Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its pointed ends tracing a delicate arc across the finger. This three-stone engagement ring in platinum frames a 10 x 5 mm marquise center with two gently tapered side stones, creating a subtle narrative of balance and grace.

Crafted in Williamsburg, each platinum band is hand-finished to a satiny smoothness that feels weightless yet substantial. The low-profile setting secures the stones closely to the finger, allowing for everyday wear without catching or discomfort. Precision prongs cradle the marquise’s sharp points, protecting its architectural form while maximizing light reflection.

Our lab-grown diamonds offer the clarity and brilliance of mined stones with a lighter environmental footprint, reflecting a commitment to ethical jewelry without compromise.

The elongated marquise shape visually lengthens the hand, ideal for those who appreciate a refined yet distinctive silhouette. Its three-stone design balances presence with subtlety, making it equally suited for stacking alongside a wedding band or worn solo as a statement of quiet romance.

Should you need a custom fit, resizing is handled expertly in-studio to maintain the ring’s integrity and comfort.
