01

The Right Balance

At 3 carats, a diamond sits beautifully on nearly every hand size. It reads as genuinely large and impressive, while remaining practical for everyday wear.

02

Lab or Natural

We offer both GIA-certified natural and lab-grown diamonds at 3 carats. Lab diamonds deliver the same optical properties at a significantly lower price, allowing you to invest more in the setting or a higher grade stone.

03

Made to Order

Every 3 carat ring we create starts with your stone selection. The ring is then designed around its exact measurements, so nothing is generic and nothing is off-the-shelf.

Frequently Asked Questions About 3 Carat Engagement Rings

What factors influence the price of a 3-carat diamond engagement ring? −

The price of a 3-carat diamond engagement ring is influenced by various factors, including the diamond's cut, color, clarity, and carat weight. Additional considerations include the choice of metal for the setting, the reputation of the jeweler, and whether the diamond is natural or lab-grown. Our team can walk you through all of these variables to help you find the best value within your budget.

Are there popular engagement ring settings that complement a 3-carat diamond? +

Yes, several engagement ring settings enhance the beauty of a 3-carat diamond. Popular choices include the classic solitaire setting, which lets the stone speak for itself, the halo setting, which adds a ring of pavé diamonds around the center stone, and the three-stone setting, which flanks the diamond with two complementary side stones. Each style offers a distinct look, and our jewelers can help you find the right match for your partner's taste.

What is the significance of the 4 Cs when selecting a 3-carat diamond? +

The 4 Cs - cut, color, clarity, and carat weight - are the universal standard for evaluating a diamond's quality. Cut determines how brilliantly the diamond reflects light, color refers to the absence of yellow or brown tones in white diamonds, clarity measures the presence of internal inclusions or surface blemishes, and carat weight indicates the size of the stone. At 3 carats, cut quality becomes especially important, as it has the greatest impact on how the diamond looks in person.
