  1. Agate Geodes - Quartz

    Agate geodes are geological secondary structures which occur in certain sedimentary and volcanic rocks. They are themselves of sedimentary origin and naturally made by chemical precipitation. Geodes are hollow, vaguely spheroid to oblate masses of mineral matter. It may include crystals. They are excellent for grounding, working on the emotional, physical and intellectual levels and aid in centering and stabilizing physical energy.

  2. Agatized Rock - Quartz

    The term "agatized" refers to the variety of translucent chalcedony called "agate," which has very small crystals (micro- or cryptocrystalline), and is characterized by banding and rich coloration, properties that are common to agates. These 6 rocks were found in Jefferson County Montana.

  3. Amethyst Crystal - Quartz

    Amethyst is one of the most common--and popular!--gemstone materials. This variety of quartz ranges in color from deep purple to pale lavender depending on the presence of manganese and iron. These amethyst crytals were found at the PC Mine in Jefferson County Montana. Amethyst helps balance metabolism and positively serves the endocrine system, the body finds its inner harmony.

  4. Amethysts - Quartz

    Amethysts forms in long, prismatic crystals in geodes or hollow rocks. These geodes form when there are cavities in volcanic rock. As the rock cools, the mineral-saturated water, gases and volcanic material distil and crystallize. When these crystals harden, they form amethyst. Although generally more of a deeper purple, the stone can also have a reddish-purple tinge, or a very pale purple tinge that fades into a lilac. Amethyst is the most popul...

  6. Axinite Epidote - Limestone

    Epidote is a common mineral found in low to moderately regionally metamorphosed rocks. Epidote also occurs in contact metamorph limestone, especially near ore deposits. In granitic rocks Epidote is found in small fissures. Axinite is a brown to violet-brown, or reddish-brown bladed group of minerals composed of calcium aluminium boro-silicate, (Ca,Fe,Mn) 3Al 2BO 3Si 4O 12OH. These 4 rocks were found in Jefferson County Montana.

  7. Chalcopyrite - Copper

    Chalcopyrite, the most common copper mineral, a copper and iron sulfide, and a very important copper ore. It typically occurs in ore veins deposited at medium and high temperatures. The most obvious properties are its brassy yellow colour, metallic lustre, and high specific gravity. Although similar in appearance to gold, distinguishing these minerals is easy as gold is soft, has a yellow streak and has a much higher specific gravity. Chalcopyrit...

  8. Clear Quartz with Crystal - Quartz

    Clear quartz is perhaps one of the most popular and easily recognisable crystals around. Also known as clear quartz crystal, this stone is a mineral composed of oxygen and silicone atoms. It forms part of the trigonal crystal system and is classified as having a vitreous luster. As its name suggests, the rock is a transparent one. Other than appearing clear to the eye, this stone is also believed to bring clarity to those who carry it. It is also...

  9. Copper Ore - Copper

    Copper ore is typically found in the Earth's crust in the form of copper minerals, such as chalcopyrite, bornite, malachite, and chalcocite, among others. This copper ore was found on the Hallie Ferguson Mine on Cataract Creek in Jefferson County Montana. The copper ore was donated by Don Balser of Clancy Montana.

  13. Fluorite (Florspar) CaF2 - Fluorite

    Calcium Fluoride (CaF2), is also known as fluorite or fluorospar. It is a naturally occurring mineral that is transparent to translucent with colour varying widely from intense purple, to blue green, to yellow, through to reddish oranges, pinks, whites and browns. luoride (CaF2) is used in aluminium-metallurgy, brake lining, glass manufacturing, enamel and glazing frits production, and the production of welding agents and was found in Jefferson C...

  14. Garnets - Garnet

    Most garnet forms when a sedimentary rock with high aluminium content, such as shale, is metamorphosed (subjected to heat and pressure). The high heat and pressure breaks the chemical bonds in the rocks and cause minerals to recrystallis. These garnets were donated by Don Balser from Jefferson County Montana. Garnets are used for abrasive blasting granules, abrasive grits and powders, filtration granules, waterjet cutting granules and gemstones s...

    Green Tourmaline, also known as Verdelite, is a lithium rich crystalline boron silicate mineral and member of the Tourmaline family. Green Tourmaline moves healing energy throughout the body, bringing a sense of vitality and overall healthiness. It is used to encourage healthy sleep patterns, calm the nervous system and fight Chronic Fatigue Syndrome. This rock was found in Jefferson County Montana.

    The Japan Law is the only common twinning law of quartz where the two twin crystals are visible as individuals. In a Japan Law twin the c-axis of two crystals meet at an angle of 84°33', with two of the m prism faces of both crystals being parallel.This rock was found at the PC Mine in Jefferson County Montana.

  17. Jasper - Quartz

    Jasper is an opaque form of Chalcedony, which is a microcrystalline variety of the mineral Quartz. It often contains an abundance of impurities, and therefore some regard it as a rock instead of a mineral. These two rocks were found in Jefferson County Montana.

    Left three rocks are Jasper which is an opaque rock of virtually any colour stemming from the mineral content of the original sediments or ash. Patterns arise during the consolidation. Jasper is used for ornamentation or as a gemstone. The three rocks on the right are various agate which is almost always translucent (letting through some light when you shine a light on it) and have banding- thin visible layers. Often these bands form concentric r...
