There are other, less expensive gems in a saturated deep blue, including. Kyanite, lapis lazuli, iolite and fluorite. But these are much softer stones that are not suitable for everyday jewelry such as rings. Blue topaz is unusual in offering excellent hardness (8 on the Mohs scale) and brilliance.
