Petrified Wood Bookends
The set weighs 3 lbs. 15 oz.
$90.00
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 give 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.
Brazilian Agate Bookends
The set weighs 7 lbs. 2 oz.
$60.00
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.

Stromatolite Bookends
The set weighs 8 lbs. 5 oz.
$65.00
Stromatolites are one of the oldest bacterial microfossils known. The Peruvian Stromatolites are from the lower Proterozic period some 2.3 billion years. They are from the Eastern Andes, Bolivia, South America.
Stromatolites are actually mounds of mud that have been preserved. Very few will actually contain the fossilized microbes that built them. They accumulate because blue- green algae produces a sticky film that catches mud and silt, in turn forming layers. In time theses layer build up to form mounds.
Orthoceras Bookends
This set weighs 8 lbs. 7 oz.
$32.00
Orthoceras is a genus of extinct Nautiloid Cephalopod. These fossils are common and have a global distribution which occur in any marine rock, especially Limestone. These are slender, elongated shells with the middle of the body chamber transversely constricted and a sub-central orthochoanitic siphuncle. The surface is ornamented by a network of fine lirae or fine lines/ridges.
Brazilian Agate Bookends
Total weight is 5 lbs. 9 oz.
$45.00
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.
Jasper Bookends
Total weight is 4 lbs. 13 oz.
$40.00
Jasper, also known as spotted stone, is an opaque, impure variety of Quartz that is usually red, yellow or brown in color. The mineral breaks with a smooth surface and is used for ornamentation or as a gemstone. It can be highly polished and is used for vases, seals, and other decorative items.
The set weighs 7 lbs. 13 oz.
$50.00
Rhyolite is an igneous, volcanic rock that is composed of Felsic, or Silicate minerals such as Silica, Aluminum, Sodium and Potassium. The material is similar to that of Granite, Pumice and Obsidian but due to the cooling process when formed, Rhyolite did not form any crystals, thus changing the texture of the material.
