Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of this marquise center, casting a slender, luminous silhouette that gently elongates the finger. Crafted in warm 14K yellow gold, this three-stone engagement ring balances bold geometry with delicate artisan finish—each prong hand-shaped to cradle the 9 x 4.5 mm lab-grown diamond securely while allowing maximum light to dance through its facets.

The low-profile setting ensures the ring sits comfortably for daily wear, its smooth band designed with subtle tapering to complement the pointed shape without overwhelming. Finished with a meticulous polish, the ring reflects the quiet precision of our Williamsburg studio, where every detail is inspected before it leaves the bench.

Our lab-grown diamonds offer a clarity and brilliance that honors sustainability without compromise, embodying an ethical approach to fine jewelry.

Ideal for those who appreciate architectural elegance paired with a warm, tactile gold presence, this ring layers gracefully with other bands or stands strikingly alone. Its slender profile fits easily under gloves or sleeves, making it a versatile choice for everyday life.

Should you need resizing, our in-house artisans provide careful adjustments to ensure a perfect fit without disrupting the ring’s balance.
