Sapphire vs Diamond Engagement Rings
Sapphire engagement rings are having a moment. Here is how they compare on hardness, cost and style.
Hardness and Daily Wear
Sapphire rates 9 on the Mohs scale — second only to diamond (10). That means a sapphire ring survives daily wear nearly as well as a diamond. Blue sapphire is the classic; pink, yellow and padparadscha are rising. See our sapphire ring guide.
Cost and Color
A fine sapphire costs much less than a diamond of the same visual size, and the color is unique. Natural sapphires can be heated (normal and stable); ask if yours is untreated for premium pricing.
| Diamond | Sapphire | |
|---|---|---|
| Hardness | 10/10 | 9/10 |
| Look | White sparkle | Colorful, unique |
| Cost | Higher | Lower per carat |
