I purchased a beautiful, large, veined marble rock fountain, basin, and pump from Earth 2 Art Studio in Greenbank last year and had it delivered to my land in Langley. If I remember correct, the couple who own Earth 2 Art told me they sourced the marble from a river in Eastern WA. The fountain was never installed - it's just been sitting there, waiting for installation (basin and pump covered). I've attached the one photo I have of the marble, though it doesn't give a sense of size or of how absolutely pretty it is once it's running. The basin is 48" x 48" x 12". The rock is ~25" high and 31" in diameter at its widest point, and the water has this beautiful bubble up/drip/trickle down effect - something good for a lot of different birds and insects to drink from.
Our plans have since changed and we're now selling our property, so I'll be selling the fountain. :( I paid $2600 for all of it - obviously I'm not looking for anything near what I paid. You'll need to have a way to move it all - that's obviously the catch.
