Probably not natural granite
After consulting with a chemist and a geotech engineer, and doing some testing, it appears this is probably not made of solid granite as advertised. It appears to be an aggregate of stone and binder. Rubbing pestle against mortar produces a fine grayish-green dust that smells like cement. The chemist recommended that this be used for non-food items only.
