Colorado "smokey" quartz is found many places and sizes are very large at times.
This one being a large cabinet size piece.  Another fairly large piece (cabinet size) with an amazing combination of goethite.   And this 345 lb. monster crystal also found in Teller county Colorado.   Colorado smokey quartz also facets out very nicely!   Enjoy -------------------- CP-Owner/Administrator

Good question. But no, not magnetite.
Radiation when forming, and long term radiation from radioactive minerals, causes extra free silicon atoms to form, distorting the light. Amazonite gets it's color when Microcline(feldspar) forms with extra LEAD and Water, and is then bombarded by radiation. That is why Amazonite and Smokies are found together often. -------------------- Thankful member of COLORADO PROSPECTOR CLUB
