Lab-Grown Diamond Engagement Ring

Light catches the elongated points of the marquise diamond, casting a delicate silhouette that seems to dance with every movement. This three-stone engagement ring, set in cool platinum, frames the 7 x 3.5 mm center stone with two smaller companions, creating a subtle narrative of balance and grace.

Each diamond is carefully secured in a low-profile setting, designed to sit comfortably against the hand without catching on daily fabrics. The platinum band is polished to a satin finish, offering a quiet contrast to the diamond’s sharp brilliance, while the smooth comfort fit ensures wearability from morning coffee to evening strolls.

Crafted in Williamsburg, this ring features a lab-grown marquise diamond, chosen for its ethical clarity and sustainable origin—reflecting a commitment to responsible luxury without compromise.

Its slender shape and three-stone design suit those who appreciate refined geometry with a whisper of vintage romance, especially flattering on slender fingers or when paired with stackable bands. The low profile makes it glove-friendly and ideal for everyday wear.

Should you need a custom size, resizing is handled expertly in-studio to maintain the integrity of the setting and band.
