17.6 gram Extremely RARE nice Green CHROMIUM Petrified Wood from Winslow ARIZONA

Chromium petrified wood from Arizona
This
piece of green petrified wood is from Winslow Arizona. This caught my attention
at the Tucson Mineral/Gem show. The vendor is from Show Low and said it’s green from the result of
chromium infusion in the agatization process. He said it comes from an
extremely small occurrence on the Navajo Reservation, and fetches
premium prices.
This Chromium (Green) Petrified Wood is one of the
rarest petrified woods ever discovered.  Only one truck load was
unearthed near Winslow, Arizona in the 1970’s and has now been dispersed
to “who knows where”.
By carbon dating, it has been determined
to originate from the Chinle formation, Triassic era – approximately 180
million years ago.  The specimen was once a conifer tree
(Araucarioxylon Arizonicum) which grew to about 200 feet in height with a
width of approximately 6 to 8 feet.  During the fossilization process,
the organic matter from this tree was replaced with the element Chromium
(Cr).  The agatization process resulted with in a natural mint green
color.
