Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a sleek, confident line. This semi-set three-stone engagement ring in 14K yellow gold offers a modern-minimalist expression of clarity and structure, framing your chosen center stone with two delicately balanced side gems.

Handcrafted in Williamsburg, the band’s smooth finish and low-profile setting ensure a comfortable fit for daily wear, while the secure prong work highlights the marquise’s signature brilliance without excess metal. Each piece undergoes meticulous inspection to meet exacting standards of craftsmanship.

Featuring a lab-grown diamond center, this ring reflects a commitment to ethical jewelry—minimizing environmental impact without compromising on radiance or durability.

The elongated marquise shape visually lengthens the finger, ideal for those seeking a refined yet striking silhouette. Its three-stone design offers versatility, pairing effortlessly with stacking bands or worn solo for understated elegance.
