Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, graceful shadow that hints at quiet drama. This semi-set solitaire ring invites you to select a center stone measuring 12 by 6 millimeters, its pointed ends drawing the eye along the finger with elegant precision.

Crafted from 18K white gold, the mounting features a delicate yet sturdy setting designed in our Williamsburg studio. The artisan’s hand shapes each prong to cradle the stone securely while maintaining a low profile that slips comfortably beneath gloves or daily wear. The band’s smooth finish and balanced weight offer a refined feel without excess bulk.

Our commitment to sustainability is reflected in the choice of lab-grown diamonds, combining clarity and brilliance with an ethical footprint that respects both people and planet.

This design suits those who appreciate architectural lines and a statement piece that remains wearable every day. The marquise shape elongates the finger, while the solitaire style keeps the focus pure and uncluttered. Its semi-set nature allows for personalized selection of a diamond that matches your vision.

Should resizing be needed, our Brooklyn studio provides expert adjustments to ensure a perfect fit without compromising the ring’s integrity.
