  2. Quartz • Chemistry: SiO2 , Silicon dioxide • Quartz is the most common mineral on the face of the Earth. • It is found in nearly every geological environment and is at least a component of almost every rock type. • It is also the most varied in terms of varieties, colors and forms. • Amethyst is the purple gemstone variety. • http://www.galleries.com/minerals/silicate/quartz/quartz.htm

  3. Feldspar • Feldspar occurs in igneous, metamorphic and sedimentary rocks and can be found throughout North Carolina. • Feldspar is the most common rock-forming mineral (about 60% of the earth’s crust). • Feldspar is used in the manufacture of glass products and in ceramics. • http://www.geology.enr.state.nc.us/Mineral%20resources/feldmod.html • http://csmres.jmu.edu/geollab/fichter/RockMin/Ortho-119.JPG

  4. Gold • Gold is one of the most popular and well-known minerals, known for its value and special properties since the earliest of time. • Gold nuggets, a popular form of Gold with collectors, are formed when erosion causes a large piece of Gold to separate from its mother rock, and then gets carried into a stream or river. • Due to its weight, it can be panned because the Gold sinks to the bottom. • http://www.minerals.net/mineral/elements/gold/gold1.jpg

  5. Ruby • Ruby is the red variety of the mineral corundum, one of the hardest minerals on Earth, of which the sapphire is also a variety. • For thousands of years, the ruby has been considered one of the most valuable gemstones on Earth. • The most important thing about this precious stone is its color. http://www.gemstone.org/gem-by-gem/english/ruby.html

  6. Emerald • Emeralds have been held in high esteem since ancient times. • The name emerald comes from the Greek 'smaragdos' via the Old French 'esmeralde', and really just means 'green gemstone'. • It is only seldom that a large emerald with good color and good transparency is found. • In top quality, fine emeralds are even more valuable than diamonds. http://www.gemstone.org/gem-by-gem/english/emerald.html
