Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of a hand, where a marquise-shaped diamond begins its quiet dance of light—tapered points catching every glance. This semi-set halo engagement ring in platinum offers a refined foundation for a 12 x 6 mm center stone, designed to sit close to the finger with a low-profile setting that balances presence and practicality.

Crafted in platinum, the mounting is meticulously finished for durability and comfort, its smooth shank easing into a comfort fit that suits daily wear without catching or bulk. The halo setting, once your stone is chosen, will frame the marquise with a delicate circle of smaller diamonds, enhancing its signature tapered drama while maintaining a sleek silhouette.

Each piece reflects our commitment to ethical jewelry: lab-grown diamonds provide exceptional clarity and brilliance with a significantly smaller environmental footprint. This ring’s design is ideal for those who appreciate architectural elegance paired with everyday resilience.

Its low profile and balanced proportions make it glove-friendly and stackable with other bands, especially flattering on slender to medium-width fingers. Resizing is available to ensure a precise fit, crafted in-studio with care and attention to detail.
