A spray of terminated Quartz crystals on matrix from a new find in Peru's Pisco Department. Has the appearance of a cluster of clusters and is rather unusual for Peruvian Quartz..
A fine piece from an old cache of classic Red River Floodway Gypsum crystal specimens from a find made 20 years ago in Canada. This specimen is a large, gemmy, well formed double terminated crystal  of Selenite grown outward from a central aggregate of Gypsum crystals. It is very gemmy with a beautiful golden yellow-orange color and feather-like flames of darker color within the crystal. Not your average Gypsum specimen. 
A super specimen of lustrous, golden Rutile needles on Hematite.
Wonderful cluster of very rare green Apophyllite crystals. Nice luster and rich green color due to Celadonite inclusions and, with some brownish tints due to Hematite.
Nice crystal of Copper from the famed Morenci mine.

The Morenci Copper Mine is one of the largest open-pit copper mines in the world. Located in the state of Arizona, 9.9 miles (16 km) south of Silver City, Arizona, the mine first opened for operation in 1872 and has since closed and reopened, where it is presently being worked in different stages. The Morenci is the largest producer of copper in North America
