Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curve of a marquise diamond, casting a slender, luminous silhouette that seems to stretch beyond the finger. This semi-set engagement ring invites you to choose your own 5 x 3 mm marquise center, a shape known for its graceful taper and subtle drama.

Crafted in warm 10K yellow gold, the band is polished to a gentle sheen that complements the diamond’s fiery facets. The solitaire setting is designed with a delicate yet secure prong structure, allowing light to flood the stone’s edges while maintaining a low profile for everyday comfort. Each ring is finished by hand in our Williamsburg studio, where precision meets quiet artistry.

Our diamonds are lab-grown, offering clarity and brilliance with a mindful footprint—an ethical choice that honors both beauty and sustainability.

The slender band suits those who appreciate refined elegance and a ring that layers effortlessly with wedding bands or stackable pieces. Its modest height ensures it slips easily beneath gloves or sleeves, making it a natural companion for daily wear.

Should you need resizing, our Brooklyn studio offers personalized adjustments to ensure your ring fits just right without compromising its delicate balance.
