Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender beam that dances across the skin. This semi-set halo ring in 14K yellow gold frames a 7 x 3.5 mm marquise center, its pointed ends drawing the eye along the finger with quiet elegance.

Crafted in Williamsburg, the band’s warm gold glow is polished to a soft sheen, complementing the halo’s delicate pavé setting that enhances the diamond’s fiery brilliance without overwhelming its refined shape. The low-profile mounting ensures everyday comfort, while the secure prongs cradle the stone with precision.

Each diamond is lab-grown, offering clarity and sparkle with a mindful footprint—an ethical choice that aligns with contemporary values without compromising beauty.

This ring suits those who appreciate a slender, architectural form that elongates the hand gracefully. Its halo setting adds subtle radiance, making it a versatile piece for stacking or solo wear, and its comfort fit accommodates daily life with ease.

Should you wish to adjust the size, resizing is straightforward and handled with care in our Brooklyn studio.
