Compared to Moissanite, cubic zirconia is substantially softer. Cubic zirconia scratches and abrades easily. This is why it loses its lustre after a relatively short time. Frankly, there simply is no comparison between cubic zirconia and Moissanite. Moissanite’s properties are far superior to cubic zirconia. Moissanite is one of the hardest and toughest known elements on earth, making it extremely resistant to scratching, chipping and breaking.
