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 halo engagement ring in platinum frames a 5 x 3 mm marquise center with a delicate ring of pavé stones, enhancing brilliance without adding bulk.

Crafted in platinum for enduring strength and a cool, luminous finish, the setting is designed with a low profile to sit comfortably beneath gloves and daily wear. Each prong is meticulously shaped to secure the pointed ends of the marquise, while the halo’s precision pavé adds sparkle without compromising smooth edges or comfort.

Our lab-grown diamonds offer the clarity and fire of mined stones with a smaller environmental footprint, reflecting a commitment to ethical jewelry.

The slim band and modest height suit hands seeking elegance without excess, ideal for stacking or wearing solo. The marquise’s tapered form elongates the finger, balancing boldness with refined wearability.

Resizing is available to ensure a perfect fit, with careful finishing to maintain the ring’s sleek profile.
