MOHs is the measure of hardness- a material's ability to be scratched. Durability is another matter. Agate is a cryptocrystalline quartz and measures about a 7.0 on the hardness scale. It's nearly identical to a jasper or chalcedony, though "agate" is the term given to a banded chalcedony. Chalcedony is more translucent/not banded (ie. Chrysoprase) and Jasper is the opaque variety. You'd be surprised how durable plain ol' agate really can be. Though, like anything else it can be damaged if done (im)properly. I'd be somewhat careful wearing such a ring.
