Lab-Grown Diamond Engagement Ring

Light catches the elongated points of the marquise shape, casting a slender, graceful silhouette that stretches across the finger. This semi-set solitaire ring in 10K yellow gold awaits your choice of a 9 x 4.5 mm marquise diamond, offering a refined balance between presence and subtlety.

Crafted with a low-profile setting, the band’s gentle curve ensures comfort for everyday wear while maintaining secure prongs that cradle the stone delicately yet firmly. The warm hue of the yellow gold complements the marquise’s vintage-inspired elegance, finished with a smooth polish that feels weightless against the skin.

Each diamond is lab-grown, reflecting a commitment to ethical sourcing and sustainability without compromising on clarity or brilliance.

Designed for those who appreciate a sleek silhouette, this ring suits slender to medium finger shapes and pairs effortlessly with stacking bands or wedding rings. Its low profile makes it glove-friendly and ideal for daily life without catching.

Should you need resizing, our Brooklyn studio offers precise adjustments to ensure a perfect fit without disrupting the ring’s clean lines.
