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.

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.

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.

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.

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.

Coral is built by secreting calcium carbonate skeletons. Hard coral is fossilized over millions of years.  It can be almost any color.  The stony Corals are often found in Coral reefs, large structures generally found in tropical waters.  Reefs are extremely diverse consisting of over 4,000 species of fish, cnidarians, mollusks, crustaceans, and other animals.

Chrysocolla is of secondary origin and forms in the oxidation zones of copper ore. Some associated minerals are Quartz, Limonite, Azurite, and Malachite and Chrysocolla is often confused with Turquoise as they are similar in color. It gets it's name from Greek chrysos "gold" and kolla "glue".  It is known among Native American cultures as a healing stone and said to promote calm and level headedness.

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.

Obsidian is a type of naturally-occurring glass formed as an extrusive igneous rock.  It is produced when felsic lava erupted from a volcano, cools rapidly through the glass transition temperature and freezes without sufficient time for Crystal growth.  Because of the lack of Crystal structure, Obsidian blade edges can reach almost molecular thinness, leading to its ancient use of projectile points (arrow heads), and its modern use as surgical scalpel blades.

It is often the result of the weathering of Copper Ores and is commonly found with Azurite, Goethite and Calcite. It is typically associated with Copper deposits including Limestone which is the source of the Carbonate. Malachite is found in many regions world wide and is usually shaded green in color.

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.
