Lab-Grown Diamond Engagement Ring

When light catches the elongated points of a marquise diamond, it creates a striking silhouette that both sharpens and softens the hand’s natural lines. This semi-set platinum mounting awaits your choice of a 12 x 6 mm marquise center, designed to showcase the stone’s tapered drama with clarity and precision.

Crafted in platinum for enduring strength, the band features a low-profile setting that sits close to the finger, minimizing snagging while maximizing comfort. The solitaire design emphasizes the diamond’s shape without distraction, finished with a smooth polish that feels substantial yet unobtrusive for everyday wear.

Each lab-grown diamond chosen for this ring reflects a commitment to ethical sourcing and sustainability, offering the brilliance of mined stones with a reduced environmental footprint.

Ideal for those who appreciate architectural elegance paired with practical wearability, this mounting suits slender to medium finger sizes and pairs well with stackable bands or a wedding ring of similar profile. Its streamlined silhouette slips easily under gloves or sleeves, making it a discreet companion for daily life.

Should you need resizing, our Brooklyn studio offers precise adjustments to ensure a comfortable fit without compromising the setting’s integrity.
