Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its pointed ends tracing a delicate arc that seems to stretch the fingers gracefully. This semi-set halo engagement ring in warm 14K yellow gold frames a 9 x 4.5 mm marquise stone, designed to amplify its signature tapered drama with a ring of smaller diamonds that catch light from every angle.

Handcrafted in our Williamsburg studio, the band is shaped for comfort with a subtle curve that rests naturally against the skin. The low-profile halo setting balances presence with wearability, ensuring the ring slips easily beneath gloves or stacks seamlessly with a wedding band. Each element is meticulously finished by hand, polished to a soft glow that complements the rich warmth of yellow gold.

Our commitment to ethical jewelry is reflected in the choice of a lab-grown marquise diamond, offering clarity and brilliance with a smaller environmental footprint. This ring suits those who appreciate architectural elegance paired with artisanal detail, especially flattering on slender fingers where the elongated shape enhances natural grace.

Should you wish to customize the center stone or inquire about resizing, our Brooklyn studio offers a personalized, pressure-free experience with transparent timelines and care guidance.
