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.

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.
Labradorite Bookends
Total weight is 10 lb. 7 oz.
$120.00
Labradorite is a Feldspar mineral that occurs in large Crystal masses in anorthosite and shows an iridescence or "play of colors." Gemstone varieties of Labradorite exhibiting a high degree of iridescence are Spectrolite, Moonstone and Sunstone. High quality samples with good iridescent qualities are desired for jewelry.
Brazilian Agate Bookends
Total weight is 5 lbs. 8 oz.

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.

Silver Ore - Pyrite Bookends

Pyrite, or Iron Pyrite, is an Iron sulfide with isometric Crystals that usually appear as cubes. It is brittle and can break or powder easily. Its metallic luster and brass yellow hue have earned it the nickname of "fool's gold" due to many miners mistaken it for the real thing. Ironically, small quantities of actual gold are sometimes found in Pyrite. It is the most common of the sulfide minerals and is usually found with other sulfides or oxides in Quartz veins, sedimentary or metamorphic rocks.

Sandstone is a sedimentary rock composed mainly of sand size mineral or rock grains. Most Sandstone is composed of Quartz and/or Feldspar because these are the most common minerals in the earth's crust. It can be almost any color. The Sandstone beds often form highly visible cliffs and are strongly identified with certain regions of the world.

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.
