Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its pointed ends tracing a delicate arc that seems to stretch the hand with quiet elegance. This semi-set solitaire ring invites you to select a center stone that balances vintage allure with modern refinement.

Crafted from warm 18K yellow gold, the mounting features a slender band designed for comfort and everyday wear. The low-profile setting ensures the diamond sits close to the finger, making it glove-friendly and ideal for stacking alongside wedding bands or delicate accents. Each ring is meticulously finished by hand in our Williamsburg studio, where precision meets subtle artistry.

Our commitment to sustainability shines through the choice of lab-grown diamonds, offering clarity and brilliance with a reduced environmental footprint. This ethical foundation complements the ring’s thoughtful design, made to accompany daily moments with understated grace.

Sized to fit a variety of hands, the marquise shape’s elongated form flatters slender fingers and adds a touch of architectural drama without overwhelming. The semi-set style allows you to personalize the centerpiece, ensuring your engagement ring is as unique as your story.

Should you need resizing or guidance on selecting the perfect stone, our Brooklyn studio offers a pressure-free consultation to help you navigate every detail with care.
