Lab-Grown Diamond Engagement Ring

Sunlight catches the sharp edges of a 9 x 9 mm square diamond, its facets unfolding like a quiet architectural poem across the hand. This five-stone semi-set engagement ring in 18K yellow gold frames the center stone with four delicate companions, each precisely set to enhance the geometric clarity and subtle fire of the square cut.

Crafted in Williamsburg, the band’s warm gold hue is hand-polished to a soft glow, balancing presence with everyday wearability. The setting sits low enough to slip comfortably beneath gloves or stack alongside wedding bands without catching, while the semi-set design invites your choice of a lab-grown center diamond, ensuring a personalized expression of commitment.

Each lab-grown diamond reflects a commitment to sustainability, offering clarity and brilliance without the environmental cost of traditional mining. The ring’s proportions suit hands that appreciate modern geometry with a romantic edge, its clean lines elongating the finger and harmonizing with a variety of styles.

Resizing is available to ensure a perfect fit, and the semi-set nature allows for thoughtful selection of the center stone, with typical lead times communicated during your consultation. Whether visiting our Williamsburg studio or designing online, this ring invites a collaborative experience grounded in craft and care.
