The enamel on your teeth is rated as 5.5 on the commonly described scale of 1 to 10 (1-talc, 2-gypsum, 3-calcite, 4-fluorite,5-apatite, 6-orthoclase, 7-quartz, 8-topaz, 9-corundum, 10-diamond). You can bite apatite, but watch out for orthoclase or higher on the scale. Corundum is the substance that composes most non-diamond precious stones.
