Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, dramatic silhouette across the hand. This semi-set engagement ring invites you to select a 10 x 5 mm marquise stone that balances architectural grace with a subtle vintage allure.

Crafted in warm 14K yellow gold, the mounting features a low-profile solitaire setting designed for everyday wear. Its secure prongs cradle the stone close to the finger, minimizing snagging while maintaining a refined presence. The band’s smooth finish and gentle taper ensure comfort throughout daily life, whether worn solo or stacked.

Each ring is meticulously hand-finished in our Williamsburg studio, where precision meets quiet durability. The semi-set design allows for personalized stone selection, offering flexibility without compromising the integrity of the setting.

Our commitment to sustainability is reflected in the exclusive use of lab-grown diamonds, chosen for their clarity and ethical provenance.

This ring suits those who appreciate a sleek, elongated profile that complements slender fingers or adds length to shorter ones. Its low profile and comfort fit make it an ideal choice for active lifestyles and glove-friendly wear.

Should you need resizing, our in-studio experts ensure a seamless adjustment without disrupting the ring’s balance or finish.
