Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it creates a striking interplay of brilliance and shadow that draws the eye along the finger’s natural line. This semi-set halo engagement ring foundation in 10K yellow gold offers a modern-minimal framework, designed to showcase a 9 x 4.5 mm marquise center with architectural clarity and confident structure.

Crafted with precision in Williamsburg, the band’s smooth finish and low-profile setting ensure comfortable daily wear without sacrificing presence. The halo setting, ready to embrace your chosen stone, adds a delicate frame that enhances the marquise’s tapered drama while maintaining a clean, contemporary edge.

Each piece reflects a commitment to ethical jewelry through the exclusive use of lab-grown diamonds, reducing environmental impact without compromising on clarity or fire. The warm glow of yellow gold complements the stone’s sharp facets, creating a harmonious balance between metal and gem.

Ideal for those who appreciate refined geometry and a ring that sits comfortably beneath gloves or alongside stackable bands, this design suits hands seeking both elegance and ease. Resizing is available to ensure a perfect fit, crafted with care in our Brooklyn studio.
