Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a delicate arc of light. This three-stone engagement ring, set in warm 14K yellow gold, balances architectural drama with handcrafted subtlety.

Each diamond is securely nestled in a low-profile setting, allowing the stones to sit close to the finger for everyday comfort. The band’s smooth finish and gentle curve reflect meticulous artisan work, polished by hand in our Williamsburg studio to a soft glow that complements the vibrant gold.

Our marquise diamonds are lab-grown, offering a clarity and brilliance that honors both ethical sourcing and environmental mindfulness without compromise.

Designed for those who appreciate a statement piece that remains wearable, this ring’s slender band and tapered shape suit slender to medium finger sizes, pairing effortlessly with wedding bands or stackable rings. Its low profile ensures it slips easily under gloves or sleeves, making it a practical choice for daily life.

Should you need a custom fit, resizing is available through our Brooklyn workshop, ensuring your ring feels as natural as it looks.
