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 rose gold. This semi-set halo ring invites your choice of a 9 x 4.5 mm lab-grown marquise, framed by a fine halo that amplifies its sculptural elegance without overwhelming the hand.

Crafted from warm 18K rose gold, the band is shaped and polished in our Williamsburg studio to a smooth comfort fit, designed for everyday wear. The halo setting is meticulously hand-set, each tiny accent diamond secured with precision to enhance brilliance while maintaining a low profile that slips easily beneath gloves or sleeves.

Our diamonds are lab-grown with clarity and sustainability in mind, reflecting a commitment to ethical jewelry that honors both beauty and responsibility.

This ring suits those who appreciate architectural grace paired with subtle warmth—its narrow shape elongates the finger, while the halo adds a whisper of vintage allure. The semi-set design allows you to select a center stone that resonates personally, making this piece uniquely yours.
