Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a sleek 18K yellow gold band. This three-stone semi-set ring offers a modern-minimal statement, where clarity and architectural balance meet quiet confidence.

Crafted in Williamsburg, the ring’s low-profile setting ensures daily wearability without sacrificing presence. The warm glow of 18K yellow gold complements the marquise’s sharp geometry, while the semi-set design invites your choice of a 9 x 4.5 mm center stone, ready to be paired with two side stones for a harmonious trio.

Each piece is meticulously finished by hand, inspected for precision, and designed with comfort in mind—its smooth shank fitting naturally against the finger. The lab-grown diamond option reflects a commitment to ethical jewelry, reducing environmental impact without compromising brilliance.

Ideal for those who appreciate structured elegance and a ring that layers effortlessly with other bands or stands boldly alone. Its slender profile suits slender fingers and offers glove-friendly ease in cooler months.
