Crystals, a beautiful gift from the earth! January 13 2013

Jan 11, 2013 Crystals or minerals are inorganic solids. They each have their own distinct properties. Their chemical composition and the internal arrangement of their atoms is what makes each one unique. Each Crystal has it's own particular vibration of a precise intensity. This vibration or energy attunes itself to other vibrations. Ie. Humans, animals, plants. There are over 2000 unique specimens of minerals on earth, with new deposits still being discovered. Let's review, a mineral is: Natually occurring A solid Is organic (mostly with a few exceptions) Has a fixed chemical formula Has an orderly crystalline structure Mineralogists group minerals into family groups based on their chemical composition or what they contain. The Dana System classifies minerals into eight different classes or families. Using this mineral classification system not only helps to organize the thousands of known minerals but it also helps us understand mineral formation. Native Elements Pure or single element group. Most minerals are made up of combinations of chemical elements. In this group a single element found in is pure form. Example carbon as diamond. Silicates This is the largest group of minerals. Silicates are made from metals combined with silicon and oxygen. There are more silicates than all other minerals put together. Examples are quartz and feldspars. Oxides Oxides form from the combination of a metal with oxygen. This group ranges from dull ores like bauxite to gems like rubies and sapphires. Sulfides Sulfides are made of compounds of sulfur usually with a metal. They tend to be heavy and brittle. Several important metal ores come from this group like the pyrite. Slufates are made of compounds of sulfur combined with metals and oxygen. It is a large group of minerals that tend to be soft, and translucent like this barite. Halides form from halogen elements like chlorine, bromine, fluorine, and iodine combined with metallic elements. They are very soft and easily dissolved in water. Halite is a well known example of this group. Its chemical formula is NaCl or sodium chloride commonly known as table salt. Fluorite is also in the halide family. Carbonates are a group of minerals made of carbon, oxygen, and a metallic element. Calcite known as calcium carbonate is the most common of the carbonate group. Phosphates are not as common in occurrence as the other families of minerals. They are often formed when other minerals are broken down by weathering. They are often brightly colored. Examples are turquoise and apatite. Mineraloid is the term used for those substances that do not fit neatly into one of these eight classes. They are glasslike amorphous structures. Opal, jet, amber, and mother of pearl all belong to the mineraloids. As we walk around our world, look closely at the minerals around us. Take in their energy. Think about the miracle in which they where created. Be grateful for this gift from the earth. *A special thanks and recognition to all of the great writers in this field. My information is a compilation of bits and pieces from the many books and online information out there. I am so grateful for all of the insight.*
