Shop by Stone Type

At 3 carats, the character of the diamond becomes unmistakable. From bright, high-clarity stones to those with a softer, more natural feel, each choice shapes the overall look. It’s about selecting a diamond that feels composed, balanced, and right to you.

SHOP BY

Shop by Shape

Shape plays a defining role at this size. Elongated cuts like oval and emerald create a more refined silhouette, while round offers a classic presence. Cushion and pear bring a softer edge, adding individuality without losing elegance.

SHOP BY

Shop by Popular Carat Sizes

A 3 carat diamond sits firmly in statement territory, with a presence that’s hard to miss. Some choose slightly smaller sizes for a lighter feel, while others go larger for added impact. The difference lies in how it wears, not just how it looks.

Engagement Ring Trends

Engagement Ring Trends

3 carat engagement rings have quietly become a study in restraint. Clean solitaires let the diamond speak for itself, while elongated shapes bring an easy elegance that feels current without trying to be. Where detail appears — a fine pavé band, a hidden accent — it's used with a light touch. Enough to add character, not enough to compete with the stone. Our artisans work with each diamond individually, shaping a design around it rather than to it. The result is something that feels considered, personal, and made to be worn for a lifetime.
