Specimen: Dome face polished, self collected Cady Mountains purple & white flame agate from California. This color and type combination is rare from this location, and this piece was collected many years ago. The back side is cut flat & could also be polished.
2 1/2″ x 1 3/4″ x 1 5/8″ thick
Specimen: A nice slightly dome face polished piece of gem silica, chrysocolla, malachite, and quartz. The gem silica is a beautiful aqua baby blue, and this piece could be cut into slabettes for cabbing. There are some tiny fractures in the lower part as seen in the photo. From Arizona.
2 1/8″ x 1 3/8″ x 1 1/2″
WT: 61.3 grams
Specimen: This is a rare and beautiful face polished agatized fossil pine cone section slab with exceptional color and pattern dating from the Jurassic period, approximately 180 million years ago. These Araucaria and Pararaucaria pine cones are among the best preserved pine cones in the world and are found in Patagonia, Argentina. Face polished on both sides.
2 7/8″ x 2″ x 3/8″
Specimen: This is a beautiful, fairly large, face polished fortification banded rough chunk of Agua Nueva agate from Mexico with euhedral quartz and other inclusions. It has a few sparkly druzy pockets, and would make an excellent addition for anyones agate collection.
4″ x 1 7/8″ x 1 5/8″
Specimen: This is an awesome, large, face polished collector slab of petrified wood from Arizona. There are a couple of small unpolished spots on the edges and it isn’t a complete round, but it’s close. I don’t know the type of wood that it is, and it has great little fortifications and other patterns throughout.
7 3/8″ x 6″ x 1/2″
Specimen: This is a nice face polished piece of Teepee Canyon agate from South Dakota. This piece has some bright red & orange fortifications around a small euhedral quartz center. There are some thin fracture lines across the face, but it could be easily cut a few more times for slabs for cabbing.
2 7/8″ x 2 5/8″ x 2 3/4″
Specimen: This is a standing, face polished display piece of an extremely unique and rare material called Myreckite. Myrickite is a type of agatized Cinnabar that was discovered in Death Valley, CA, back in 1911 by Shady Myrick in what later became the McLaughlin gold mine. To see additional information about Myrickite, the Rice Northwest Museum of Rocks & Minerals in Oregon has a permanent exhibit of this highly prized material.
2 3/8″ x 1″ x 1 1/2″
Specimen: This is a nice face polished Dryhead fortification agate from Montana. There is an open center surrounded by euhedral quartz and agate banding. There is one thin fracture in the banding as seen in the photo, but it is much less noticeable in hand. Great colors in this piece, and it is also dome polished on the back side.
2 7/8″ x 1 3/8″ x 3/4″
Specimen: This is a terrific little face polished Coyamito agate half nodule with orange & dark red bands in a purple background with pseudomorph inclusions & a small euhedral quartz center. Very hard to photograph – the line going across is a camera reflection! From Mexico.
1 1/2″ x 1 1/4″ x 3/4″
Specimen: This is a beautiful walnut-sized, glassy Tektite from Viet Nam. This specimen came from an old collection in the 1970’s and still has the old collection number on the bottom written in ink on white-out. It is fairly opaque and looks to be an almost black color.
1 1/2″ x 1 1/4″ x 1 1/8″
Wt: 32.8 grams
Specimen: This is an unusual piece of Fulgurite from the red hills of Sedona, Arizona. Fulgerites are created by lightning shooting into the earth and melting the surrounding soil into a tube shape that follows the form of the strike. For the metaphysical folks out there, this is a real prize!
