Lab-Grown Diamond Engagement Ring

When sunlight catches the elongated silhouette of this marquise diamond, it casts a delicate, tapered sparkle that dances across the hand. The 12 x 6 mm center stone is cradled within a halo of meticulously set pavé diamonds, amplifying its signature brilliance with a whisper of vintage allure.

Crafted from cool 14K white gold, the band is polished to a satin finish that feels smooth against the skin, designed with a low-profile setting to sit comfortably beneath gloves or daily wear. Each diamond is hand-selected and set in our Williamsburg studio, where precision meets artisan care in every prong and pavé bead.

Our commitment to sustainability shines through the lab-grown clarity of the marquise diamond, offering an ethical alternative without compromise on fire or scintillation.

This ring suits those who appreciate a statement piece that elongates the finger, balancing bold geometry with refined comfort. Its halo setting adds dimension while maintaining a sleek silhouette, ideal for stacking with wedding bands or wearing solo.

Should you need resizing, our Brooklyn workshop handles adjustments with care to preserve the integrity of the setting and stone alignment.
