Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it draws the eye along a graceful arc, evoking subtle drama without excess. This semi-set engagement ring foundation in 18K rose gold offers a warm glow, ready to cradle a 6 x 3.5 mm marquise center stone with delicate accent settings that enhance its slender profile.

Crafted for everyday wear, the low-profile mounting keeps the diamond close to the finger, reducing snagging while maintaining a refined presence. The band’s smooth finish and balanced weight ensure comfort throughout the day, whether worn solo or stacked with complementary bands.

Each piece is meticulously inspected in our Williamsburg studio, where precision meets quiet artistry. The rose gold’s soft blush tone complements the marquise’s pointed ends, creating a harmonious frame that feels both modern and intimate.

Choosing a lab-grown diamond for this setting aligns with a commitment to ethical jewelry—minimizing environmental impact without compromising brilliance or clarity.

This ring base suits those who appreciate architectural elegance with practical design, ideal for hands that favor slender, elongated shapes. Its subtle accents add dimension without overwhelming the center stone’s unique form.

Resizing is available to ensure a perfect fit, and our team is happy to guide you through lead times and care recommendations.
