• Option A, a set busy with layers thin dark bands of scallop patterning, with brown layers sweeping off of them.
  • Round flat reddish-brown sandstone coasters spread evenly over a table-top with similarly colored gravel beneath them.
  • An example coaster held in a hand for scale, the piece showing good scenic formations like rolling hills.
  • The back of the coaster, covered with a thin layer of cork padding.
  • A coaster held sideways to show it is a relatively thin slab of sandstone
  • Option B, a set with a bold dark iron band through it, with sweeping thin layers above like a sky, and hill-like scallops and darker pattern below.
  • Option C, a lighter-colored set with dark iron banding in scallop pattern along one edge, like a valley with hills on each side. The rest of the coaster has an elongated ringed oval shape that appears to grow larger and darker across each piece.
  • Option D, a set with more even tone, some thin dark bands snaking across the surface with curved layering coming off them, forming hill-like patterns. Two of the pieces have a dark iron band along the edge, with different rock on the other side of it that contains iron dendrites.
  • Option E, a set with excellent bubbly rounded forms and rings of color. Layers sweep across the top like sky, with round forms ringed in dark iron bands. There is a ridge across one coaster where it was cut unevenly.
  • Option F, a set with darker pattern of thin dark iron bands through it making forms that look like hills and mountains in asian art.
  • A coaster on a measuring mat, showing it measures a bit under four inches in diameter.

Sandstone is a porous rock that soaks up water, making it an ideal material for drink coasters—condensation easily absorbs into the rock without damaging it. I also like to use sandstone coasters as an accent piece under specimens in my mineral cabinets.

These sandstone coasters are made of Kanab Goldenstone sandstone sourced from an area near Kanab, just across the border in Arizona. Sandstone is a sedimentary rock composed of sand compacted and cemented together through geological processes, giving it a grainy texture. Dark bands running through the material are caused by iron.

Sandstone with distinct layering like this is often called ‘picture stone’ because the layers resemble a southwestern landscape (or, in the case of option C, the set kinda looks like a series of the last thing the dinosaurs saw before the asteroid impacted). It is often cut into flat slabs to best show the layering, and nicer pieces are even framed for display. These flat coasters display the scenic patterning well, with each set cut from adjacent material so that pieces match.
