Lab-Grown Diamond Engagement Ring

When sunlight catches the elongated silhouette of a marquise diamond, it casts a subtle, graceful shadow that seems to stretch beyond the hand. This semi-set engagement ring foundation, crafted in 14K white gold, awaits a 9 x 4.5 mm marquise stone to complete its refined profile.

The band’s smooth, polished surface is shaped for comfort, with a low-profile setting designed to sit close to the finger, making it ideal for daily wear. Each curve and angle is carefully finished by hand in our Williamsburg studio, ensuring a seamless balance between strength and elegance.

Our commitment to sustainability is reflected in the choice of a lab-grown diamond, offering clarity and brilliance with a significantly reduced environmental footprint.

This mounting suits those who appreciate a sculptural, vintage-inspired silhouette that elongates the finger, pairing beautifully with slender or medium-width bands for stacking. Its modest height and secure prongs make it glove-friendly and practical for an active lifestyle.

Should you need resizing, our in-house artisans adjust the band with precision to maintain its original comfort fit and structural integrity.
