Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated marquise diamond, casting a slender beam that dances across the hand. This three-stone engagement ring balances architectural precision with modern minimalism, its 8 x 4 mm marquise center framed by two delicate side stones that enhance its confident silhouette.

Crafted in warm 14K yellow gold, the band is polished to a soft glow and shaped for comfort, offering a low-profile setting that slips easily beneath gloves or alongside other rings. Each stone is securely set with clean prongs, allowing light to travel freely through the facets, revealing the diamond’s signature tapered drama.

Our commitment to sustainability shines through the lab-grown clarity of the marquise diamond, ethically sourced and expertly cut to maximize brilliance without compromise.

This ring suits those who appreciate structured elegance with a contemporary edge—its slender shape elongates the finger while the three-stone design adds meaningful depth. The comfort fit band supports daily wear, whether worn solo or stacked with complementary bands.

Resizing is available to ensure a precise fit, crafted carefully in our Williamsburg studio to maintain the ring’s refined proportions.
