Mineral ID

Welcome to the mineral and fossil ID section. This ID chart is designed to be used as a reference for our mineral and fossil mystery bags. Your mystery bag will contain up to 20 different specimens. Thank you for your support and we look forward to seeing you this year at the shows.



Aventurine is a form of quartz, characterized by its translucency and the presence of platy mineral inclusions that give it a shimmering or glistening effect termed aventurescence



Amethyst is a violet variety of quartz.



Aquamarine is a pale-blue to light-green variety of beryl. The aquamarine has a chemical composition of Be₃Al₂Si₆O₁₈, also containing Fe²⁺. It has a hardness of 7.5 to 8. Aquamarine contains no or little noticeable inclusions.


Apatite Teal

Apatite is the name of a group of phosphate minerals with similar chemical compositions and physical properties. They are an important constituent of phosphorite, a rock mined for its phosphorus content and used to make fertilizers, acids, and chemicals.

Chalcedony Rose

Chalcedony Rose occurs in the form of slender and comes with a smooth curved face. Chalcedony Rose is a semi-transparent/translucent gemstone belonging to quartz according to the structure and the category of the crystal that has.


Citrine Quartz

The citrine stone is the yellow to reddish-orange member of the crystalline quartz family.

Coral Agate - Florida

A rare type of mineralized fossil consisting of a variety of fine-grained crystalline quartz called chalcedony, agatized coral was chosen by the state legislature in 1979 as the Florida state rock. These fossils can be found in several areas in the state, and are highly sought after by collectors.

Feldspars are a group of rock-forming aluminium tectosilicate minerals, containing sodium, calcium, potassium or barium. The most common members of the feldspar group are the plagioclase (sodium-calcium) feldspars and the alkali (potassium-sodium) feldspars. ... Feldspars are also found in many types of sedimentary rocks.

Green Agate

Agate variety of quartz with inclusions of Chlorite and other minerals which give it the green color.



Labradorite is a calcium-enriched feldspar mineral first identified in Labrador, Canada, which can display an iridescent effect. Labradorite is an intermediate to calcic member of the plagioclase series.

Optical Calcite

Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO3). A clear cube also known as Iceland Spar.

Orange Calcite.jpg

Orange Calcite

Orange calcite is a rock-forming mineral that's found in many different countries. It is a carbonate mineral that comes in a range of different shades.



Pyrite is an iron sulfide mineral with a metallic luster.
It has and a brassy coloring that is similar to gold, because of this resemblance it is also known by the name Fools Gold. It comes from the cubic crystal system and has an opaque transparency and a brittle texture.

petrified wood.jpg

Petrified Wood

 The name given to a special type of fossilized remains of terrestrial vegetation. Petrifaction is the result of a tree or tree-like plants having been replaced by stone via a mineralization process that often includes permineralization and replacement.

qtz crystal.jpg

Quartz Crystal Points

Quartz is a hard, crystalline mineral composed of silica. The atoms are linked in a continuous framework of SiO₄ silicon-oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO₂.

rose qtz.jpg

Rose Quartz

Rose Quartz is a pink form of quartz. It is also known as Hyaline Quartz. It has a pale pink coloring and a translucent transparency and a vitreous luster. Rose Quartz is the stone of universal love.

Septarian specimens are geodes that are a combination of yellow calcite, brown aragonite, grey limestone and white or clear barite. ... Eventually, bentonite is replaced with limestone, resulting in the nodule turning to stone.



Sodalite is a royal blue tectosilicate mineral with the formula Na ₈Cl ₂, widely used as an ornamental gemstone. Although massive sodalite samples are opaque, crystals are usually transparent to translucent. Sodalite is a member of the sodalite group with hauyne, nosean, lazurite and tugtupite.

shark teeth.jpg

Shark Teeth Fossil

Sharks lose up to 35,000 teeth a year depending on the species. Most fossil teeth are more than 10,000 years old.  A tooth will fall out of a shark's mouth and is buried in the ocean floor. This will naturally preserve the tooth, keeping it safe from oxygen and bacteria that can lead to decomposition. The dark colors of a shark tooth fossil come from absorbing minerals found in the ground around them.

Tumbled Stones Variety

A variety of tumbled semi precious gemstones randomly chosen from our inventory.
