Petrified Wood Bookends |
BK600c
This is a very nice larger set of Sequoia Petrified Wood bookends from
Washington.
This set of bookends shows the growth lines in the wood very well and has a
very nice polish. They are polished on one side with black felt in the middle
and bottom. The set measures 12 3/4" x 7" x 2" and is an
awesome one-of-a-kind creation.
The set weighs 12 lbs. 7 ozs. $165.00 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. |

Orthoceras Bookends |
BK610b
Here is a very nice, above average quality set of Brown and Grey Orthoceras bookends.
This set measures 7 3/4" x 5 5/8" x 2 1/4" 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. 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. Total weight 7 lbs. 9 ozs. $42.00 |

bookends. This set measures over 7"x 5 1/4" x 3 1/8" with a polished front
face. The bookends have a nice Agate center and a couple tiny crystal
cavities. Something different
for the rock collector or make it a super gift. 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 6 lbs. 11 oz. $60.00 |

This is something different from the Rock Shed's gift department. Here
is an above average quality set of Bird's Eye Rhyolite bookends. This
material is from northern Mexico. The set measures nearly 9 1/4" x
6 3/4" x 1 7/8". Due to the nature of this material it does not have a high polish.
This material is a pretty Pink-Beige color with an interesting design
throughout the material.
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. The set weighs 5 lbs. 9 oz. $48.00 |

This set weighs 8 lbs. 2 ozs. $106.00 Jasper is an opaque, impure variety of Quartz that is usually red, yellow or brown in color.

Patterns can arise from the formation process and flow patterns in the sediment or volcanic ash that was saturated with silica which formed the banding or swirling designs in the rock |
