Amethyst Bookends
Amethyst is a purple variety of Quartz often used as an ornament. Upon exposure to heat, Amethyst generally becomes yellow, which some refer to as Citrine or "burnt" Amethyst. It occurs in color from a light, slightly pinkish violet to a deep grape purple. It is widely distributed as a mineral, but fine, clear specimens that are suitable for cutting as ornamental stones.

Brazilian Agate Bookends
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.

Septarian Bookends
Septarians were formed during the Cretaceous period, 50 to 70 million years ago when the Gulf of Mexico reached what is now Southern Utah. Decomposing sea life killed by volcanic eruptions, had a chemical attraction for the sediment around them, forming mud balls. As the ocean receded, the balls were left to dry and crack. Because of their Bentonite content they also shrank at the same time trapping the cracks inside. The decomposed Calcite from the shells was carried down into the cracks in the mud balls, Calcite crystals formed. A thin wall of calcite was transformed into aragonite separating the Bentonite heavy clay exteriors from the calcite centers. Thus, the nodules are called Septarians. Septarians are composed of Calcite (The Yellow Centers), Aragonite (The Brown Lines) and the Outer Grey Rock is Limestone. Occasionally the fossil or some of the fossils which started the formation of the rock is noticeable in the rock.

Rose Quartz is a member of the Quartz family that exhibits a pale pink to a rose red hue, and sometimes will appear as a light lavender. The color is usually due to the trace amounts of Titanium, Iron or Manganese in the mass material. Some Rose Quartz contains microscopic Rutile needles which will produce an asterism in bright transmitted light. This material is an all time favorite with many rock lovers.

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.
