Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, graceful shadow across the hand. This semi-set solitaire invites you to select a 6 x 3.5 mm center stone that balances dramatic presence with refined subtlety.

Crafted in 14K yellow gold, the mounting features a low-profile design that sits close to the finger, minimizing snagging and enhancing comfort for everyday wear. The slender prongs secure the stone while maintaining an open view to its distinctive tapered shape, allowing light to travel freely through the facets.

Each ring is finished by hand in our Williamsburg studio, where precise polishing and inspection ensure a smooth band and a secure setting. The warm gold tone complements the marquise’s vintage-inspired silhouette without overwhelming it.

Our commitment to ethical jewelry is reflected in the option for a lab-grown diamond center, offering clarity and brilliance with a smaller environmental footprint.

This solitaire suits those who appreciate architectural elegance and a ring that integrates seamlessly with daily life—whether worn alone or stacked with complementary bands. Its low profile and comfort fit make it glove-friendly and ideal for active hands.
