Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, dramatic shadow across the hand. This semi-set engagement ring invites you to choose a center stone that balances bold geometry with refined grace.

Crafted from warm 14K rose gold, the band is shaped and polished in our Williamsburg studio to a smooth, comfortable fit that rests lightly against the skin. The low-profile prong setting is designed to showcase the marquise’s distinctive pointed ends while ensuring everyday wearability without catching.

Each lab-grown diamond offers a clarity and brilliance that honors sustainable practices, reflecting a commitment to ethical jewelry without compromise.

This solitaire style suits those who appreciate architectural elegance and a statement that elongates the finger. Its slender band pairs effortlessly with stackable rings or stands alone with quiet confidence.

Should you need resizing, our in-house artisans provide careful adjustments to maintain the ring’s balance and finish.
