to mind, and to answer it I need to clarify a few things. First, mined diamonds are created over billions of years and are obtained by mining the earth. On the other hand, lab grown diamonds are created in a controlled environment inside a laboratory, and are obtained after weeks or months. Mined diamonds are composed of almost pure carbon, and the composition of lab grown diamonds is exactly the same. Therefore, it cannot be said that they are fake; they are not made of plastic, glass or any other component, lab grown diamonds are made of carbon just like mined diamonds.

If you choose mined diamonds, you should know that the diamond you choose is the result of millions of years, produced by nature, and that makes it special. But you also need to know that there are conflict diamonds, diamonds often linked to serious human rights violations, forced labor and child exploitation in Africa, and are illegally traded to buy weapons. Also, these diamonds cause serious environmental damage during their extraction.

Meanwhile, lab grown diamonds don’t cause environmental damage, and you know that by buying them, no one’s rights were violated. The fact that they are created much faster than mined diamonds and that there are fewer intermediaries in the process makes them significantly cheaper.

In the past, lab grown diamonds like today didn’t exist. Those on the market were of very poor quality or were imitations. Now, there’s no difference to the naked eye between a mined and a lab grown diamond.

Types of Settings

There are three common settings for a stud earring. The first is a prong setting, where claws are holding on to the diamond. A prong setting makes the diamond sparkle more because it allows more light to hit the surface. Secondly, with a halo setting, there is a diamond in the center with tiny diamonds surrounding it giving a very elegant look. Finally, the bezel setting, where metal surrounds the diamond. This is considered one of the most secure settings.

The Back

With stud earrings, the back matters. The majority of people who want stud earrings are looking for comfort and simplicity, and for some that means a piece of jewelry that’s easy to put on and take off and, most importantly, a pair of earrings that won’t fall out. Typically there are two types of backing: push and screwback.

Pushback: The most classic earring style, this back usually has a butterfly shape that slides onto a straight earring post and presses onto the back of the earlobe. It’s a comfortable choice for everyday studs. If you want a stud earring easy to put on and take off, this is what you want to look for.

Screwback: With screwbacks, the post has the shape of a screw. The back twists on the earring post and adjusts the earring. This is the most secure type. If you want to wear the earrings for a long time, or are worried about losing your earrings, this is the one for you.

Shape

Diamond stud earrings come in a variety of different shapes, the most common being round, marquise and emerald. The one to go for depends on your personal taste, but a round diamond is a classic for a reason, and can be dressed up or dressed down accordingly.

Now it’s time to talk about the most important component of the earring: The lab grown diamond.

If we want to buy a lab grown diamond, we have to take into account the same criteria as if we were choosing a mined diamond. I am talking about the 4Cs– cut, color, carat and clarity.

Cut: The cut is how a diamond’s facets interact with light. If the proportions of the cut are correct, the diamond will have optimal brilliance and sparkle. In contrast, a poor cut allows light to escape through the bottom, and the diamond may appear dull or lack shine.

This criteria is often confused with the shape of the diamond, but they are completely different. Regardless of its shape, the diamond must have a good cut to ensure brilliance.

Color: Diamonds come in many different shades. Typically most people want a perfect clear and white diamond for their studs. Diamond color is graded from D (colorless) to Z (visible yellow/brown tint). Nobody wants a yellowish diamond, grade D/E are traditionally the most valuable.

It’s important not to be fooled; many times sellers try to pass off a Z-grade diamond as a fancy diamond (colored diamonds). Fancy diamonds are the most expensive, but the color must be intense, a beautiful yellow, not a dirty yellowish hue.

While lab grown colored diamonds are more expensive because the production cost is higher, it doesn’t compare to the high price of mined diamonds, due to their extreme rarity.

Be aware that the color of the metal that you choose for your diamond studs will impact the color of your diamond. If you have colorless diamonds (D, E, F grade) you should choose platinum or white gold. With near colorless diamonds (G,H, I) the best options are yellow gold, rose gold or sterling silver.

Carat Weight: Carat measures weight, not size. Therefore a diamond with a high carat size is not necessarily larger than one with a smaller carat size. This is why it is recommended, if possible, to buy a 0.98 carat diamond instead of a 1 carat diamond. This one is significantly more expensive and there is no difference in size.

Diamond earrings are sold based on their total carat weight; this is the total weight of all the diamonds in a pair of earrings. When you buy your studs, you’ll see it says 1 ct. tw. That means one carat per pair. Therefore, each individual stud will be 0.5 carats. Don´t forget about this detail.

I would choose a 1 carat total weight for my lab grown diamond studs; they’re just the right size to add a little bit of luxury to any look.

Clarity: The clarity of your diamond is not related to its color, but to the impurities it contains. Surface flaws are called blemishes, while internal characteristics are known as inclusions. The quality grade of a diamond depends on the location of these flaws. The more visible they are, the lower the clarity grade and the cloudier the diamond will appear.

In lab grown diamonds the flaws are often less noticeable and less frequent than those found in mined diamonds, due to the fact that they are created in controlled environments. If lab grown diamonds were flawless, it would be obvious at a glance that they aren’t mined. The presence of flaws makes it impossible to distinguish them with the naked eye, requiring us to take them to a laboratory for expert analysis.

Certification: When purchasing a lab grown diamond, it must have a certificate. There’s no discussion about that. It’s essential to choose a certified diamond, as grading reports provide assurance of a stone’s quality and authenticity.

Lab diamond certification is a document from a recognized laboratory (I only choose certification from GIA or IGI) that describes a diamond and its characteristics.

The certificate is used to compare diamonds and determine if the price is fair. Some people believe that diamonds with certificates are more expensive, but the truth is that diamonds without certificates usually end up being more expensive since there is no way to know if the price is fair or not, because their quality is unknown.
