Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, graceful shadow across the hand. This semi-set solitaire ring in 14K yellow gold awaits your choice of a 10 x 5 mm marquise center, offering a refined silhouette that balances presence with subtlety.

Crafted with a low-profile setting, the band curves gently for comfort and ease of wear, designed to sit close to the finger without catching. The polished 14K yellow gold shank is shaped for daily life—durable yet elegant, with smooth edges that invite touch. Each mounting is meticulously finished and inspected in our Williamsburg studio to ensure precision and longevity.

Our commitment to ethical jewelry is reflected in the exclusive use of lab-grown diamonds, combining clarity and sustainability without compromise.

The slender marquise shape naturally elongates the finger, ideal for those who appreciate a ring that feels both distinctive and wearable. Its solitaire design pairs effortlessly with other bands or stands alone, making it versatile for stacking or solo wear. The semi-set option allows you to select a stone that speaks personally, ensuring a truly custom expression.
