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 with elegant drama. This semi-set halo ring foundation in 18K yellow gold frames a 12 x 6 mm marquise center with a handcrafted band that balances boldness and subtlety.

Each curve of the yellow gold shank is meticulously shaped in our Williamsburg studio, finished to a soft, warm glow that feels smooth against the skin. The halo setting is designed to amplify the marquise’s signature brilliance while maintaining a low profile that slips comfortably beneath gloves or daily wear.

Crafted with lab-grown diamonds, this piece carries a clarity and sparkle that honors sustainable practices without compromise. The ethical origin of the center stone reflects a commitment to responsible luxury.

Ideal for those who appreciate architectural grace paired with artisanal detail, this ring suits hands that welcome a statement piece with refined presence. Its semi-set nature invites you to select a marquise diamond that resonates personally, ensuring a truly custom expression.

Resizing is available to accommodate your unique fit, with careful attention to preserving the ring’s balance and comfort.
