Lab-Grown Diamond Engagement Ring

Under the soft glow of Williamsburg light, a 4.5 x 4.5 mm square lab-grown diamond catches the eye with its precise geometry and quiet brilliance. This halo setting frames the center stone with a delicate circle of smaller diamonds, enhancing its architectural clarity without adding bulk.

Crafted in platinum, the band offers a cool, substantial feel while maintaining a low-profile silhouette that sits close to the finger. The setting’s refined construction ensures durability for everyday wear, with a comfort fit that balances presence and ease.

Each diamond is ethically sourced from a lab-grown origin, reflecting a commitment to sustainability without compromising on clarity or sparkle.

Designed for those who appreciate clean lines and subtle sophistication, this ring complements slender to medium finger shapes and layers effortlessly with stackable bands. Its low profile also makes it glove-friendly and unobtrusive for daily routines.

Should you need a custom size, resizing is straightforward thanks to the platinum’s malleability and expert studio craftsmanship.
