Gems & Minerals

(jemz ǝnd min’ ẽr-ǝlz): Precious stones that have been cut and polished for use as jewelry or decoration and substances that occur naturally in rocks and in the ground and has a unique characteristic appearance and chemical composition.


In the game Twenty Questions, the first thing you ask is “Is it animal, vegetable, or mineral?” Well, it’s a good question, because anything that didn’t come from a plant or an animal probably came from a mineral. The bricks of your school building, the glass in your windows, the chalk you draw with- none would exist without minerals. Minerals are also essential in science and industry, for everything from computer circuits to diamond drills. Apart from their utility, beautiful and precious gems cut from mineral crystals give us pleasure to wear or just look at. Minerals are our most valuable and widely used natural commodities. We hope you will join us this year by entering your own gems and minerals in the 2010 Ventura County Fair. You will be proud to share these beautiful gems and minerals with the community and you may even win an award! The Gems and Minerals Department is presented by MillerLite.
