QUARTZ (clear)![]() OK, I was experimenting with my photography, like the experts do!! Sorry you have to endure a quadruple-sized finger! Ilk!
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 frequently is the primary mineral, >98%. It is also the most varied in terms of varieties, colours and forms. This variety comes about because of the abundance and widespread distribution of quartz. A collector could easily have hundreds of quartz specimens and not have two that are the same due to the many broad catagories. The specimens could be separated by answers to the following questions: colour?, shade?, pyramidal?, prismatic?, druzy?, twinned?, sceptred?, tapered?, phantomed?, inclusions?, coated?, microcrystalline?, stalactitic?, concretionary?, geoidal?, tappered?, banded?, etc. Multiple combinations of these could produce hundreds of unique possibilities. Hardness: 7. Other characteristics.
