Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of the marquise diamond, its tapered points drawing the eye along the finger with quiet drama. This semi-set solitaire ring awaits your choice of an 8 x 4 mm lab-grown marquise, a shape known for its graceful elongation and subtle vintage allure.

Crafted in warm 18K rose gold, the mounting features a low-profile setting designed for everyday wear. The band’s smooth contour ensures comfort fit, while the secure prongs cradle the stone without excess height, making it glove-friendly and stackable with ease. Each piece is meticulously finished and inspected in our Williamsburg studio, reflecting a commitment to precision and durability.

Choosing a lab-grown diamond aligns with a thoughtful approach to ethical jewelry, minimizing environmental impact without compromising brilliance or clarity.

This ring suits those who appreciate refined geometry and a silhouette that visually lengthens the finger, ideal for slender or medium-width hands. Its understated profile complements both casual and formal styles, adapting seamlessly to daily life.
