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.

$14.00 M801b  Here's a cool new item, a very nice Sweetwater Agate from Wyoming. It has an interesting shape and great change of color under LW and SW UV lights. It measures 2 1/4" x 2" x 1". It has been tumbled right here in our very own Lapidary Department and has a smooth texture and slight polish. Something very different!

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.

Kunzite, or a form of Spodumene is a pyroxene mineral consisting of lithium aluminium inosilicate, and is a source of lithium.  It occurs as colorless to yellowish, purplish, or lilac kunzite, prismatic crystals, often of great size.  Kunzite was discovered at the Pala Chief Mine near San Diego, California and named after gemologist GF Kunz, who first described it after the turn of the twentieth century.  Kunzite is an unusual and rare stone.

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.

Amber is the common name for the fossil resin or tree sap that is appreciated for its inherent and interesting mixture of color.  It is widely used for the manufacture of ornamental objects including jewelry.  Although it is not mineralized, it is sometimes considered and used as a gemstone.  Most of the world's Amber is in the range of 30-90 million years old.

A Ruby is a variety of the mineral corundum (aluminum oxide).  The color comes mainly from the chromium element.  The Ruby is considered one of the four precious stones, together with the sapphire, the emerald, and the diamond.  Rubies were found for centuries in Burma.  They have also been found in Thailand, Sri Lanka, Madagascar, Vietnam, Nepal and Pakistan.  Rubies have been found in the US states of Montana, North and South Carolina.

Barite or Baryte is a mineral consisting of Barium sulfate and is generally white or colorless. The baryte group consists of baryte, celestine, anglesite and anhydrite. Baryte commonly occurs in lead-zinc veins in limestones, in hot spring deposits, and with hematite ore.  It is used in the manufacture of paints and paper.  Although Barite contains a 'heavy' metal, Barium, it is not considered to be a toxic chemical because of its extreme insolubility.

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.
