Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of the marquise diamond, its tapered points drawing the eye along the hand with subtle drama. This 10 x 5 mm center stone is securely nestled in a 14K rose gold setting, where delicate accent stones trace the band’s gentle curve without adding bulk.

Crafted for everyday grace, the low-profile mounting keeps the ring close to the finger, minimizing snagging while maintaining a refined presence. The smooth finish and comfort fit band ensure it wears effortlessly from morning light to evening shadows, a quiet companion to daily life.

Each diamond is lab-grown, offering a clarity and brilliance that honors both beauty and sustainability. This ethical choice reflects a commitment to responsible craftsmanship without compromise.

Ideal for those who appreciate a distinctive shape with a modern touch, the marquise’s elongated form visually lengthens the finger, pairing well with slender or average-sized hands. Its streamlined silhouette also makes it an excellent candidate for stacking alongside wedding bands or other fine jewelry.

Should you need a custom adjustment, resizing is handled with care in our Williamsburg studio to maintain the ring’s integrity and comfort.
