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.

Charoite is newly found mineral, first discovered in the 1940s and described to the world in 1978. It is found only in Siberia, Russia and is a translucent lavender to purple color.  Charoite has a swirling, fibrous appearance and is strictly massive in nature. It is used as an ornamental stone and sometimes as a gemstone.

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.

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.

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.

Rhodocrosite is a Manganese Carbonate mineral.  It is typically a rose-red color, but impure specimens can be shades of pink to pale brown.  It is used as a key component of low-cost stainless steel and certain Aluminum alloys.  Quality banded specimens are often used for decorative stones and jewelry, although it is relatively soft and difficult to cut.

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.

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.

Onyx is a banded variety of Calcite.  The colors of its bands range from white to almost every color except shades of purple, blue and black.  It is used for vases, bowls, beads, cabochons and other items.  This type is found in Mexico and Pakistan and is often carved and polished into various items.  This material is much more readily available and softer than the gemstone commonly called Black Onyx which is a silica gem.

Chert is a fine-grained silca-rich sedimentary rock that may contain small fossils. It varies greatly in color, but most often manifests as gray, brown, grayish brown and light green to rusty red; its color is an expression of trace elements present in the rock, and both red and green are most often related to traces of iron.
