A striking and aesthetic Milky Quartz crystal cluster from an uncommon Connecticut locality. Translucent, frosted and lustrous crystals with the prism faces having a drusy Quartz overgrowth. Essentially pristine, except for a trivial bit of periphery wear at the base. Quartz from Diamond Ledge is nicknamed “corncob” Quartz by collectors because of the overgrowths of smaller crystals creeping up the sides of large crystals, resembling kernels of corn.

Float Copper (Polished on one side)
Glacial Drift, Houghton County, Keweenaw Peninsula, Michigan, USA
23 x 10 x 2 cm
Ex-Hugh Hammerslag Collection
Float native Copper specimens are natural. Glaciers more than 10,000 years ago scraped the rocks of the Keweenaw Peninsula and they picked up native Copper from deposits at the surface. When the glaciers melted, pieces of naturally smooth native Copper were deposited along with sands and gravels. The gree colors are natural alterations that formed due to exposure to air and water. Areas of the specimen have been hand polished to expose some of the Copper. Float is a local term indicating that the native Copper once "floated" in a glacier.
