Moissanite vs Lab Grown Sapphire & Other White Stones
How moissanite stacks up against the other popular white gemstones.
Moissanite isn't the only brilliant white stone out there. Here's how it compares to white sapphire and a few other options, so you can see why it's such a popular diamond alternative.
Moissanite vs white sapphire
White sapphire is durable and beautiful but has a softer, more subtle sparkle; moissanite is harder and far more brilliant and fiery. See the full breakdown in Moissanite vs White Sapphire.
Moissanite vs cubic zirconia
CZ is inexpensive but soft and prone to clouding and scratching over time; moissanite is dramatically harder and keeps its sparkle for life. See Moissanite vs Cubic Zirconia.
Moissanite vs white topaz
White topaz is pretty but considerably softer, so it scratches and dulls more easily. Moissanite's hardness makes it far better for everyday rings.
| Stone | Hardness | Sparkle |
|---|---|---|
| Moissanite | Very high (~9.25) | Very high, fiery |
| White sapphire | High (9) | Subtle |
| White topaz | Moderate | Moderate |
| Cubic zirconia | Lower | High but dulls |
