Geodes are geological rock formations which occur in sedimentary and certain volcanic rocks.  They are essentially rock cavities or vugs with internal Crystal formations or concentric banding.  The exterior is generally Limestone while the interior contains Quartz Crystals and/or Chalcedony deposits.  If the Geode is completely filled with Crystal, being solid all the way through, it is then called a nodule.

Lapis is a rock and not a mineral because it is made up from various other minerals.  To be a mineral it would have one constituent only, and Lapis has several including Lazurite, Sodium, Aluminum, Silicon, Oxygen, Sulfur and Chlorine.  Most Lapis contains Calcite, Sodalite and Pyrite.  The best color is an intense blue that is lightly dusted with small flecks of Pyrite.  Lapis takes an excellent polish and has been made into jewelry, carvings, boxes, mosaics and ornamental objects.

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.

Chalcedony is a cryptocrystalline form of silica, composed of very fine intergrowths of the minerals quartz and moganite.  Chalcedony has a waxy luster, and may be semitransparent or translucent. It can assume a wide range of colors, but those most commonly seen are white to gray, grayish-blue or a shade of brown ranging from pale to nearly black.

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.

A Meteorite is a natural object originating in outer space that survives an impact with the Earth's surface without being destroyed.  There are 3 types of meteorites: stony, which are mainly composed of Silicate minerals; Iron, which are largely composed of metallic Iron-Nickel; and stony-Iron, which are composed of both types of media.

Tourmaline is one of the most chemically complicated of all Silicate minerals. It is a complex Silicate of Aluminum and Boron and the composition varies widely with Sodium, Calcium, Iron, Magnesium, Lithium and many other elements that enter into it's structure. It can occur in a long, slender needle-like crystal to a thick prismatic and columnar crystal to a radial like daisy formation. It comes in many colors usually black and brown (iron rich); brown and yellow (magnesium rich); and blue, red, green, yellow, and pink (lithium rich). This mineral is found in igneous rocks, like Granite Pegmatite, and metamorphic rocks such as Schist and Marble.

Jasper, or spotted stone, is an opaque, impure variety of Quartz that is usually red, yellow or brown in color.  Some Jaspers simultaneously exhibit several variants such as banding, flow patterns, dendrites or color variations.  This results in what appears to be scenes or images in a cut section of the Jasper.

The term "shungite" was originally used in 1879 to describe a mineraloid with more than 98 percent carbon. More recently the term has also been used to describe shungite-bearing rocks, leading to some confusion. Shungite has to date mainly been found in Russia. Shungite has been used in medical treatment since the early 18th-century. "Peter the Great" set up Russia's first spa to utilize the water purifying properties of shungite and instigated its use in providing purified water for the Russian army. The anti-bacterial properties of shungite have been confirmed by modern testing.

Shungite is considered to be full of health benefits due to the natural fullerenes found within it. It detoxifies, acts as an anti-inflammatory, is antibacterial and antioxidant. Shungite protects against EMF frequencies and is fantastic to have near computers. Some even sell small flat pieces specifically to attach to cell phones and laptops. Shungite is being touted as a “must have” for those suffering from electrosensitivity. It is also said to rid negative emotional patterns.
