Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, dramatic shadow that draws the eye along the finger’s natural line. This semi-set solitaire ring invites you to select a 10 x 5 mm marquise center stone, whose tapered points and brilliant facets offer a striking balance of vintage allure and modern edge.

Crafted from warm 18K rose gold, the band is shaped and polished in our Williamsburg studio to a smooth comfort fit that feels like a second skin. The low-profile setting keeps the diamond close to the hand, making it ideal for everyday wear without sacrificing presence. Each curve and prong is meticulously finished by hand, ensuring a secure cradle that highlights the stone’s unique geometry.

Our commitment to ethical jewelry shines through the exclusive use of lab-grown diamonds, offering clarity and brilliance with a smaller environmental footprint.

Designed for those who appreciate artisan craftsmanship and subtle sophistication, this ring pairs effortlessly with stackable bands or stands alone as a statement of refined taste. Its slender shape complements a variety of hand sizes, especially elongating fingers with grace.

Should you need adjustments, resizing is available to ensure a perfect fit, crafted with the same care as the original design.
