Lab-Grown Diamond Engagement Ring

The elongated silhouette of the marquise center stone catches light with a subtle, tapered drama that draws the eye along the finger’s natural line. This semi-set three-stone ring invites your choice of a 6 x 3.5 mm lab-grown diamond, framed by two delicately crafted side stones that balance brilliance with architectural grace.

Hand-forged in 14K yellow gold, the band’s smooth finish and gently rounded edges ensure a comfort fit that wears effortlessly every day. The setting’s low profile keeps the stones secure while maintaining an elegant presence without catching on fabric or gloves. Each piece is meticulously inspected in our Williamsburg studio, where artisan techniques meet modern precision.

Our commitment to ethical jewelry is reflected in the clarity and sustainability of the lab-grown diamonds, offering a conscious alternative without compromise on sparkle or character.

This ring suits those who appreciate a refined statement with a vintage-inspired silhouette, ideal for slender fingers or anyone seeking a piece that layers beautifully with wedding bands or stackable rings. Its balanced proportions make it a versatile choice for daily wear and special moments alike.

Should you need resizing or prefer a custom stone selection, our Brooklyn studio offers personalized consultations to ensure your ring fits perfectly and reflects your vision.
