Lab-Grown Diamond Engagement Ring

Imagine the subtle drama of a marquise diamond catching light as it elongates the finger with elegant precision. This semi-set engagement ring in warm 10K yellow gold offers a sleek foundation for an 8 x 4 mm marquise center, framed by delicate accent stones that enhance its architectural clarity.

Handcrafted in Williamsburg, the band’s smooth finish and low-profile setting ensure comfortable daily wear without sacrificing presence. Each piece undergoes meticulous inspection to balance modern minimalism with enduring structure.

Crafted with a lab-grown diamond, this ring reflects a commitment to ethical jewelry—minimizing environmental impact while maximizing brilliance.

Its slender silhouette suits those who appreciate refined geometry and a confident statement that remains understated. The design’s modest height pairs well with stacking bands and fits comfortably under gloves or sleeves.

Should you need resizing, our Brooklyn studio offers precise adjustments to maintain the ring’s integrity and comfort.
