Chalcopyrite with Sphalerite and Tetrahedrite (ex Al Kidwell Collection)

Item Description

An attractive association specimen of the classic material from Huaron. These pieces were all the rage with collectors a few decades ago, and they are certainly some of the finest crystallized sulfides in the world. It's a lovely specimen with good balance and visceral appeal. You can see wonderful, sharp, well-formed, classic, brassy colored crystals of Chalcopyrite measuring up to 1.2 associated with sharp, lustrous, black tetrahedra of Sphalerite and silvery-grey Tetrahedrite with prismatic colorless Quartz plus off-white colored rhombs of Calcite. Aside from the periphery, the piece is essentially damage free as far I can see with the naked eye. For a "black" mineral, this one certainly stands out, and looks better in person than the photos might indicate. A cool older display specimen that fits wonderfully in the palm of your hand. From the worldwide mineral collection of Albert Lewis Kidwell (January 1, 1919 - August 16, 2008). Al was a well-known mineral collector and research geologist with Carter Oil Company and later Exxon Oil Company in Houston, Texas. The phosphate species Kidwellite was named in his honor in 1974.
