Fluorite, also referred to as fluor-spar, is a mineral composed of Calcium Fluoride. It is a widely occurring mineral found world wide and is often found with metallic minerals such as Galena, Sphalerite, Barite, Quartz and Calcite. Fluorite may fluoresce strongly in ultraviolet light which may be due to the presence of some impurities such as Yttrium. Blue is the most common color but red, purple, green, yellow and white are also frequent. It can be used in high performance telescopes, camera lens, enamels and in the making of opalescent glass.

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.

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 give 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.

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.

Dry Head Agates are from the Bighorn Canyon area of Montana. The banding colors are usually bright orange with some white or pink bands on charcoal, light gray, whitish oranges or greenish matrix. Dry Head Agates are very rare and no longer available as the mining area is now part of a wild horse refuge. Dry Head Agates may be geologically similar to the Teepee Canyon and Fairburn Agates of the Black Hills area.

Carnelian is a red or reddish-brown variant of Chalcedony but also may come in the colors of orange and pink.  It is quite common and usually found in translucent pebble form.  It is found in several areas of Europe, Iceland and Madagascar.

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 of Onyx is found in Mexico and Pakistan.  It is often carved, polished and sold in a variety of different things.

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.

Lodalite is a type of quartz, with indeterminate minerals. It is also known as Garden or Shaman Quartz when cut and polished. The included minerals within lunar landscape. Lodalite Quartz offer a window into another world.

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.

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.

Amethyst is a purple variety of Quartz often used as an ornament. It occurs in color from a light, slightly pinkish violet to a deep grape purple. Upon exposure to heat, Amethyst generally becomes yellow, which some refer to as Citrine or "burnt" Amethyst. It is widely distributed as a mineral, but fine, clear specimens that are suitable for cutting as ornamental stones.

Agates mostly occur as nodules in volcanic rocks or waters containing Silica in solution which is 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.  It is very unlikely that you would ever find an exact duplicate of any type of Agate, Brazilian or other.

Peacock Marble is from Southwest China and formed in Limestone by heat and pressure in the earth's crust. Recrystallization during Himalaya formation caused the limestone to change in texture and makeup. Fossilized materials along with it's original carbonate minerals, recrystallized and formed large, coarse grains of calcite. Impurities present in the limestone during the recrystallization affected the mineral composition of the marble.  The minerals that result from the impurities give the marble up to ten different colors. The corresponding colors and minerals that can be found: Green - Serpentine; Purple - Manganese spar; Brown - Iron; Gray - Silicon Dioxide; Red - Hematite; Orange - Iron; White - Calcite; Violet - Iron Manganese; Yellow - Limonite; Blue - Copper, Cobalt, Chromium; Black - Carbon, Iron, Manganese. Peacock Marble is also called "seven color Jade" in local language.

A member of the evaporite group of minerals and the soft rock comprising anhydrite formed by precipitation of calcium sulfate from evaporation of seawater. Anhydrite can also form through the dehydration of gypsum, another sulfate mineral found in evaporites. Anhydrite may occur as a cap rock above salt domes.
