Not Your Daddy’s Palm Root!


Petrified palm root can be found anywhere palm trees once grew, from the California desert to Texas in the U.S.A., and all around the world.  Like any petrified or fossilized wood, the most common replacement is agate.

Swirling away from petrified palm roots kissing cousin, petrified palm wood, the root fossilizes with swirls and orbs of root, in an array of colors far from what the wood portrays.  Most root out there seems to become petrified by agate, while the wood I have worked with has a harness closer to opalite.  (Palm wood is one of the exceptions to the above agate replacement).

Petrified palm root is known to be mainly shades of grey and brown, with some red swirls, but when I saw this slab, I immediately saw purple hues, with many more shades of red in the swirls than normally found. 

I picked this slab up at a rock show in San Diego for a measly $3.00 over 10-years ago and cut the cab above the same day.  I was well pleased with how it cut, and it polished as nice as any porcelain jasper. I had never seen such colors in palm root before, and haven’t seen it since.  I will say, this was $3.00 well spent!!

The slab was marked “Lake Havashu Port”, and I am assuming that it originates from somewhere near Lake Havasu, Arizona. (Havashu could easily be a mis-spelling of Havasu).
  
The cab measures 1 5/8-inches tall by 7/8-inches wide, and 1/8-inch thick.

The slab measures 7-inches by 4-inchs, and 3/16-inches thick. 


Wyoming Youngite

The first time I laid eyes on Youngite, I was in lapidary love.  This is an amazing stone, and in all my years collecting, I have only seen a few small samples for sale! 

Youngite is a now extinct (no longer mined/mined out) brecciated jasper suspended in agate from Wyoming, near Guernsey.  The jasper breccia ranges in color from tan, peach and salmon while the agate chalcedony ranges from white to bluish grey.  Many times the formations are coated with druzy quartz, making amazing cabinet display pieces. 

The agate chalcedony fluoresces green, adding its appeal to not only agate and jasper collectors, but fluorescent mineral collectors.  In fact, it is one of the few  fluorescent, cab-able materials that I know of that has such a stunning appearance outside of it’s fluorescent appeal. 

Youngite formed in bytroidal clusters giving it the distinct look of stalactites when slabbed, similar to rhodochrosite or malachite formations.

The location Youngite hales from is completely mined out and new material is no longer available.  The few collectible pieces out there are demanding a high premium, and cab quality specimens are almost impossible to find.


Details:

Youngite is Wyoming’s state rock

Hardness:  7

Fluoresces green

Polishes to high gloss

Extinct material

Uses:  Collector grade specimens and cab quality gemstones




This display slab is polished to a high shine and measures 4-inches wide by 2 5/8-inches high, and is cut just over 1/8-inch thick.  This slab is cabbing grade material, but as it is already polished on the face, and I have no more material to cut, it is staying in my cabinet collection for now.
