The cost of diamond earrings depends on several factors. To begin with, you'll have to consider the diamond shape (round brilliant diamonds generally cost more than fancy shapes). Next, you should know that the larger the diamonds in the earrings (carat size), the more expensive they will be.
You'll then want to consider the color, clarity, and the type of metal they are set in. If you want diamond earrings with the least amount of color possible, they need to have a better color grade which means you will pay more. If color grade doesn't matter as much to you, then you can go with a lower grade, save a bit of money, and still get a beautiful set of studs.
Clarity matters most if you're going to buy a pair of diamond stud earrings with a shape that doesn't hide inclusions well. For instance, a step-cut diamond like an emerald and Asscher cut allows you to see inside of it. This means inclusions on these types of diamonds are more obvious to the naked eye. However, when it comes to round, oval, cushion, and even shapes like a pear or princess cut, small inclusions are not so obvious.
If want a pair of earrings with a step-cut diamond, then consider a better clarity rating. If you want a classic round, you can save yourself some money and choose a pair of earrings with a lower clarity rating.
The metal your earrings are set in will also affect the price. Platinum is going to be expensive, whereas white gold, yellow gold, and rose gold will be more affordable.
And beyond the price differences between each metal, the color of the metal you choose can also make your diamond look whiter and brighter. This is especially helpful if you choose a diamond with a lower color grade. A white metal like platinum or white gold will make your diamonds appear whiter without the added cost of a D-F color grade.
Lab Grown Diamonds Are Competitively Priced
One final point to keep in mind about how much diamond earrings are (no matter if they're diamond hoops, studs, or drop earrings) is that lab grown diamonds are 20-40% less expensive than natural diamonds. So when you buy lab grown you can be sure you're getting the best price on truly ethical jewelry.
