Lab-Grown Diamond Engagement Ring

Imagine the quiet moment when light catches the soft, rounded corners of a 5 x 5 mm cushion diamond, its gentle glow framed by two smaller stones that echo its modern geometry. This three-stone semi-set engagement ring in platinum offers a refined balance of clarity and structure, designed to sit close to the finger with a low-profile setting that feels both secure and effortless.

Each piece is meticulously crafted in our Williamsburg studio, where the cool weight of platinum is hand-finished to a smooth comfort fit. The setting’s clean lines emphasize the cushion’s subtle vintage warmth while maintaining a contemporary minimalism that complements daily wear.

Choosing a lab-grown diamond means embracing a more sustainable path, with the same optical brilliance and ethical clarity as mined stones but a lighter environmental footprint.

Ideal for those who appreciate architectural elegance without excess, this ring pairs beautifully with stackable bands or stands alone as a confident statement. Its low profile ensures it slips easily under gloves or sleeves, making it a practical choice for everyday life.

Should you wish to adjust the fit, resizing is available to ensure the ring feels as natural as it looks.
