Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, confident silhouette across the hand. This three-stone semi-set engagement ring in 10K white gold frames a 12 x 6 mm marquise center with two delicate side stones, emphasizing architectural clarity and modern minimalism.

Crafted in Williamsburg, the band’s smooth, low-profile design ensures daily comfort while the secure prong setting showcases the diamond’s dramatic shape without bulk. Each piece is meticulously finished by hand, inspected for precision, and polished to a soft sheen that complements the stone’s glassy brilliance.

Our lab-grown diamonds offer a transparent origin and a lighter environmental footprint, aligning with a quiet commitment to ethical jewelry.

The slender band suits those who appreciate refined structure and desire a ring that layers effortlessly with wedding bands or stackable accents. Its low profile fits comfortably under gloves and daily wear, ideal for hands that favor sleek geometry.

Resizing is available to ensure a perfect fit, with typical lead times tailored to your custom design preferences.
