Lab-Grown Diamond Engagement Ring

When light catches the elongated points of the marquise, it carves a silhouette that feels both bold and intimate. This semi-set halo engagement ring foundation in 14K rose gold frames an 8 x 4 mm marquise diamond with a delicate embrace, designed to highlight the stone’s tapered drama without overwhelming the finger.

Crafted with a low-profile halo setting, the band sits close to the hand, easing daily wear and minimizing snagging. The warm blush of rose gold complements the marquise’s fiery brilliance, while expert finishing ensures a smooth comfort fit that balances elegance with practicality.

Each piece begins with a lab-grown diamond, chosen for its clarity and ethical origin, reflecting a commitment to sustainability without compromise on sparkle.

This mounting suits those who appreciate a refined statement—elongating the hand with a slender silhouette and offering a versatile base for a custom center stone. Its subtle halo adds dimension while maintaining a sleek profile, ideal for stacking or solo wear.
