the denser the stone the less water it will absorb density = hardness the porous the stone the more water it will absorb

yes the denser the stone the harder the stone is. if the water gets absorbed into the stone that means the stone is porous not as dense as the other stone holding the water on top of the stone

checking for hardness do the water test put one drop of water on a few of your hardest stones which ever stone holds the water the longest is the hardest

the way i look at hardness is through density the more compacted the stone is the hard the stone will be the harder the stone the less of a cutter but it will be a better polisher
