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.

Chevron or Banded Amethyst is a combination of Amethyst and White Quartz. This combination often forms a "V" or zig-zag design. 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.

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.

Jasper, or spotted stone, is an opaque, impure variety of Quartz that is usually red, yellow or brown in color.  Some Jaspers simultaneously exhibit several variants such as banding, flow patterns, dendrites or color variations.  This results in what appears to be scenes or images in a cut section of the Jasper.

Tiger-eye is a member of the quartz family, a cryptocrystalline variety.  It is one of the chatoyant varieties of gemstones.  Due to the fibrous structure of the gemstone, as light reflects within the thin parallel fibrous bands it exhibits a changeable silky luster or chatoyancy.  It occurs naturally in colors of gold and blue.

Fluorite, also known as fluor-spar, is a mineral composed of Calcium Fluoride.  It is a widely occurring mineral and is often found with metallic minerals such as Galena and Sphalerite, but also with Barite, Quartz and Calcite.  It may fluoresce strongly in ultraviolet light.  Although blue is the most common color, it can also be red, purple, green, yellow and white.

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.

Marble is a metamorphic rock consisting of Limestone but composed mostly of Calcite.  It is used extensively for sculpture, building materials and has many decorative uses.  The pure white Marble is probably the most common form known, but the characteristic swirls and veins of many colored Marble varieties are usually due to various mineral impurities such as Clay, Silt, Sand, Iron Oxides or Chert.

Zoisite is a Calcium Aluminum Silicate that belongs to the Epidote group of minerals. When it is found transparent, it is formed in to gemstones while translucent-to-opaque material is usually carved into sculptural works. The latter sometimes has Ruby Crystals which are completely opaque and unsuitable as gemstones, but are well colored and contrast strikingly against the green matrix of the Zoisite. Zoisite may be green, blue, brown, pink, yellow, gray or colorless.

Sodalite is a rich royal blue mineral enjoyed as an ornamental stone. Although massive samples are opaque, Crystals are usually transparent to translucent. It is very similar to Lapis but with out the Pyrite Crystals and distinguishable color differences. It makes great jewelry, cabochons an beads.

Calcite is a Carbonate mineral that is most widely distributed on the Earth's surface.  It is a common constituent of sedimentary rocks with Limestone in particular.  A Calcite formation can take on many different shapes and sizes which is dependent on the location, ground water occurrence and temperature.  Calcite is usually white or colorless but can be gray, red, yellow, green, blue, violet, brown or black.  The deeper the color is usually indicative of the definitive impurities from the earth or water.

Lepidolite is a lilac-grey or rose-colored member of the Mica group that is a secondary source of Lithium. It is one of the major sources of the rare alkali metals Rubidium and Caesium. Lepidolite occurs in Granite pegmatites, in some high temperature Quartz veins.

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 an ornamental stone, but fine, clear specimens that are suitable for cutting are used in jewelry.
