Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of the marquise diamond, casting a slender, luminous silhouette that seems to stretch beyond the finger. This semi-set halo ring foundation in 10K white gold invites your choice of an 8 x 4 mm marquise center, framed by a delicate halo that amplifies its sculptural elegance.

Each band is meticulously crafted in our Williamsburg studio, where the cool sheen of white gold is hand-finished to a smooth, comfort fit that sits low against the skin for everyday grace. The halo setting is designed to enhance brilliance while maintaining a refined profile, ideal for stacking or wearing solo without catching on gloves or sleeves.

Our commitment to sustainability is reflected in the lab-grown diamond clarity this ring embraces—ethical jewelry that honors both beauty and responsibility.

This ring suits those who appreciate architectural lines and a subtle statement, especially flattering on slender fingers or paired with complementary bands for a personalized stack. The semi-set design allows you to select a marquise stone that resonates with your vision, ensuring a truly bespoke experience.

Resizing is straightforward and handled with care in-studio, ensuring your ring fits comfortably for a lifetime of wear.
