Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curve of a marquise diamond, casting a slender, dramatic silhouette across the hand. This semi-set halo engagement ring in platinum frames a 10 x 5 mm marquise center with a delicate halo that amplifies its tapered drama without adding bulk.

Crafted in platinum for enduring strength, the mounting features a low-profile setting designed to sit comfortably beneath daily gloves and jewelry layers. Each prong is meticulously finished to secure the stone while maintaining a sleek, architectural line that complements the marquise’s pointed ends. The halo’s pavé diamonds are hand-set to enhance sparkle without compromising wearability.

Our commitment to sustainability is reflected in the use of a lab-grown diamond, offering clarity and brilliance with a lighter environmental footprint.

This ring suits those who appreciate refined geometry and a confident yet understated presence on the finger. Its comfort fit and modest height make it ideal for stacking or solo wear, especially for hands that favor elongated shapes.

Resizing is available to ensure a precise fit, with lead times tailored to maintain craftsmanship quality.
