Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, dramatic shadow across the hand. This semi-set three-stone ring invites you to choose a center stone that measures 12 by 6 millimeters, its tapered points lending a graceful, vintage-inspired flair.

Crafted from 18K white gold, the mounting features a delicate balance of strength and refinement, with hand-finished prongs designed to cradle your chosen diamond securely while maintaining a low-profile silhouette. The side stones frame the center with subtle brilliance, enhancing the ring’s architectural elegance without overwhelming daily wear.

Each piece is meticulously shaped and polished in our Williamsburg studio, where artisan hands ensure a smooth comfort fit that feels natural against the skin. The semi-set design offers flexibility, allowing you to select a lab-grown diamond that aligns with your vision and ethical values.

Lab-grown diamonds provide a clear, sustainable alternative to mined stones, reflecting a commitment to responsible craftsmanship without compromising on radiance or quality.

This ring suits those who appreciate refined geometry and a statement that elongates the finger, pairing well with stackable bands or worn solo for understated drama. Its low profile and secure setting make it glove-friendly and ideal for everyday life.
