Lab-Grown Diamond Engagement Ring

Imagine the subtle drama of a marquise diamond, its elongated silhouette catching light with a quiet, confident gleam. This semi-set halo engagement ring foundation in 10K yellow gold frames a 7 x 3.5 mm center stone, designed to amplify the marquise’s signature pointed elegance with a delicate circle of accent diamonds.

Crafted in Williamsburg, the band’s smooth finish and modest profile ensure comfort for daily wear, while the halo setting adds a structured brilliance that balances modern minimalism with architectural clarity. The yellow gold’s warm tone complements the marquise shape’s vintage-inspired allure without overwhelming its refined geometry.

Each piece is thoughtfully made with lab-grown diamonds, reflecting a commitment to ethical sourcing and sustainability without compromise on sparkle or clarity.

Its low-profile design suits hands that appreciate subtle statement pieces, ideal for stacking or wearing solo. The semi-set nature invites you to select a marquise center stone that matches your personal vision, making this ring a truly bespoke starting point.

Resizing is straightforward, and our Brooklyn studio offers personalized guidance to ensure your ring fits perfectly and reflects your style.
