Lab-Grown Diamond Engagement Ring

Sunlight catches the subtle curve of a 6.5 mm round diamond, its facets poised to ignite with quiet brilliance. This five-stone semi-set engagement ring in 18K yellow gold offers a structured yet modern silhouette, balancing clarity with confident geometry.

Crafted in Williamsburg, the band’s smooth finish and low-profile setting ensure a comfortable fit for daily wear. Each prong is meticulously shaped to cradle your chosen center stone securely, while the side stones frame it with refined precision. The warm glow of yellow gold complements the diamond’s fire without overwhelming its natural sparkle.

Our commitment to sustainability shines through the use of lab-grown diamonds, offering exceptional clarity and ethical provenance without compromise. This ring’s design suits those who appreciate minimalist elegance with a tactile presence—its balanced weight and smooth edges make it ideal for stacking or solo wear.

Should you need resizing, our Brooklyn studio provides expert adjustments to maintain the ring’s integrity and comfort. Typical lead times accommodate custom stone selection and finishing, ensuring a personalized experience.
