Prehnite is a Phyllosilicate mixture of Calcium and Aluminum. Although it is not a Zeolite, it is often associated with them and with Datolite and Calcite, in veins and cavities of Basaltic rocks, sometimes in Granites, Syenites or Gneisses. The color varies from light green to grey to white to yellow or a mix of colors. It is translucent and was named after it's discoverer, Colonel Hendrik von Prehn.

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.

Aragonite is a Carbonate mineral that can occur in conjunction with Calcium Carbonates.  Aragonite differs from Calcite in the formation of the Crystal shapes which can be in lattice, crystal, columnar or fibrous in many different designs, shapes and sizes.  Aragonite will form in mollusk shells, oceans and salt water caves as inorganic precipitates called marine cements and speleotherms.  Ammolite is a form of Aragonite with impurities that make it iridescent and valuable as a gemstone.

Moonstone is a typical Potassium Aluminum Silicate with several commonalities with the Feldspar family.  It's name is derived from the visual effect or sheen that is caused by light reflecting internally and externally from the layer inclusions of different Feldspars.  Moonstone is closely related to Sunstone, Labradorite and Sodalite.

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.

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.

Vanadinite is a mineral belonging to the Apatite group of Phosphate minerals. It is one of the main industrial Ores of the metal Vanadium and a minor source of Lead. Vanadinite is relatively uncommon and is associated with Galena, Wulfenite, Limonite and Barite. It is usually bright red or orange-red in color although it may sometimes be brown, red-brown, grey, yellow or colorless.

Hemimorphite is a mineral that has been mined with Zinc and Lead ores and is associated with Smithsonite.  Some specimens will show a strong green fluorescence in short wave UV light and weak light pink fluorescence in long wave UV light.  This mineral can be found world wide.

Limonite is an ore consisting of a mixture of hydrated Iron Oxide-Hydroxide of varying composition of minerals such as Goethite, Lepidocrocite, or Jarosite.  It has been mined with Hematite as an Ore for the production of Iron. Limonite is heavy and has a yellow-brown color.  It is often used as the pigment ochre in many paints.

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.

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.
