Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a delicate rose gold band. This semi-set halo engagement ring invites your choice of a 10 x 5 mm marquise center, framed by a handcrafted halo that amplifies its vintage-inspired drama.

Forged in warm 14K rose gold, the band is shaped with subtle contours for a comfortable fit that rests lightly against the skin. Each halo setting is meticulously finished in our Williamsburg studio, ensuring the prongs cradle your stone securely while maintaining a low profile that slips easily beneath gloves or daily wear.

Our commitment to sustainability shines through the lab-grown diamond option, offering clarity and brilliance with a reduced environmental footprint. This ring’s slender silhouette suits hands that appreciate refined elegance and works beautifully as a standalone statement or paired with complementary bands.

Should you need adjustments, resizing is handled with care to preserve the ring’s delicate proportions. Typical lead times reflect our artisan process, allowing space for thoughtful customization.
