Lab-Grown Diamond Engagement Ring

When sunlight catches the elongated silhouette of a marquise diamond, it casts a slender, dramatic sparkle that seems to stretch beyond the finger. This semi-set solitaire mounting, crafted from warm 18K rose gold, offers a subtle contrast against the cool gleam of white gold accents, framing a 10 x 5 mm marquise center with quiet precision.

Each band is shaped and polished in our Williamsburg studio, where artisan hands ensure a low-profile setting that sits close to the skin for everyday comfort. The delicate prongs cradle the stone securely while allowing light to flood the facets, enhancing the marquise’s signature brilliance and tapered drama.

Our diamonds are lab-grown, reflecting a commitment to sustainability and ethical sourcing without compromising on clarity or fire. This ring’s slender silhouette and modest height make it ideal for those who appreciate refined elegance and a design that layers effortlessly with wedding bands or stackable rings.

Designed for hands that favor grace and subtlety, the comfort-fit band adapts well to daily wear and pairs beautifully with gloves or other jewelry. Should you need resizing, our Brooklyn studio offers personalized adjustments to ensure a perfect fit.
