How to Pick An Engagement Ring Diamond

Embarking on the journey toward marital bliss begins with one of the most significant decisions you'll make: selecting the perfect engagement ring diamond. This sparkling token of love isn't just a piece of jewelry; it's a symbol of your commitment, love, and the unique story you share with your partner.

Understanding the importance of this choice is paramount. Let's dive into the intricacies of picking the right diamond by exploring the 4 Cs, the influence of shape and setting, and some expert tips to guide your decision.

Understanding the 4 Cs of Diamonds

Navigating the world of diamonds starts with a solid understanding of the 4 Cs: Carat, Cut, Color, and Clarity. These qualities immensely influence a diamond's beauty and value.



Carat refers to the weight of the diamond. While larger diamonds are often more coveted due to their rarity, remember that carat weight doesn't alone dictate the gem's brilliance or value. It's about finding the perfect balance between size and quality within your budget.



The cut of a diamond impacts its sparkle more than any other factor. A well-cut diamond will have unmatched brilliance, as it allows for the maximum amount of light to both enter and reflect off the diamond surfaces. Consider cuts that suit your partner's style and enhance the stone's natural luster.

Common diamond cuts include round, princess, emerald, and cushion. Each shape has its unique qualities that play into personal preference and style.



Diamonds come in a range of colors, graded from D (colorless) to Z (light color). The diamond color grading scale is based on the absence of color, with D being the most valuable.

D-F Colorless

D-F: Colorless

G-J Near Colorless

G-J: Near colorless

K-M Faint Yellow

K-M: Faint yellow



Clarity refers to the diamond's internal characteristics, also known as inclusions. These are tiny imperfections that occur naturally during the diamond's formation process and can affect its overall appearance. The clarity grade ranges from flawless (FL) to included (I).

All of the clarity grade range  may have visible inclusions, but the size, location, and type of imperfections determine its category. Keep in mind that most diamonds have some level of inclusions, and they may not necessarily impact their beauty.

Shape and Setting: Crafting the Perfect Look

Your choice of diamond shape and setting can radically affect the ring's overall appearance. From classic rounds to elegant fashion rings, the shape of the diamond should resonate with your partner's taste. The setting, whether it be a secure solitaire for a minimalist appeal or a lavish halo for added sparkle, should complement the diamond, amplifying its beauty.

But how do you pick?

How to Pick Shape and Setting For An Engagement Ring Diamond

When selecting the shape and setting of an engagement ring diamond, consider your partner's personal style and daily activities.


Each shape, also known as a cut, holds its own symbolic meaning and aesthetic appeal.

Round Cut Diamond

For example, the timeless round cut represents endless love and is renowned for its incredible brilliance. 

Emerald Cut Diamond

The sleek lines of an emerald cut diamond, on the other hand, exude elegance and sophistication.


The setting, on the other hand, not only secures the diamond in place, but also contributes to the ring's final design and comfort.

Prong Setting

A prong setting allows for maximum light exposure, enhancing the stone's fire and sparkle.

Bezel Setting

A bezel setting, alternatively, offers a sleek and modern look with added protection—ideal for those with an active lifestyle.

Mixed metals, filigree, and even pavé diamonds can add a touch of personality and highlight the diamond's features.

Consider consulting with a jeweler like Fuller's to view different combinations in person, allowing you to observe how light interacts with the diamond's shape and how the setting complements your chosen cut. Remember, this ring is an extension of your partner's persona, so choose a combination that they'll love to wear every day.
