Lab-Grown Diamond Engagement Ring
Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, luminous beam that seems to stretch beyond the finger. This semi-set engagement ring invites you to select a 12 x 6 mm marquise stone, known for its dramatic taper and graceful presence.
Crafted from 14K rose gold with a white gold accent band, the ring balances warmth and coolness in a subtle, refined way. Its low-profile setting ensures the stone sits close to the finger, minimizing snagging and enhancing everyday comfort. The delicate accent stones frame the center with quiet brilliance, while the band’s smooth finish speaks to meticulous hand polishing and inspection in our Williamsburg studio.
Each diamond is lab-grown, offering a clear, sustainable alternative that aligns with thoughtful craftsmanship and environmental mindfulness.
Designed for those who appreciate a sleek silhouette and a ring that wears effortlessly, this piece suits slender to medium finger shapes and layers well with wedding bands or stackable rings. Its secure setting and comfort fit make it a natural choice for daily wear without compromise.
