A specimen of petrified wood which has been replaced with Opal. Notably, one side is a green color. Other colors include black, varying shades of brown, white and various shades of yellow to yellow/orange. There is also some Chalcedony present in a few places on the surface including some small stalactic growths (sorry no picture of these - they are small and just noticed while writing the description). Under SW, some of the growth rings fluoresce green (sorry no photo).

Condition: Composed of massive material.

Flaws: Nothing Appreciable
