Lab-Grown Diamond Engagement Ring

Imagine the delicate silhouette of a marquise diamond, its tapered points tracing a subtle arc that elongates the finger with quiet elegance. This semi-set halo ring in warm 14K rose gold frames a 9 x 4.5 mm center stone, ready to be chosen and set to your exact vision.

The band’s gentle curve and polished finish offer a comfortable, low-profile fit that slips easily beneath gloves or alongside other stackable bands. Crafted in our Williamsburg studio, the halo setting is meticulously hand-finished to catch light from every angle, enhancing the marquise’s signature brilliance without overwhelming its refined shape.

Each lab-grown diamond embodies a commitment to ethical sourcing and sustainability, reflecting a modern approach to fine jewelry without compromise.

This design suits those who appreciate romantic details paired with everyday wearability—its slender band and halo accent create a balanced statement that complements slender to medium finger shapes gracefully.
