Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated marquise diamond, casting a slender beam that dances with every movement. This three-stone engagement ring, set in cool 14K white gold, frames the 6 x 3 mm center stone with two delicate side diamonds, creating a quiet harmony of light and form.

Each gem is securely nestled in a low-profile setting, designed for daily wear without catching or discomfort. The polished white gold band curves smoothly beneath the finger, offering a subtle comfort fit that feels like a second skin. Expertly finished by hand in our Williamsburg studio, the ring’s refined edges and precise prong work reflect meticulous craftsmanship.

Our marquise center is lab-grown, embodying clarity and brilliance while honoring a commitment to sustainable, ethical jewelry practices.

Ideal for those who appreciate a slender silhouette that elongates the hand, this ring pairs effortlessly with stacking bands or stands strikingly alone. Its low profile ensures glove-friendly wear and ease in everyday life.

Should you need a custom size, resizing is straightforward and handled with care by our in-house jewelers.
