Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the finger with a quiet drama. This semi-set halo ring in 14K white gold offers a delicate frame for a 10 x 5 mm center stone, designed to amplify the diamond’s signature brilliance while maintaining a refined profile.

Handcrafted in our Williamsburg studio, the band is shaped for comfort with a subtle curve that rests naturally against the skin. The halo setting, meticulously finished by hand, enhances the marquise’s architectural elegance without adding bulk—ideal for daily wear and effortless stacking. Each piece undergoes rigorous inspection to ensure the metal’s smooth polish and the setting’s secure hold.

Our commitment to ethical jewelry is reflected in the use of a lab-grown diamond, offering clarity and sparkle with a reduced environmental footprint. This ring suits those who appreciate sculptural form and understated sophistication, especially flattering on slender fingers where the marquise shape elongates the hand.

Should you need a custom fit, resizing is available to ensure the ring feels as natural as it looks. Lead times are transparent and tailored to your design choices.
