1.0 ct round cut genuine Moissanite stone set in 6 prong low profile .925 sterling silver band. The stone is flawless, zero dings or scratches. I do not have the paperwork for it but the video shows it scores as a diamond when tested. The band has some light scratches to it, nothing visible unless your eye is right up against it. These are great stones to wear without worry and photos really don't do the sparkle justice.
