Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a delicate shadow that dances with every movement. This semi-set solitaire invites you to choose a center stone that embodies your story, its 6 x 3 mm proportions offering a graceful, tapered drama that elongates the finger with subtle elegance.

Crafted from warm 18K rose gold, the slender band curves softly beneath the stone, designed for everyday wear with a low-profile setting that nestles close to the hand. Each piece is meticulously finished in our Williamsburg studio, where expert hands polish and inspect every contour to ensure a seamless balance of comfort and refined craftsmanship.

Our commitment to ethical jewelry shines through the use of lab-grown diamonds, offering clarity and brilliance with a lighter environmental footprint.

The slender silhouette suits those who appreciate romantic minimalism and a ring that layers effortlessly with other bands or stands alone with quiet confidence. Its comfort fit and modest height make it glove-friendly and ideal for daily life in Brooklyn’s vibrant rhythm.

Should you wish to adjust the band size, resizing is handled with care to maintain the integrity of the rose gold finish and setting.
