Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated marquise center, casting a slender beam of brilliance that dances across the hand. This three-stone engagement ring, set in warm 14K yellow gold, balances architectural elegance with everyday ease.

Each diamond is securely nestled in a low-profile setting that minimizes snagging while maximizing light return. The smooth comfort-fit band curves gently, designed to wear seamlessly from morning coffee to evening plans. Expertly finished in our Williamsburg studio, the ring undergoes meticulous inspection to ensure flawless craftsmanship.

Crafted with a lab-grown marquise diamond, this ring reflects a commitment to ethical jewelry—offering clarity and sparkle without compromise. The 8 x 4 mm center stone’s tapered points create a striking silhouette that elongates the finger, ideal for those who appreciate refined geometry and subtle drama.

Its slender profile and balanced weight make it an excellent choice for stacking alongside wedding bands or daily rings. The secure three-stone setting also accommodates resizing with ease, ensuring a lasting fit.
