We purchased some of this wonderful material at the Love the Art gallery in Beaver, Utah.
From what we understand the owners of the gallery are also the owners of the White Tiger Stone claim.
White Tiger Stone resembles Zebra Marble which is also found in Utah however the White Tiger Stone appears to be harder and has darker blacks and whiter whites than Zebra Marble. There are also some occasional gray stripes.
Update: Unfortunately the Love the Art gallery in Beaver has been closed.
