Description3.25 inches long 6.4 oz. Prehnite Quartz rare mineral specimen sec. b1 stock # 310zeolite24 Prehnite is a phyllosilicate of calcium and aluminium with the formula: Ca2Al(AlSi3O10)(OH)2. Limited Fe3+ substitutes for aluminium in the structure. Prehnite crystallizes in the orthorhombic crystal system, and most oftens forms as stalactitic or botryoidal aggregates, with only just the crests of small crystals showing any faces, which are almost always curved or composite. Very rarely will it form distinct, well individualized crystals showing a square-like cross-section, like those found at the Jeffrey Mine in Asbestos, Quebec, Canada. It is brittle with an uneven fracture and a vitreous to pearly lustre. Its hardness is 6-6.5, its specific gravity is 2.80-2.90 and its color varies from light green to yellow, but also colorless, blue or white. In April 2000, a rare orange Prehnite was discovered at the famous Kalahari Manganese Fields in South Africa. It is mostly translucent, and rarely transparent. Though not a zeolite, it is found associated with minerals such as datolite, calcite, apophyllite, stilbite, laumontite, heulandite etc. in veins and cavities of basaltic rocks, sometimes in granites, syenites, or gneisses. It is an indicator mineral of the prehnite-pumpellyite metamorphic facies. It is the first mineral to be named after someone, and was first described in 1789 for an occurrence in Haslach, Harzburg and Oberstein, Germany, and named for Colonel Hendrik Von Prehn (1733–1785),[1] commander of the military forces of the Dutch colony at the Cape of Good Hope from 1768 to 1780. Extensive deposits of gem quality Prehnite occur in the basalt tableland surrounding Wave Hill Station in the central Northern Territory, of Australia. All quartz crystals have 6 primary properties. They are able to structure, store, amplify, focus, transmit and transform energy, which includes matter, thought, emotion and information. Metaphysical quartz formations possess additional properties, based on their geometry and other specific features. Quartz "ice of the gods" Quartz naturally harmonises and energizes our gross and subtle bodies. Kirlian photography has shown that holding a small, double terminated quartz doubled the photographable portion of the aura. The chakras can be activated, cleansed, balanced and energized, and all psychic abilities can be initiated and strengthened. Quartz Alternate Names & Name Spellings: Rock Crystal Chemical Composition: SiO2 Hardness (Mohs): 7 Color(s): Clear, White, Pink, Brown, Gray, Black, Green, Blue, Orange, Purple (Amethyst), Yellow (Citrine) Lustre: Vitreous Transparency: Transparent, Translucent Habit: widely variable, trigonal-trapezohedral, crystals often columnar Common Locations: Found all over the world, most notably Brazil and Arkansas, USA. Rock Lore & Tidbits: Quartz is the most common mineral on the planet. It is a component of a huge variety of rock types, and comes in an extensive range of colors and varieties. Chalcedony is a crypto-crystalline variety of quartz and includes the agate and jasper families. Many colors of quartz or formations have their own names, such as amethyst for purple quartz. The word quartz is thought to come from the German word "quarz", but the origin of that word is not known. The word crystal, however, comes from the Greek word "krystallos" which means ice. Ancient Japanese believed quartz formed from the breath of a white dragon, and regarded it as representing perfection. Australian Aborigines used quartz in rain rituals. Crystals skulls were reportedly made by Atlanteans and are believed by some to be living entities. Clear quartz formed into spheres have been used as crystal balls to predict the future at least since the middle ages. Metaphysical and Healing Properties Lore Keywords: Power, Clarity Quartz is a power stone. It has been called the "Universal Crystal", and is the most recognized type of crystal. It's what many people envision when they think of crystals, even though there are many types of crystals. Quartz can be icy clear or have inclusions, veils, bubbles, etc. Visual clarity normally isn't important to a quartz crystal's energetic quality and ability to amplify subtle energies. Quartz enhances energy by absorbing, storing, amplifying, balancing, focusing and transmitting. It channels universal energy. Quartz also enhances thoughts, as they are a form of energy. Because it directs and amplifies energy, it is extremely beneficial for manifesting, healing, meditation, protection, and channeling. It is also beneficial for storing and retrieving information of all types, as information is a form of energy pattern also. This makes them particularly good for programming. Due to its ability to balance, quartz is excellent for harmonizing and balancing one's environment. Quartz is also good for energizing other crystals.
