Quartz
South Park, Park County, Colorado, USA
7.4 x 3.6 x 2.1 cm. This is an old Colorado specimen of "yellow quartz", which gets it very attractive color from inclusions. There is one large crystal, with several smaller ones leaning out from it. The crystals are transparent and sharp. This specimen came out of the collections of Edna Doughty to Richard Hauck.
