Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, luminous shadow that dances across the hand. This semi-set engagement ring foundation in 14K white gold awaits your choice of a 10 x 5 mm marquise center stone, designed to highlight the gem’s tapered drama and elegant elongation.

Each band is meticulously crafted in our Williamsburg studio, where the cool gleam of white gold is hand-finished to a smooth, comfort fit that sits low against the finger. The setting’s artisan accents frame the center stone with subtle texture, offering a refined balance between bold geometry and delicate craftsmanship.

Our commitment to ethical jewelry is reflected in the exclusive use of lab-grown diamonds, ensuring clarity and brilliance with a lighter environmental footprint.

Ideal for those who appreciate a sleek profile that layers effortlessly with wedding bands or stackable rings, this mounting suits slender to medium finger shapes, enhancing the hand’s natural grace without overwhelming it.

Should you need resizing, our in-house experts provide precise adjustments to maintain the ring’s integrity and comfort.
