Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, luminous silhouette across the hand. This three-stone semi-set ring invites you to select a center stone that balances drama with refined elegance.

Crafted from warm 14K yellow gold, the band is shaped and polished in our Williamsburg studio to a smooth comfort fit that wears effortlessly every day. The side stones frame the center with delicate prongs, designed low enough to slip easily beneath gloves or stack alongside other bands without catching.

Each lab-grown diamond offers a clarity and brilliance that honors sustainable practices, reflecting a commitment to ethical jewelry without compromise.

The marquise shape, with its tapered ends and elongated form, visually lengthens the finger, making it a striking choice for those who appreciate architectural grace paired with subtle vintage allure.
