Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a subtle, tapered glow that draws the eye along the finger’s natural line. This three-stone semi-set engagement ring in 10K yellow gold offers a refined foundation for a 7 x 3.5 mm marquise center, designed with a low-profile setting that keeps the silhouette sleek and unobtrusive.

Crafted in Williamsburg, the band’s gentle curve and secure prong work ensure comfort for everyday wear without sacrificing elegance. The warm hue of 10K yellow gold complements the diamond’s brilliance while maintaining a durable, lightweight feel. Each piece undergoes meticulous finishing and inspection in-studio, balancing technical precision with artisanal care.

Choosing a lab-grown diamond here aligns with a commitment to ethical jewelry—minimizing environmental impact while delivering clarity and sparkle. The ring’s modest height and smooth edges make it glove-friendly and ideal for stacking alongside wedding bands or personal favorites.

Should you need adjustments, resizing is straightforward, handled with the same attention to detail that shapes every custom design. Lead times reflect our dedication to handcrafted quality, ensuring your ring is made thoughtfully and to exacting standards.
