Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender beam that dances along the warm blush of 18K rose gold. This semi-set solitaire invites you to choose a center stone that echoes your unique story, its pointed ends lending a graceful drama to the hand.

Crafted in Williamsburg, the band’s gentle curve and polished finish ensure a comfortable fit for everyday wear. The low-profile mounting keeps the diamond close to the finger, making it glove-friendly and ideal for stacking with complementary bands. Each ring is meticulously shaped and inspected in-studio, reflecting a quiet precision in every detail.

Our commitment to sustainability shines through the lab-grown diamond option, offering clarity and brilliance without compromise. This ethical choice aligns with a modern approach to fine jewelry, mindful of both beauty and impact.

Designed for those who appreciate subtle romance and refined geometry, this ring suits slender to medium finger shapes, enhancing elongation while maintaining a delicate presence. The semi-set style allows for a personalized selection of a 5 x 3 mm marquise diamond, balancing architectural elegance with intimate craftsmanship.
