Brazilian Agate Bookends

BK109b  This is a very pretty set of Blue (color enhanced) Brazilian Agate Geode bookends. The set measures 7 1/4" x 5 1/2" x 2 3/8" with a nicely polished front face and insides.  The set has a pretty Blue color and a very neat multi-colored center.

Agates mostly occur as nodules in volcanic rocks or waters containing silica in solution possibly derived from the decomposition of silicates in the lava.  The siliceous matter is deposited in regular layers resulting in the banded or striped formation.

The set weighs 5 lbs. 8 ozs.

Orthoceras Bookends

BK100b  Here is a very nice, above average quality set of Black Orthoceras bookends.  This set measures 8" x 6" x 2" and has a nice polish on the front, middle, top and side faces.  The bookends have been cut, carved and polished from Fossil Rock material to expose the very unique fossils.  This material is from Morocco.  The bookends make great decorator pieces as well as super collectibles for the fossil hunter.

Ammonites are an extinct group of marine animals of the subclass Ammonoida in the class Cephalopoda, phylum Mollusca.  They are excellent index fossils which are fossils that are used to define and identify geologic periods.  Ammonites' closest living relative is probably not the modern Nautilus (which they outwardly resemble) but rather the subclass Coleodiea, which are octopus, squid and cuttlefish.

The set weighs 7 lbs. 6 ozs.

Petrified Wood is a type of a fossil as it consists of fossil wood where all the organic materials have been replaced with minerals while retaining the original structure of the wood.  These minerals are most often Silicates such as Quartz.  Other minerals, Manganese, Iron and Copper, in the water or mud during the petrification process gives Petrified Wood a variety of color ranges: black - Carbon; green/blue - Copper; red/brown/yellow - Iron.  Petrified Wood can preserve the original structure of the wood in all its detail all the way down to the microscopic level.  Structures such as tree rings and the various tissues are often observed features.  Although Petrified Wood can be found worldwide, it is rather rare in larger quantities and at times can be difficult to obtain by the average collector.

Septarians are commonly composed of a carbonate mineral such as Calcite, a microcrystalline form of Silica as in Flint or Jasper, or an Iron Oxide such as Hematite.  These specimens are also known as a concretion which is a type of sedimentary rock. 

Septarians were formed millions of years ago by sediment forming around a fossil to create a mud ball transforming the fossil into Calcite and Aragonite.

Total weight 15 lbs.4 ozs.
