Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curve of the marquise diamond, casting a slender, luminous shadow that dances with every movement. This three-stone engagement ring, set in warm 14K yellow gold, frames a 6 x 3.5 mm marquise center with two gently tapering side stones, creating a quiet harmony of light and form.

Each diamond is carefully bezel-set to sit low against the finger, offering a sleek profile that slips comfortably beneath a glove or alongside a wedding band. The polished gold band is hand-finished in Williamsburg, its smooth interior shaped for a comfort fit that invites daily wear without fuss.

Crafted from lab-grown diamonds, this ring reflects a commitment to ethical sourcing and environmental mindfulness, embodying a modern approach to romance.

Its slender silhouette suits hands that appreciate subtle drama and refined geometry, while the three-stone design speaks to a narrative of past, present, and future. The marquise shape’s tapered points elongate the finger, enhancing elegance without overwhelming delicate proportions.

Should you wish to adjust the size, resizing is available through our Brooklyn studio with care to preserve the ring’s balance and finish.
