Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, luminous silhouette across your hand. This semi-set halo engagement ring foundation in 14K yellow gold awaits your choice of a 6 x 3 mm marquise center, ready to frame the stone with a delicate circle of smaller gems that amplify its graceful drama.

Handcrafted in our Williamsburg studio, the band is shaped with a subtle comfort fit, its smooth interior contour designed for daily wear without intrusion. The low-profile halo setting balances presence with practicality, ensuring the ring slips easily beneath gloves or alongside stackable bands. Each curve and prong is meticulously finished and inspected to meet exacting standards of artisan craft.

Our commitment to ethical jewelry is reflected in the exclusive use of lab-grown diamonds, offering clarity and brilliance with a reduced environmental footprint.

This ring suits those who appreciate sculptural elegance and a refined silhouette that elongates the finger. Its semi-set state invites personal choice, making it an ideal canvas for a custom design journey.
