Dugway Geode Bookends
|
BK307b
This is a very large, above average quality, set of Dugway Geode
bookends. The set has a very good color mix and nice polish on one side
with grey felt in the middle and bottom. They measure 9 1/2" x 6 3/4"
x 4 1/2" with the Geode cavity measuring approximately 5 1/2" on each side.
A super set that would make a super gift!! Geodes are geological rock
formations which occur in sedimentary and certain volcanic rocks. They
are essentially rock cavities or vugs with internal Crystal formations or concentric
banding. The exterior is generally Limestone while the interior contains
Quartz Crystals and/or Chalcedony deposits. If the Geode is completely
filled with Crystal, being solid all the way through, it is then called a nodule.
The set weighs 11 lbs. 11 ozs.

Here is a very nice, above average quality set of Black Orthoceras
bookends. This set measures 8" x 6 1/4" x 2 1/4" and has a nice polish

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.
The set weighs 7 lbs. 11 ozs.

Here is a very nice, larger set of Septarian bookends. This set measures
9 1/2" x 5" x 3 3/4" with a nicely polished
front face. The set has lots of Brown Aragonite with contrasting
Yellow Calcite. This set is very cool indeed! 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.
They weigh 9 lbs.

the banded or striped formation.

Grab them quick before they are gone!! Quartz is the second most common
mineral in the Earth's continental crust. It is mainly composed of Silica
or Silica based minerals. Although Quartz is known by a variety of names,
the most important distinction between types of Quartz is that of
macro-crystalline, individual crystals visible to the unaided eye, and
micro-crystalline, where aggregates of crystals are only visible under high
magnification. There are many forms of Quartz including Chalcedony,
Amethyst, Citrine, and Carnelian which are results of mineral impurities or
heat treatments.
This set weighs 4 lbs. 2 oz.
