Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of an 8 x 4 mm marquise diamond, casting a slender, fiery beam across the hand. This semi-set engagement ring invites you to select a center stone that balances dramatic taper with refined brilliance.

Crafted in warm 14K rose gold, the band is shaped with subtle artisan textures that catch light softly, enhancing the diamond’s pointed elegance. The low-profile setting ensures the ring sits comfortably for everyday wear, while delicate accent stones frame the center with quiet sparkle. Each piece is hand-finished in our Williamsburg studio, inspected for smooth edges and perfect symmetry.

Our lab-grown diamonds offer a clarity and sparkle equal to mined stones, with a lighter environmental footprint and ethical transparency.

The slender band suits hands that appreciate a graceful silhouette and pairs effortlessly with stackable rings or a wedding band. Its comfort fit and modest height make it glove-friendly and ideal for daily life.

Should you wish to resize, our Brooklyn studio provides expert adjustments to maintain the ring’s integrity without delay.
