Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its pointed ends drawing the eye along a graceful arc. This semi-set three-stone ring invites you to select a 9 x 4.5 mm marquise center, framed by two delicate side stones that enhance its sculptural presence.

Crafted from 14K white gold, the mounting balances strength with refined elegance, its slender prongs holding each gem securely while allowing light to flood every facet. The band’s smooth finish and modest profile ensure comfort for daily wear, while the three-stone setting offers a quiet complexity that feels both modern and artisanal.

Each lab-grown diamond is chosen for clarity and brilliance, reflecting a commitment to ethical jewelry that respects both people and planet.

Designed for those who appreciate architectural form and subtle drama, this ring complements slender fingers and pairs effortlessly with stackable bands or a wedding band. Its low profile makes it glove-friendly and ideal for everyday life without sacrificing presence.
