Product Description

The Classic. Perfected.

A round brilliant lab-grown diamond — the most light-returning diamond shape ever created — held by four delicate prongs above a 1.5mm plain band so refined it nearly disappears. No pavé. No halo. No distractions. Just the diamond, doing what diamonds do best: catching every light in the room and holding every eye in it.

This is the round solitaire in its purest, most timeless form.
