Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of a hand caught in soft Brooklyn light, where a marquise diamond’s tapered points draw the eye with quiet drama. This semi-set solitaire invites you to select a 10 x 5 mm lab-grown marquise, its distinctive shape balancing vintage allure with modern geometry.

Crafted in 18K white gold, the mounting features a low-profile setting designed for everyday wear. The slender prongs hold the stone securely while allowing maximum light to pass through, enhancing the diamond’s signature brilliance. The band’s smooth finish and comfort fit ensure it rests naturally, whether worn solo or stacked alongside other favorites.

Each piece is meticulously finished in our Williamsburg studio, where expert hands inspect every angle to meet exacting standards. The ethical clarity of the lab-grown diamond reflects a commitment to sustainability without compromise.

This ring suits those who appreciate refined engineering and understated elegance, especially for hands that favor a sleek silhouette. Its low profile makes it glove-friendly and ideal for daily life, while the marquise shape adds a distinctive edge to classic solitaire style.
