Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a delicate arc of light. This semi-set halo engagement ring foundation in 18K white gold awaits your choice of a 6 x 3 mm marquise center, designed to amplify the stone’s dramatic, vintage-inspired profile.

Crafted in our Williamsburg studio, the band features a finely detailed halo setting that cradles the center stone with artisan precision. The low-profile mount ensures daily comfort and ease under gloves or alongside stackable bands, while the polished 18K white gold offers a cool, luminous backdrop that enhances the diamond’s brilliance without distraction.

Each piece reflects our commitment to ethical jewelry: the setting is made exclusively for lab-grown diamonds, reducing environmental impact without compromising clarity or fire.

This ring suits those who appreciate architectural elegance with a touch of classic romance, especially flattering on slender fingers where the marquise shape elongates the hand. Its subtle height and secure halo make it ideal for active wearers seeking both style and practicality.

Should you wish to adjust the fit, resizing is available to ensure your ring feels as natural as it looks.
