Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, luminous shadow that dances across the skin. This semi-set engagement ring invites you to choose a 6 x 3 mm center stone, its tapered points echoing a quiet elegance that feels both intimate and striking.

Crafted in warm 10K yellow gold, the band supports a delicate five-stone arrangement, each accent gem carefully positioned to enhance the marquise’s graceful profile. The low-profile setting ensures a comfortable fit for daily wear, while the smooth finish reflects the meticulous handwork of our Williamsburg studio artisans.

Each diamond is lab-grown, embodying clarity and brilliance with a mindful approach to sustainability. This ring’s slender shape and modest height make it ideal for those who appreciate subtle drama without bulk—perfect for stacking or wearing solo with ease.

Should you need a custom fit, resizing is handled with care to preserve the ring’s balance and integrity. Lead times are tailored to your chosen center stone, ensuring a thoughtful, pressure-free design experience.
