Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of the marquise, casting a delicate shadow that dances with every movement. This semi-set halo engagement ring in 14K white gold frames an 8 x 4 mm marquise center stone, inviting you to choose a lab-grown diamond that balances architectural grace with a whisper of vintage allure.

Crafted in Williamsburg, the band’s polished white gold offers a cool, smooth touch against the skin, while the halo setting enhances the stone’s brilliance without adding bulk—ideal for those who favor a low-profile elegance. Each piece is meticulously finished by hand, ensuring comfort fit and durability for daily wear.

Our commitment to ethical jewelry shines through the use of lab-grown diamonds, which provide clarity and sparkle with a significantly reduced environmental footprint.

The slender shape of the marquise naturally elongates the finger, making this ring a refined choice for those who appreciate subtle drama and timeless geometry. Its halo setting also pairs beautifully with stackable bands or a delicate wedding band.
