Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it reveals a subtle drama that draws the eye along the finger’s natural line. This semi-set platinum engagement ring offers a refined foundation, ready to showcase a 10 x 5 mm marquise center stone with delicate accent details that enhance its shape without overwhelming.

Crafted in platinum, the band is engineered for everyday wear with a low-profile setting that sits close to the finger, reducing snagging and ensuring comfort. The precise finish highlights the cool sheen of the metal, while the accents are carefully placed to complement the marquise’s tapered points, balancing brilliance with structural integrity.

Each diamond is lab-grown, reflecting a commitment to ethical sourcing and sustainability without compromising on clarity or sparkle.

Designed for those who appreciate a sleek silhouette, this ring suits slender to medium finger sizes and pairs effortlessly with stackable bands or a wedding band of your choice. Its comfort fit and modest height make it glove-friendly and ideal for daily life.
