There are two types porous and non porous. You can also seel porous concrete to make it non porous.
All natural store is porous and needs to be sealed. Travertine is the most porous over marble and granite
There is one called PORCERAX that is porous.
No it is not it has interlocking particles there fore is not porous

Silk is porous -- it absorbs liquids.
The rubies used to create fissure-filled stones are generally of very low quality. This kind of ruby is usually made more porous with an acid treatment. Then it is heated with other materials that make glass when the ruby gets hot enough. The glass fills in pits in the ruby. Therefore, parts of the stone are ruby, but parts are actually glass. Whether you consider this ruby "real" is up to you since parts are ruby, but depending on the size of the fissures that are filled, a significant part of the stone can be glass. The stones can be pretty, but glass does not have the same properties or hardness of a ruby.
Metal is not porous. Many other elements are porous though and when metal combines with them it can potentially become porous.
more porous
The story proved to be quite porous. Lava is a porous rock.

A sponge is very porous.
Some basalts can be quite porous, others may be non-porous.
Gunite is a type of sprayed concrete, and is basically as porous as concrete is.
