Lab-Grown Diamond Engagement Ring

Light catches the elongated points of a marquise diamond, casting a subtle, tapered glow that draws the eye along the finger. This three-stone semi-set engagement ring in platinum offers a refined balance of presence and practicality, designed to sit low and close for everyday comfort.

Crafted in platinum, the mounting features a secure, low-profile setting that minimizes snagging while maintaining the diamond’s dramatic silhouette. Each prong is hand-finished to a smooth, tactile feel, ensuring the band wears comfortably beneath gloves or stacked with other rings.

The center marquise, measuring 9 by 4.5 millimeters, brings a distinctive architectural elegance, its shape elongating the hand with a graceful, modern edge. The side stones frame the center with subtle brilliance, enhancing the overall light play without overpowering the design.

Lab-grown for clarity and ethical sourcing, this ring reflects a commitment to sustainability without compromising on the diamond’s natural fire and scintillation.

Ideal for those seeking a statement piece that integrates seamlessly into daily life, its comfort fit and low profile make it well-suited for active hands and layering with wedding bands.

Resizing is straightforward, handled in-studio with care to preserve the integrity of the setting. Typical lead times accommodate custom adjustments and ensure a precise fit.
