Galena

Galena, also called lead glance, is the natural mineral form of lead (II) sulfide. It is the most important ore of lead and an important source of silver. Galena is the official state mineral of Missouri and Wisconsin.
Calcite

Calcite is transparent to opaque and may occasionally show phosphorescence or fluorescence. A small amount of manganese is enough to make it glow bright red under some wave lengths of ultraviolet light.
Trilobite

Trilobites are a fossil group of extinct marine arthropods that form the classic Trilobita. Trilobites form one of the earliest known groups of arthropods. The fossils of trilobite are found in a limestone shale. The trilobite is Wisconsin's state fossil.
Agate

Agate is a cryptocrystalline variety of silica characterized by its fineness of grain and brightness of color. Although agates may be found in various kinds of rock, they are classically associated with volcanic rocks and can be common in certain metamorphic rocks.
Amethyst

Amethyst is a violet variety of quartz often used in jewelry. Amethyst occurs in primary hues from a light pinkish violet to a deep purple. Amethyst may exhibit one or both secondary hues, red and blue. The best varieties of amethyst can be found in Siberia, Sri Lanka, Brazil, and the far East.
