If you’re looking for a timeless ring, a round cut diamond is for you. Round cut diamonds are the most popular to date, cornering nearly 75% of the diamond market. But just because it's the most popular doesn't mean that it's not unique. You can add a pop of color or a customized halo this diamond to make it unique to you.

These diamonds are stable in shape and are generally considered to be one of the least likely diamond cuts to fall out of a setting, making it able to be featured in lots of different settings. And because the diamond is fully curved, it gives off the most light of any diamond cut out there. Whether you're looking for a classic solitaire or a pavé halo style, a round-cut diamond ring will be stunning no matter the design.

Round Diamond Ring FAQ

1. What Is A Round Diamond Ring?


A round diamond ring is a ring in which the main stone is in the shape of a circle, or a grouping of smaller stones makes a circular shape.

2. What Is The GIA?


The GIA is an independent, nonprofit organization that conducts gem research, educates gem professionals and sets the standards for determining diamond quality. One of GIA’s main functions is the grading of diamonds. The GIA created the 4Cs of diamond quality: color, clarity, cut and carat weight, along with the scientific procedures for evaluating each “C” and the grading terminology used to describe them.

The GIA does not mine diamonds, nor does it buy, sell, or trade them commercially. It doesn’t appraise diamonds and is not otherwise involved in diamond pricing or valuation. GIA operates independently of these commercial interests, ensuring that its diamond quality assessments are objective and unbiased.

3. What Is A GIA Certified Diamond?


The GIA doesn’t actually certify diamonds; it grades them. The terms “GIA certified” and “GIA cert” are commonly used in the jewelry industry to refer to diamonds that have undergone GIA’s rigorous grading process and to the reports that accompany the diamonds. The GIA itself does not use the word “certificate” to describe the document it issues. The GIA examines the diamond, assesses its qualities based on the 4Cs, and describes it. It does not certify the diamond or its value.

4. Where Can You Buy Them?


These rings can be purchased at any jeweler, and they can also be purchased online.

5. Price Range


These rings can range in price from $200 to upwards of $5000.
