Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of the marquise diamond, casting a slender, dramatic silhouette across the hand. This three-stone semi-set engagement ring features an 8 x 4 mm marquise center, poised between two delicately tapered side stones, all cradled in warm 10K yellow gold.

Crafted with a low-profile setting, the band sits close to the finger for everyday comfort without sacrificing brilliance. The smooth finish and subtle tapering ensure it layers effortlessly with other bands or stands alone with quiet confidence. Each prong is meticulously shaped and polished in our Williamsburg studio, ensuring secure wear and refined detail.

Our diamonds are lab-grown, offering clarity and sparkle with a smaller environmental footprint, reflecting a modern approach to ethical jewelry.

Designed for those who appreciate architectural elegance and practical wearability, this ring complements slender to medium finger shapes, its narrow marquise form elongating the hand gracefully. The semi-set design invites you to select a center stone that matches your vision, making it a truly personal statement.

Resizing is straightforward and handled in-house, preserving the integrity of the setting and metalwork.
