This opal specimen has an excellent violet color, and a somewhat unusual appearance. The host rock is brown and nondescript. The opal is, I believe, filling the cracks and surrounding what may have been a fossil plant of some sort. There is a pattern of vesicals which looks a bit like some dried weeds (internally), and this plant could have been opalized, and then the remaining cells could have disolved away. Lending evidence to my theory is a second area which does look like fossilized plant material (from the outside), with highlights of violet opal along its edge and penetrating transverse cracks in the wood. There are numerous bits and veins of the opal scattered on the matrix.
